Broccoli as an altemative crop satisfies both requirements. Currently, broccoli is the fastestgrowing vegetable in tenns oE popularity in the United Stales (1). The increased cons umption of processed brOCCX>li is refiected l ocaUy by the increasing demand in South Texas by the írozen food industry. However, many problems h ave limite<l the establishment oí broccoli as a major crop in the Winter Carden. One such problem has been variety selection.

"MAS HONDO El SURCO, MAS ALTO El DESTINO" DERECHOS RESERVADOS. PARA CONSULTAS YSUGERENCIAS, MARQUE SIN CAIGOS '1-I00-83-333 El paso acelerado para mejorar la alfalfa J En los primeros 50 años de este siglo, los cientffi. cosque trabajan par.i \;niversidades y dependen• cias del gobierno, es dl'.!cir, los científicos al servido público, desarrollaron un buen número de va• riedades de alfalfa. En el Canadá, donde los mercados de semilk, snn relativamente peque· ños, los científicos al srrvicio público son los que predominan en los trabajos de mejoramiento de la alfalfa. No obstante, durante la década de 1960, las compañías privadas de semillas comenzaron a participar activamente en la reproducción genética de la alfalfa. Esta participación de las empresas privadas en la producción de nuevas variedades de alfalfa ha continuado desarrollándose y en la actualidad el 80 por ciento-de las variedades pro• viene de genetistas privados. Mientras tanto, para utilizar el material progeni• tor y crear nuevas variedades comerciales, los científicos al servicio público de E.U.A. han con• centrado cada vez más sus recursos en las inves· tigaciones básicas de la alfalfa, también se han preocupado en determinar estrategias genéticas y en desarrollar germoplasma mejorado para otros investigadores. Uno de los resultados de esta forma de trabajo fue el aumento notable del número de variedades introducidas en años recientes. Desde el comienzo del siglo hasta 1940, se desarrollaron únicamente 12 nuevas variedades de alfalfa en E.U.A. Luego, en las siguientes dos décadas, te introdujeron dos docenas rMS de variedades. Pero el paso acelera· do realmente comenzó en 1960, cuando aparecieron en el mercado 43 variedades. Esto sólo era el comienzo. En ta década de 1970 se introdujeron más de 100 variedades y aún fue mayor el número en ta década de 1980. Durante los últimos cuatro años, el número de nuevas variedades introdud· das fue de un promedio de 30 por año. Esto proporcionó a los productores de 'llfalfa una selección asombrosa donde escoger. Si existe algún inconveniente en el r4pido desarrollo de tantas variedades, es que este número cada vez mayor de selecciones disponibles, poei· blemente haga que sea más difidl escoger la meter variedad para las necesidades de un agricultor en particular. Pero las posibilidades de obtener ren• dimientos más altos, una mayor resistencia de las plantas y una mejor calidad de forraje, hacen que el tiempo y el esfuerzo adicional, empleados en el proceso de selección, estén ampliamente julttii· cados./George Solltnberger ELSI.JIC0 1 �TURRIALBA TURRIALBA REVISTA INTERAMERICANA DE CIENCIAS AGRICOLAS VOLUMEN 34 • TRIMESTRE ENERO-MARZO 1984 • NUMERO 1 REVISTA INTERAMERICANA DE CIENCIAS AGRICOLAS VOLUMEN 34 • • TRIMESTRE ABRIL- JUNIO 1984 Editor: ALFREDO ALY ARADO H.

Tex¡,, PR-4811 October 1990 Field Release and Recovery of Parasites of Eoreuma loftini (Lepidoptera: Pyralidae) in Su.garcane, 1989 R. S. Pfannenstiel 1, J. W. Smith , Jr. 2 and R. TJ: Meagher, Jr. 3 Summary Colonization of parasit.es as part of a classical biological control program agPinst Eoreuma lo~ini (Dyar) is documented for 1989. Five species of exotic parasit.e were released, includmgAgatJus st ,gmateris Cresson, Goniozus nataLensis Gordh, the Jal isco fly (Tachmidae, new genus near Lydella), Macrocentrus proiz(icus Wharton, and Xanthopimpla stemmator (Thurnberg). Parasitization of field collected E. loftmi from colonization sites was 10.6 percent, primarily by the noncolonized species Chelonus sonorensis Cameron and Digonogastra solitaria Wharton and Quicke, and introduced species Allorhogas pyralophagus Marsh. Recoveries of the Jalisco fly after initial releases were encouragmg, considering the small number released. Introduction The Mexican rice borer, Eoreuma loftzni (Dyar), has been the major pest of sugarcane m the Lower Rio Grande Valley (LRGV), Texas, sin ce its discovery in 1980 (Johnson, 1985). Managernent of this pest using primarily cultural and chemical control tactics has been difficult and has met wilh limited and variable success. A classical biological control effort was m1tiat.ed in 1982, and numerous exotic species were imported. cultured, and colonized. Durine the penod of 1982-1987, 11 species. were rel~aaed /Browning et al., 1985; H. W. Browmng, unpubhahed data), and 6 species recovered. This report documente relea~e and re~ove'>: of both exotic and native parasites Jn 1989, mcluding several previously released exotic parasites ~nd ~~ species initially released in 1989. Th~ paras1tes 1mtially released in 1989 were the Jahsco fly, a new solitary spec1es of Tachinidae (also new genus ~ear Lydella ) recently imported from the s~te of Jalitco, Mexico (Rodríguez del-Bosque and Sm1th, 1989), and Xanthopimpla stemmator (Thumberg), a solitary pupal parasite from southeast Asia. Materials and Methods Parasites utilized in the biological control program against E. loftini were imported, initially cultured and host screened through the Department of Ento~ology quarantine facility at ~exas A~M University, College Station. After screemng, colomes of parasit.e species designated for field release were shipped to the Texas Agricultura) Experiment ~tation in Weslaco. Rearingrnethods were then rnod1fi~~ for greater numerical mcrease on the hOAts_ E.1f,ftLni and Diatraea saccharalis (F.) and for colomzat1on. 13 •2 Rescarch ae,ociat.e and ae1111lant profcaaor resped.ively, Tcxu Agncullural Experimcnl Stalion, Weslaco, Texll8 78696.

Hay allí anexo á las escuelas primarias, lo que en sueoo se denomina Slojdlnraresemi11an'um, literalmente Seminarú, p.ir.a 1o prof~stfres de sludj trabajo n1anual). Al princi• pío (de 1874 á 18So) el objeto de este Sem111ari"u era instmir y forM mar hombres capaces de enseftar en escuelas de trabajo manual, independientes 6 anexas á las escuelas primarias. Pero en 188o se dej6 de formar profesores especiales, y tomo consecuencia de una afinna. ci6n más expltcita del sentido pecla· g6gic<1, la ensefianza normal se dirige desde entonces á proporcionar á los mismos maestros de instrttcción primaria, los conocimientos que se _iuzguen necesarios en el y bajo 1a direcci6D iurnedim slodj.

Y los cursos normales de Otto Salomón y Jobaason, que e.o 1878 tuvieron como asistentes q maestros, en 1884 llegó la cifra de estos á n 3, de los cuales ro7 eran suecos, 2 noruegos, 4 finlandeses (3 selioras), 1 danés, 2 alemanes, 5 austriacos, 2 rusos. 2 sei1oras inglesas y un holandés. Excusado paree-e indicar, que á ,·arios de estos cursos asistió Sluys, y de ellos fu€ de donde sacó los m&s sólidos fundamentos de las conclu- siones recomendadas, acerca del asunto, en su Memoria al l\Iinísterio belga. Vamos á copiar aquí las conclusiones !l. que aludimos, porque además del valor general que tienen collltl opinión de un grau pedagogo acerca de problema de tan universal importancia, plldieran considerarse como conclusiones dadas por un comisionado para el objeto al Gobierno español. Si entre noso- tros se pensara se.riamente en reformar radicalmente la escue.1a pri. maria, se \'ería el carácter e.wiuen• temeute practico de Jo que Slnys propuso eu Bélgica. Dicen Sluys y su compañero de comisión Van Kalkea: t. El trabajo manual debe formar parte del programa de las escuelas primarias, para asegurar la educación integral y armónica de todas las facultades del nino, por el desenvolvimjento progre.sfro y me. t6clico de la habilidad manual ó de la aptitud técnica, que actualmente no son objeto dee:jerdcios es pedales. ~~= y no el aprendizaje de profesioues determinadas. • 3, Pn.ra dar ú 1a cusefian1,a del trabajo manual el carácter pedagógico que debe tener, es preciso que los maestros se encarguen de ella ( r ). 4.

Es indispensable que se evite en lo sucesivo tal irregularidad, por la pcrdida de tiempo qne ocasiona eo las clases, y por~ue se perjudica notablemente la disciplina de la escuela con el tiempo, por breve que sea, en que los nifios quedan abandonados. Con tal objeto se hace saber por la preseote, que por ningún motivo debeo los maestros distraer ni la menor parte del tiempo destinado á las clases, ocupltndose en asuntos e.xtnúios á la ensefianza 1 ni en el arreglo de negocios particulares con otras personas¡ pues l1asta para re• cibir alguna queja, recomendación ú otro recado de los padres 6 tutores de los nifios, debe esperarse á que terminen las clases, 6 la hora en c¡_ue tiene lugar el recreo.

El espíritu de la familia uo es ~ espíritu de la "'CSCUcla: l()S deberes 6 las afecciones de uu hijo 6 de 1ltl hermano no son los deberes y 1afecciones de un escolar. Ctian4o se dice que una escuela ea un ~ milia, que el maestro es el padR, que los discípulos son hermanos entre s{ ~ hijos del maestro, se hace uso de una bella y conmovedora figura de estilo, de una compara• ci6n agradable á la vez al es¡mitu y placentera para el corazón· pero es indispensable ~ s e muy bien de tomar al pié de la letra semejantes expresiones. Debe ser 1& escuela en lo posible la imagen. de la familia, pero la escuela no es la familia. Es indispensable por COD.. secuencia no introducir en la um. las costumbres de la otra. Un padre, al salir, dice i su hijo: • Pablo, te dejo solo con tu hermano pequefto, vela sobre él, y si hace alguna de las cosas que le tengopro.hibidas me Jo dirás á mi Vllelta.J El padre, hablando así i Pablo y encarrindole semejante comisi6n, le realza á sus propios ojos; fort:ifi. ca en él el espíritu de familia; le asocia al cumplimiento del sagrado deber de la educaci6n. Conoce Pablo instintivamente que su padre tiene el derecho de hacerse secundar por el más razonable de sus hijos en el gobierno de 1a familia: se reconoce honrado con la confianza que se le manifiesta, y la ternura fraternal no le consiente que abuse de s11 encargo. Pero vosotros maestros, decis 6. Pablo: ,Hay alrededor de vd. algunos niño perezosos: vigílelos, y_ si no estudian, adviértamelo vd.• CoQ esto dais á Pablo una fatal lecci6zc exigis de él que se mezcle en lo que no le interesa, y le ensefw$, con vuestro ejemplo, á descaJpr en ouo Conoceis las reglas Jenerales de disciplina y su aplicación á las escttelas de niftos. Me creo, sin embargo, en el deber de llamar vuestra atención sobre algunos puntos que no se observan con bastante rigor en todas partes. Es preciso, en tan to qne sea posible, que la di$ciplina se mantenga en virtud de una exacta vigilancia por parte del maestro y por los buenos hábitos que los niiios hayan contraído, procurando que estos mismos coo~n é mantenerla, ya directa, ya 10directaniente: directamente, cuando estén encargados • por el maestro de tomar parte en la vigilancia¡ indirectamente, haciéndoles indicaciones en particular sobre la conducta de sus com¡Xlfteros. No trato de hablar en las circunstancias excepcionales qne á un maestro prudente y celoso pueden obligar á salirse de las reglas ordinarias, ni tampoco de. la marcha regularmente seguida en una clase mutua bien organizada. Pero sí os digo: (salvo estos casos que acabo de indicar.) no delegueis jamás en un alumno parte alguna de 1a autoridad que ejerceis, ni escucheis nunca acusaciones ni denuncias de boca de -vuestros discípulos. Ocupémonos de lo primero que os he dicho, esto es, de no delegar jamás en un discípulo parte alguna de vuestra autoridad. No razoneis por inducci6n de lo que pasa en las familias, donde se fllelrj'I COll fmll~'ia al ¡rimo¡é- el cumplimiento ae u clcbcr ae beid expuesto? ........ . Quiero creer que no se mostrará nunca exigente ni :injusto por ani• mosidad, por malignidad ni por despecho; pero, en fin, ¿no puede pasar esto? Y así, por vuestras imprudencias, habrán hecho los niños en la escuela el aprendizage del vicio. Dejad pues á Pablo que se ocupe tranquilamente en su propia instrucción y en su conducta propia, sin encargarle que vigile la de otro. Debo añadir sobre este punto, que no puedo aprobar la costumbre que se empieza á introducir en algunas escuelas, de llamar á los nitlos 6. decidir, por sus votos, sobre los premios que se han de dará sus camaradas, y alguna vez sobre sus faltas y sobre el castigo que ha de imponétseles. debe reflejarse sobre ellos; la dulzura y el afecto son el encanto de su edad. Concibo perfectamente que un niflo trate de disculpar á su compaflero y que pida gracia para él; pero que le juzgue y que pronuncie su castigo, eso no lo concibo yo. Hay en esto un trastorno de las relaciones establecidas por la natura• leza, que causa horror. En cuanto á los premios, estableced esta costumbre de que 1os dis. tribuyan los niftos en escrutinio secreto, y vereis lo que resuJta. Ya se ha dicho, hablando del discípulo coronado1 como para manifestar el mérito de la recompensa: ,Son sus mismos compafleros quienes le han juzgado el más digno.• ¡He aqu{ un grande honor para él maestro! ¿Es más glorioso el ser recompen• ,,. �� Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.

Y cuando digo Emilia bordó ¿debe entenderse que lo está haciendo, 6 que lo hizo ya, 6 que lo hará á la tarde 6 mafíana? . . . Hágase lo mismo para fijar la idea del \'enidero, y con esto ya se podrá explicar que la palabra borda, que dice lo que se está haciendo , en el momento en que se habla, expresa tiempo presente¡ que bortM, porque significa que la acci6n se verificó antes de aquel momento, expresa tiempo pasado, y que bordará, es venidero, porque la acción que sig• nifica no se ha ejecutado, n1 se está ejecutando, sino que esto sucederá después. P6nganseles algunos Vt:rbos en estas formas para que las distingan, y dándoles otros, hágase que ellos las varíen con relación á cada uno de los tiempos que se les acaban de enseflar. S~RAFIN PEf-lA.

Este pensamiento no es, pues, uua temeridad; es una idea madu:rada por el tiempo y que el gobierno habría tenido el inmenso mérito de realizar, probando más y más á su honor, este pensamiento que hace mucho tiempo se ha perdido de dsta. «Pensar bien y dedr binz, 110 son nada, sz'n haar bien.» ¿Cuál es pues el método de las salas de asilo, y en qué las escuelas pueden verse reemplandas por su hermana menor? En este punto sabeis tanto y mejor que yo, el mal que sufren vuestras escuelas¡ sabeis lo largo de las clases, lo árido de los libros, lo pesado del conocimiento de la teoría: el todo es un fastidio. A esta vista. mi apreciacl6n no podría ir más allá que la del gobierno, que lo fA"Presa con valor en una reciente é importante carta á los directores de la educaci6n en los Departamentos. Por otra parte, nuestras fatigas al terminar el año escolar, las penas físicas y morales que os cuesta cada día, dicen más que todo, que la mayoría de los discípulos resiste á vuestros esfuerzos, atrayéndose el reproche, acaso injusto de considerarlos indisciplinados y perezosos.

ApUDia pan una leocrl6n de Lectura Estétk&. Para terminar nuestras instrucciones sobre la Lectura Superior, presentamos un ejemplo de una ]eoci6n de Lectura Esl.ética, con el que 108 maestros principiantes puedan comprender mejor algunos de los principios relativoe ya expuestos, y formarse una idea clara de la marcha que debe seguirse en los ejercicios de éste orden de la Lectura. Tomamos al efecto una de las más bellas composiciones que trae el Libro A"'t! $ de Mantilla. El Bosque da Chapultapec. l. ¿Que fué de aquellos hermosos vetjeles, de aqueHos bosques magniflcos que los reyes de Tenochtitlán y de Tezcaco plantaron en los dfas de sa grandeza, de BU poder y de su gloria?................ !Todo fué devastado por la barbarie de los conquistadores! 2. ¡Sólo ta, bosque grandioso, has sobrevivido :'Í tanta devastación y á tantas ruinas! Tú embelleces todavía con tu frondosidad, con tu verdor y oon tus sombras, ese sitio de tantos recuerdos, t.an silencioso y lleno de misterios. Todavía en tu recinto se levantan excelsos, robustos y lozanos, aquellos ahuehuetes, bajo cuya sombra rep·só Cort~ y la hechicera Malitzín, Moctezuma. y sus concubinas, y ms guerreros valerosos. Todavía esos árboles gigantescos cubren con eu ramaje la alberca en que se bailaron tantas hermosas indias del harén de aquel sultán; y se oye aún, junto á esa alberca, aquel m1smo murmurio que adormecía á los príncipes de Anáhnac, cuando reposaban en el regazo de sus queridas, después de una victoria. Toda vía, recorriendo tu recinto, podemos eeguir aquellas sendas por donde vagaban los guardas de la corte, car.ando pájaros y alimanas; y cuando vue1an las aves entre ]as selvosas ramas de tus árboles, parece que silban en el viento las flechas que disparaban aquellos cazadores. Porque bajo tus bóvedas de verdura, en la espesura de tus excelsos ahuehuetes, y en tus veredas tortnosas y sombrías, ¡por todas partes hay recuerdos, por todas partes aparecen esas memorias de lo pasado, que por sí solas ba.ritanan para hacerte, como eres, tan hermoso. 3. Vimid á este bosque, hombres ~ne amáis la soledad, y que buscáis inspiramones. V eréis qué bello es, cuando en la al• borada del d!a interrumpen las aves con SUB silbidos el silencio con que se adormecía aquella naturaleza salvaje y misteriosa. La cnmbre de los árboles más colosalea se ilumina con el albor de la mat'lana y ent6nces resaltan más esas sombras, entre las que se mecen su:ivamente las ramas de la selva. Por entre esas ramas flotantes y sombrías pasan algunos rayos de luz, y uno que otro pájaro atravie?.a esas ráfagas volando perezoso. 4.. Al mediodía, la luz del Sol aie sobre el bosque, como una gasa de oro que flota entre las ramas.

EJERCICIOS DE LENGUAJE. Ser. !úo. 181? Dar á conocer las personas que pueden ser el sujeto del verbo. á los nifios que cuando alguno quiere expresar que él hace algo, v. g. eslttdt'ar, dice: yo estudio: que cuando se propone decir que aquel á quien dirige la palabra es el que ejecuta la acci6n, lo expresa así: tú estudias 6 usted estudia: y que si al hablar con alguno le quiere dar á entender que es otro el qne la ejecuta, emplea expresiones como ~sta: él estudia, luzs estudia. Se dirá luego que yo corresponde á la primera persona, que es la que habla: que tú y usted á la segunda, que es aquella con quien se habla, y que H, ella, Pedro etc., á la tercera, que es de la que se habla; pero que cada una de estas personas representa un solo sujeto, y por ésto se dice que están en singtllar. Cuando el que habla quiere decir que él y otro ú otros ejecutan la misma acci6n, dice: nosolros estudiamos: para dar á entender que la ejecutan aquel á quien habla y otros se expresa así: vosotros estudt'ais 6 ustedes estudian; pero si la acci6n se atribuye á dos 6 más sujetos con P1ÚCTICA.-5e dirá dice: ellos, e!!as, 6 luis y José es/11- dian. Explíquese que estas personas se llaman también primera, segunda y tercera, y que por representar 6 nombrar mas de un sujeto están en plural. Como todo ésto no deja de presentar dificultades á los niflos, es necesario que se insista mucho, repitiendo las explicaciones con diferentes verbos, hasta que les sea fácil dar la persona que se les indique, (sin preocuparnos del tiempo que se les ocurra.) r9º Conjugar el presente, pasado y venidero de los verbos regu· lares de la primera conjugación. PRÁCTICA.-El maestro escribirá en el pizarrón las personas pronominales que entran usualmente en la conjugaci6n del verbo, )'O tú, 11, nosotros, vosotros, ellos, colocándolas unas debajo de otras. En seguida, si el verbo fuere estudiar, lo escribirá aparte con los complementos de que se acordare, de este modo: estudiar-la gramática-la arzt- métz"ca-la geografía-la botánica el dioujo-la histon'a. Hecha después una ligera recor· daci6n del ejercicio N 9 17 se exigi· ri. de los nifi.os que á cada una de las personas escritas en el pizarrón se dé la forma verbal que le corresponde en el presente, afiadiendo uno de los complementos escritos á la derecha del verbo, para lo cual se les ayudará en caso necesario. La conjugación quedará así: Yo estttdio la gramática Tú estudias la aritmética El estudia la geometría Nosotros estudiamos el dibujo Vosotros estudiáis la botánica Ellos estudian la historia. Una vez aprendido esto por medio de las repeticiones necesarias se pueden hacer los ejercicios siguientes: (A) Dar los nulos la persona que se les designe con la forma ver• ¡ui~a uo so e•~ lif'blando1 i;e bal ~ue le corres¡,onda, :f3otF.TIN DE !NSTRUCCION (B) Siempre que el verbo se preste para ello hacer que se conjugue añadiendo complementos precedidos de los posesivos mi, tu, su &., según corresponda á la persona v. g. yo amo á nU:padre,- tú amas á tu padre&. (C) Unir dos 6 más personas con sus formas verbales y comple· mentos, para acostumbrar á los niños (previas las advertencias necesarias) al conveniente uso de la elipsis, v. g. si al unir las personas dijeren: yo estvd1'o la gramática, tú estudias la aritmétz"ca, y Luis y Jo· sé estudian la geografia, se les debe decir que, reuniendo estas frases en una sola, hemos de expresarnos así: yo estudio la g,amátzca, tú la aritméhca, y Luis y José la geogra fía. Con ésto, al unir las personas se exi~irá en lo de adelante 1a forma eltptica. (D) Conjugados otros verbos (en el presente), y hechos los ejercicios (A.) y (C), se con binarán una 6 más personas de uno de ellos con u.na 6 más de otro, v.g. si uno fuere sem · brar y otro regar, al pedir á los nifios una frase en que entren con el primero la primera y tercera persona de singular, y con el segundo la tercera de plural, resultará esta expresi6n: yo y él sembramos, y ellos negan. Snstitúyanse ahora los pronombres de tercera persona por nombres personales, y tendremos otra como esta: yo y JosJ sem- bramos, y Anselmo y Teodoro riegan, Todo cuanto hemos dicho sobre el modo de ensefiar la conjugación del presente es aplicable en todas sus partes á la del pasado y el venidero. 20° Conjuga!' el presente, el pasado y el venidero de los verbos regulares de la segunda conjugación. P:RÁcTicA..-Se procede en todo como en el ejercicio número 19~ 2tu Conjugar el presente, el pa- PRIMARiA. gnlares de la tercera conjugación: PRÁCTICA.-Se advierte lo mismo que eu el número anterior. 22? Conjugar en la pasiva (sin decir éste término á los niños) el presente, el pasado y el venidero de los verbos que tengan participio pasivo regular. PR.lC'I'ICA.-.Se hará ver i los ni• fios que cuando se dice; las abejas producell la miel; Dios creó el mundo; el hielo secará las plantas; es como si se dijera: la miel es producida po1 las abejas,· el mundo/ué crea. do por Dios,· las plantas serán secadas por el hielo/ y por consiguiente el presente, el pasado y el venidero pueden ser expresados en éstas otras formas. En seguida, se conjugarán los mismos tiempos, procediéndose lo mismo que en el ejercicio N '~ 19º sin otra alteración que la de escri• bir el verbo y los complementos agentes si los hubiere, en esta foro ma: ser amado-por mipad11e-pot tu l,ermano-por s11, amigo-por el maestro-por vuestros di.sápulospor los pobres, La conjugaci6n quedará así: Yo soy amado por mi padre, Tu eres amado por tu hermano El es amado por su amigo Nosotros somos amados por el maestro Vosotros sois amados por vuestros discípulos Ellos son amados por los pobres. Los ejercicios prescritos en las letras {A) y (C) del Nº 19·· caben también en esta forma de conjuga· ci6n, pudiéndose añadir á ellos el de invertir por la activa todas las personas del tiempo conjugado, si se escriben antes en el pizarrón. Debemos advertir que si se dificultase hallar un complemento di· ferente para cada persona 1 bastarán los que ha ya, y hasta uno sólo, aunque tenga que repetirse en la ndo 1 el venidero de los verbos re- conjugación, ya que 110,.aea dable ��dolo . . . i de 8118 facultada y ele • 1 cállactoa, el aer ~ e l e . . neg.al4e, ae ~ mu 1111& fa1tá ele leaftb811, é i ~ f111e actmm,. 1 . 1M aeeeeHact. ele loa ailoa- pecto? 819uesdrfe.

No teneis sino dos medios para poner término á ese azote; pero esos dos medios son infalibles: el primero es el de hacer más vivas, más interesantes y más prácticas vuestras lecciones, y el de hacer lecCÜJnes de objetos; en una palabra, intToducid en la ensefianza el método de las salas de asilo, el método natural, fisiológico, en fin, el METODO, porque por resultado de todo, no hay más que un método. así como no hay más que una sola verdad. Todas las invenciones que no proceden del método maternal, todas las que no están calcadas sobre la naturaleza, único tipo ofrecido á nuestra sagacidad, no merecen tener el nombre de método; no son sino procedimientos de fantasía, sistemas las más veces arbitrarios. Era el método que cuatro siglos antes de Jesucristo siguieron Sócrates y Pfat6n, y en nuestro siglo Pestalozzi, Froebel, el Padre Girard y una multitud de inteligencias, que más 6 menos marchan por el mismo sendero. ¿Tenía, pues, razon al decir que la idea adoptada ha sido madurada por el tiempo? Por eso este método es el único natural, y por eso es el más fecundo, el más facil de comprender y el mis c6modo para practicarse. En efecto, la propiedad de los movimientos naturales, es ser más fáciles que los movimientos falsos. Los clan ~ al cuer¡,o y lo for.. :1101 hnwttA. tifican; los otros son desagradables y rompen los miembros. Y además, el método natural no exige de los preceptores sino la aplicaci6n sincera de la inteligen· eta á la observación de los hechos diarios. El se origina de éste principio evidente: q_ue el niflo no adquiere el conocimiento de lo que le rodea, sino por medio de los sentidos¡ que los sentidos son las puertas, las ventanas, los conductos por los que las nociones del mundo visible penetran en su cerebro, para dar á su alma las sustancias de las ideas. Desde luego se a~lica á ejercitar los sentidos, á cultivar las aptitu· des especiales de ellos, á sobrevigilar su acci6n regular, á fin de que puedan recibir de una manera eneta las impresiones exteriores, y sin errores trasmitirlas á la inteligencia interior, á la reina cautiva que debe alimentarse de ellos . • • 6 emponzoflarla. En fin, él desarrolla las diversas enseflanzas intelectual y moral, bajo la forma amable y familiar que ha recibido el nombre de lecciones de objetos. Muchas veces se han citado las /ecci011es jJQr el aspecto de los alemanes¡ pero el aspecto, la aparien• cia, es demasiado falible. La apa• rienda es la que por mucho tiempo hizo creer que el sol daba vuel• tas al rededor de la tierra. La ú,cz'/m de las cosas eusefia con exacta realidad, y de cada realidad se hace brotar un conocimiento útil, un buen sentimiento 6 una buena idea. No os imagines que esta forma de lecci6n, por ser íntima y sin pretensión, deje de tener sus reglu y sus principios. Al contrario, 101 tiene fijos, y son completamente in-dependientes de la fantasía del pr& ceptor. ¿Sin esta cualidad m ~ ría ser llamada mllodo1 Sus prinpios y sus reglas son los mismoa c¡ue los de 1ae facultada clol atfa- �1JotffIN D'8 1NSTRUCC!ON PRntA1trA. dimietttrr htll!lan<11 porque los nifl<>!t Vosges1 que acaba 4e recibtr la cru ele: no son otra cosa que liot.nbres P,e'" de honor por sus cuarenta y seis aftoa • ~os.

No se discute ya la importancia que tienen, pero sí la manera más conveniente, del punto de vista pedag6gico y econ6mico, de proveer de ellos á las escuelas. Mucho se ha escrito sobre este asunto: procedimientos diversos han sido¡ropuestos, pero se ha llegado á convenir definitivamente que las escuelas deben formar sus museos con sus propios elementos. . Las diversas colecciones de que suelen ser provistas, comunmeilte son caras é incompletas, cuando no inadeeuadas por su falta de adaptaci6n al carácter nacional que debe darse á nuestra ensefianza. Las llamadas Cajas Encú:lopé'dz~ cas, mal denominadas por cierto, contienen solamente unas cuantas materias primas y algunas pocas elaboradas; están muy lejos, por lo tanto, de constituir un museo escolar. Las colecciones conocidas con el nombre de Enseñan~a Objetiva, si bien aventajan á las Cajas Encic!opédii:as por sus ilustraciones pict6ricas, tienen, por lo demás, los mismos inconvenientes de éstas. Aunque · muy poco conocidas, existen en algunas escuelas las colecciones del Musée Scolaz're de Deyrolle, que comprenden dos series de cuadros en ciento diez cartones, con excelentes grabados y setecientas muestras. Estos cuadros á pesar de su bondad, pn:sentan para nuestras escuelas tres serios inconvenientes: 1° que sus títulos y descripciones están en francés; 2° que los ejemplares elegidos en Zoología y Botánica son en su gran mayoría exóticos, y 3° que su elevado precio hace, si no imposible, por lo menos muy difícil proveer á todas las escuelas de esa obra. Descartadas, pues, las colecciones, las escuelas podrian contar ron museos apropiados, formándolos por sí mismas, es decir, mediante el trabajo de Maestros y alumnos. En muchas de ellas se ha obte• nido este resultado, y la práctica ha venido á demostrar una vez más hasta dónde se puede llegar cuando se sabe estimular y dirigir convenientemente las fuerzas del nifio, que ~isl;das parecen insignificantes, pero que aunadas con las d~ los demás, representan una canti dad de actividades capaz de producir con éxito. (Continuará.) METODOLOGIA PRACTICA. EJERCICIOS DE LENGUAJE. TERCER Aio. DESCRIPCION DE ANIMALES, VEGET !LES y o]Jjctos COlllUilBS. PRACTICA.-Pnesto á la vista de los nifios el objeto que se trata de describir, y escrito el plan en el pi · zarrón, se hará por medio de preguntas bien ordenadas que observen todo lo que debe entrar en la descripción . En seguida se hará ésta por los nifios, primero oralmente, y después por escrito, dándoseles el tiempo necesario para que la preparen, á la vista de las indicacione escritas en el pizarrón. Las dos 6 tres primeras descripciones las hará por vía de ejemplo el mismo maestro, procurando que los niños se fijen en que se ha sujetado al orden de las ideas escritas en el pizarrón. Cuando ya los nifios tengan bastante práctica en esta clase de composiciones el maestro les retirará su ayuda, primero suprimiendo las indicaciones del plan, y después el interrogatorio; pero nunca exigirá que hagan de improviso ninguna descripción. Con respecto al plan que deba adoptarse, nos parece que no puede ser uniforme, en virtud de ser tantas las variedades de los objetos, aúu de los que pertenecen al mismo género; sin embargo, para dar á conocer descriptivamente un animal, un vegetal 6 una cosa cuyas partes no sean homogéneas, es de absoluta necesidad que se expresen su especie, sus partes, las particularidades más interesantes de éstas, y las utilidades de lo que se describe, si se trata de animales 6 vegetales, ó los usos á que se destina, &.i el objeto fuere alguna cosa como un mueble, un útil, etc. Nada de ésto puede faltar en una descripción; pero á veces será necesario afiadirle algo: si el objeto, por ejemplo, tuviere una forma regular, 6 un tamafio próximamente constante, como una naranja, 6 si sus partes fueren de una misma materia, como una mesa, habrá que referir estas circunstancias al objeto, antes de la en umeraci6n de sus parte~. Se dirá, pues, que la naranja es redonda, y que tiene por diámetro un decímetro pr6ximamente, que la mesa es de madera (6 de la materia de que fuere), y que su altúra es como de n nevé decímetros. Tratándose de animales, sería conveniente incluir en la descripción las más interesantes de &.ns costumbres. Presentamos en seguida algunas descripciones conformes al plan que hemos •indicado. · · · · EL MAIZ. (E-speci:e). Es una planta que produce granos. (Partes). Se compone de raiz, tallo, hojas, flores y fruto. (Particularidades). La raiz está formada de fibras. el tallo es derecho, cilíndrico, con nudos de trecho en trecho: las hojas son largas, angostas y con venas casi paralelas: las flores son el jilote y la espiga; el primero está formado por una envoltura de hojas que prote• .. • • • • •. • • • ,._ ' • ~ 1 gen una parte interior, de la que salen por la punta del jilote unas como hebras sedosas, y la segunda se compone de flores pequefias adheridas á varios tallos, que nacen de otrp más grueso: el fruto es el jilote desarrollado, al que se dá entonces el nombre de mazorca. (Utilidades). El grano sirve de alimento en varias formas: de él se hace también almid6n, y el tallo y las hojas son un excelente forraje para las bestias. LA MARIPOSA. (Especie). Es un animalito que tiene el cuerpo formado de anillos, (Partes). Se compone de cabeza, to, rax y abdomen. (Particularidades), En la cabeza tiene dos cuer.nos largos, terminados en botón: tiene, ade. más dos antena.~, y entre ellas hay como un pelo enroscado, formando una especie de trompa, que .es la boca. El torax es velloso, y de él arrancan cuatro alas y seis patas: éstas tienen coyunturas, y las alas están cubiertas de un poi villo que les da sus hermosos colores: el abdomen es largo y casi cónico. (Cos... tumbres). Revolotea entre las flores, y á veces se posa sobre ellas para chupar la miel que contienen. (Utilidades). Fecundan las -flor-es, tras• ladando á ellas el polvillo que al• gunas necesitan de otias. UNA NARANJA. (Especie-forma-tamafio). E-& el fruto del naranjo: su forma es casi esférica, y tiene próximamente un decímetro dediámetro.(Partes). Se com pone de corteza y gajos. (Particularidades). La corteza tiene muchos hoyuelos, es muy olorosa y de color amarillo rojizo en su parte exte- . rior: los gajos están cubiertos por una inémbráná blanca, delgada· y semitransparente, que contiene una pulpa jugosa, de sabor más 6 me• nos agridulce, y las semillas qua . so~ ~la~c~s-¡ ~m.ar~a~, (l.T!i~~é\~s). �Bou?TIN DE !NsTRUccroN PiuMARIA. :tíoLETIN DE ÍNSTRuccroN PRIMARIA.

[Oontinóa.J El Ministro de instrucci6n pública, que nos hizo el honor de asistir á mi primera conferencia, me ha dirigido un reproche que he recibido con placer, y que acaso sea el más agradable que pueda escucharse: esto es, que no dije lo bastante en mi primera conferencia. <<Para ser consecuente con vos misma, me ha dicho, pues que queréis que la ensefíanza sea concreta, debéis dar el ejemplo de ello.

Se dice que poseen esta cualidad las personas que dan á sus deberes toda la importancia que realmente tienen, de tal manera que de ésto hacen un punto de honor. · Por el contrario, nadie atribu ye esta dignidad á quien no procura instruirse, 6 es desaseado, 6 se bcr'la de los demás, 6 falta á sus compromisos, etc. Si una persona, aunque sea mala, sabe que otra desprecia sus deberes, naturalmente la juzga mal: así es que qnien carece de dignidad personal, sabe esto mejor que nadie, y por consiguiente, quiera 6 no quiera, tiene que juzgarse mal á sí mismo y sentirse humillado ante su conciencia. Y no puede haber un estado más infeliz y lastimoso que el de aquel que va poi' todas partes con la vergüenza y el remordimiento pintados en el rostro. Esta infelicidad la viene á hacer mayor el desprecio con que todo el mundo lo ve, negándole las consideraciones que se guardan al hombre honrado, y los favores y ayuda que con frecuencia necesitamos los unos de los otros. EL ORGULLO. Hay personas que, juzgándose á sí mismas superiores á otras en alguna cualidad, las tratan con des- · precio, A esas personas se 1es llama orgullosas. Así, se ven ricos que, tan s6lo por serlo, humillan á los pobres: hay quienes, juzgándose instruidos, ven con desprecio á aquellos á quienes iirbauidad, iienen por iguorantes: otros hay . MATERIALES. Intelis-encia-hombre-animales Bo LETijq DE !NSTRUCCION FRIMAR!A. • • que por ser fuertes y audaces se burlan de los débiles, y no pocas veces sucede que algunos, haciendo consistir todo su mérito en la belleza del rostro, humillan á aquellos á quienes la neg6 la naturaleza El orgullo proviene principalÍnente de dos causas. r~ De que hay personas que no se conocen á sí mismas, porque el excesivo amor propio las ciega de tal manera que no pueden ver su propios defectos. 2! De que no comprenden lo que realmenta valen las cosas, de lo ·que resulta que dan una gran importancia á aquellas que nada ó casi nada significan. A los que carecen de estos conocimientos, que suelen tener hasta las personas ignorantes, se les llama tontos: así es que á los orgullosos, aunque tengan alguna instrucción, se les aplica con toda propiedad aquel feo calificativo. Hay, pues, ignorantes que no son tontos, porque se conocen á sí mismos, y respetan á los demás: á éstos se les considera en todas partes, no obstante que se lamenta su falta de instrucci6n; pero á los orgullosos, aunque tengan alguna, se les juzga como seres ridfrulos, dignos solamente del desprecio universal. Por otra parte, ¡cuántas veces sucederá que un rico orgulloso quede reducido á la miseria! ¿Con qué semblante pasará junto á aquellos á quien humillaba? Y si se vé obligado á pedir limosna, ¿qué suce· derá? Huyamos siempre de este vicio aborrecible, y dejémoslo para los que quieran merecer los calificativos de tontos y ridículos. El hombre modesto trata á todas las personas con afabilidad y benevolencia, considerando que su - naturaleza racional no es superior á la de los demás, á qt!ienes, por consiguiente, ve como él quisiera ser visto por ellos. Tanto como es odioso y ridículo el orgullo, es amable y digna de elogios la modestia. El poseerla es señal de mucho juicio, de muy buenos sentimientos, y de un gran respeto á la dignidad humana. En suma, la modestia es la demostraci6n más segura del verdadero mérito, ¿Y á- quién no agradará la pre• sencia, la compañía, la convetsación y las maneras todas de quien trata con amabilidad á los grandes y á los pequefios, á los ricos y á los pobres, á los sabios y á los igno• rantes? Por ésto la persona modesta es apreciada y respetada por cuantos tienen la dicha de conocer la. Si llega á sobrevenirle algftn contratiempo no hay quien no esté dispuesto á favorecerla, y cuando muere, se considera este acontecimiento como una desgracia no s6lo para sus amigos sino también para la sociedad entera.

El cuidado maternal se encuentra allí bajo todas las formas, á fin de atender á las necesidades de seres pequ~ños aún impotentes, que no pueden nada por sí mismos, que esperan de nuestro amor todo lo que pedimos y deseamos que devuelvan un dfa á la sociedad. Las dos primeras ocupaciones del preceptor, para cuidar de la salud de sus discípulos, deben ser las del local en que los tienen durante el dfa y el ejercicio. corporal con el que satisfacen á las necesidades orgánicas de su desarrollo. El ejercicio es el complemento indispensable de cortas sesiones. Debido á éstos frecuentes reposos, 1a inteligencia de los niños podrá dar á las lecciones la atenci6n necesaria. Porque es preciso que conozcáis que no hay amenaza, proDlesa ni castigo que pueda obtener del niño una prolongada aplicaci6n que se extienda más allá de sus fuerzas, Si se encuentra un niño capaz de permanecer atento muchas horas, sin experimentar la necesidad de cambiar de lugar, 8ería esto tnuy desfavorable para el: esto probaría que toda su actividad vital se hallaba concentrada en su cerebro, que el· equilibrio estaría interrum · pido y en peligro la salud de este nifio. ¿Habéis observado lo que pasa en la tarde al salir los niños de las escuelas, sobre todo de las escuelas donde están más obligados á guardar quietud? ¡Qué gritos, qué saltos, qué alegría, qué libertad! ¿Habéis observado lo que tiene lugar en el mismo interior de las clases cuando los niños llegan: que no estan quietos, y desean cambiar de lugar cada uno de por sí? ¡Qué ruido, qué des6rden y con frecuencia qué alboroto, qué.batahola! Para evitar estos graves inconvenientes, será bastante imitar lo que pasa en las salas de asilo, coJll,O '&e ha imitado lo que pasa en los regimientos: se marcha todos reunidos y á compás. Los regimientos tienen su música, los asilos tienen el canto. Si se dejase á los sol lados marchar uno por uno, cada uno á su paso, pronto quedarían fatigados, porque nada fatiga tanto como el des6rdeu. Los cantos de las salas de asilo son sencillos, comprensibles, y tienen por tema algun objeto moral 6 conocido de los niños, fácil de aprender. La seucilléz y la claridad son las primeras condiciones del interés que pueden tener' allí los niños: ésta es por otra parte la condici6n universal de todo aquel que quiere ensefiarlos. Es preciso no enga· fiarse y no decir como se dice á pro· p6sito de multitud de casos: «esto estáf uera del alcance de los niños.» Es muy c6moda esta aserci6n, para dispensarse de instruirlos. No: todo lo que nos es accesible y posible, lo es para los nifios. Por ejemplo, ved, si no son accesibles perfecta me¡¡. te al más elevado sentimiento, al sentimiento religioso, si no lo comprenden· y no lo sienten muchas veces mucho má~ que nosotros. Cuando un niño no comprende, es que hay desproporci6n entre él y la forma que se emplea.

Esta es una grande imperfecci6n de que facilmente se corregirá, si se toma el trabajo de pensar en ella. El can toque os aconsejo empleeis, tiene por otro lado un valor higiénico muy precioso: fortifica y desarrolla los pulmones de los nifios, los pulmones, que son los principales 6rganos de la respiración. Sa- cas y débíles se fortifican por medio de los ejercicios gimnásticos; y bien, el canto es para los pulmones una verdadera gimnasia; no hablo te6ricamente de esta materia, no acepto las teorías, sino despues de haber experimentado los hechos: he visto nifios cuyo pecho era extremadamente delicado, niños condenados por los médicos como afectados de tubérculos, curados radicalmente por el ejercicio graduado del canto. Un canto sin esfuerzo toma un movimiento de relaci6n con la naturaleza del niño: nunca debe prolongarse ni subir demasiado, ni tampoco bajar mucho: se ejecuta en pié para facilitar los movimientos del diafragma y de todos los órganos que concurren á la emisi6n de la voz: no hay cosa más conveniente á la salud, y aun á la armonía de los movimientos del cuerpo, siendo al propio tiempo una excelente preparaci6n para la enseñanza, propiamente dicha, de la música, que lle, tarde. gara, un poco' mas En cuanto al local, ya se ha hablado en términos poéticos y encantadores de los atractivos que en una casa dedicada á la educac16n deben encontrarse reunidos. Desgraciadamente la elecci6n y la disposición de los locales no depende de los preceptores: depende de las autoridades, que siempre están proclamando su .miseria: y de los arquitectos que frecuentemente toman más cuidado y gastan más dinero en la construcci6n de malas clases, que lo que sería preciso gastar para hacerlas buenas. Harían una obra meritoria los arquitectos, en la mayor parte, informándose con más minuciosidad de las necesidades de una escuela. No obstante, cuando el preceptor 6 la preceptora hayan sabido por su espíritu de orden, por su prudente conducta, por su consagración á sus deberes, conquistarse la cuando se han mostrado dignos, concluirán siempre por obtener si no locales espléndidos, al menos esas pequeñas mejoras de adorno que hacen el encanto de la vista, disponen al maestro y á los discípulos al buen humor y satisfacen á las primeras exigencias de la hi• giene. En el número de las exigencias de la higiene, se haya en primera línea la amplia y abundante circulaci6n del aire, de la luz y del sol. No hay cosa que fortifique, vivifique y que sea más indispensable al crecimiento de las tiernas plantas, como el aire, que bañando por todas partes á los nifios con sus ondas puras y renovadas sin cesar, les da la salud, la vida.

Dar á un pensamiento el mayor número de formas que fuere posible. PRAcTICA. Sea el siguiente pen· samiento: El lzsonjero es un enemi~ go más peligroso que los demás. El maestro hará la primera transformación, la que puede ser así: Cualquier enemigo puede hacernos mal; pero de nadie debemos temer tanto como del hombre que nos lisonjea. -Si queremos evitar los males que nos pueden hacer nuestros enemigos, tengamos presente que ningu· no de ellos puede hacernoslos tan grandes como los aduladores.Cualquier enemigo nos odia; pero nadie nos odia tanto como el que nos lisonjea. MA-TERIALES, Los sabios dicen muchas cosas en pocas palabras; los necios hablan mucho, y dicen poco. Un beneficio hecho fuera de tiempo más es una 'mala acci6n que un beneficio, El mundo recompensa más á menudo las apariencias del mérito que el mérito mismo. El término de la vida es muy corto; el de la belleza lo es mucho , mas. Los. avarie¡¡.tos nunca hacen bie¡¡. sino cuando mueren; los herederos se aprovechan entonces de Jo que ellos ahorraron en vida. SERAFIN PERA. T.lIMAS D.lI M0RA1. (3er. AÑO.) Toleraneia de los defeetos agenos. No hay en el mundc una sola persona que carezca de defectos, 6 que no necesite corregirse de algo. ¡Cuántos habrá que se juzgan sin defectos, porque no beben, ni jue- gan, iii roban, pero gue ha.blau !NSTRuccION 1'RIMARiA. mucho 6 son perezosos, ó prontos para enojarse, ú orgullosos ó desaseados! Interminable sería la enumeración de todos los defectos que puede tener el hombre. Pero generalmente sucede que el excesivo amor que cada uno se tiene á sí mismo, lo ciega de tal manera que no ve sus propios defectos sino los agenos, sucediendo lo que dijo Cristo: que vemos la pajita que nuestro vecino tiene en sus ojos, y no la viga que está atravezada en los nuestros. De no fijarnos en nuestros defectos proviene el que seamos intolerantes respecto de los que tienen los demás, censurándolos y burlándonos de ellos. El que tal hace se juzga superior á sus semejantes, y por consiguiente merece el odio y el desprecio con que se castiga al orgulloso. Nada tiene de malo el observar los defectos agenos, y hasta es muy útil hacerlo, siempre que no, propongamos observarnos en seguida á nosotros mismos, para corregirnos de ellos, si acaso los tenemos. Mucho nos pueden ayudar en esta parte nuestros padres, maestros y amigos, personas todas autorizadas para advertirnos nuestros defectos, á quienes debemos oir sin molestarnos, y antes agradeciéndoles esta muestra de cariño. No olvidemos que quien tenga la fortuna de conocer sus propios defectos jamás cometerá la necedad de burlarse de los agenos. RESULTADOS DE LA PEREZA. ' Este vicio feísimo lo tiene el que / se niega á trabajar, ya sea con sus ( brazos ya con su inteligencia. Esta y las fuerzas físicas nos 1 fueron dadas por el Creador, para J que hagamos uso de ellas, aplicán1 dolas al trabajo: de manera que si nos negamos á él, contrariamos este alto fin, lo cual basta para com• prender que es malísima la pereza, al estudio su inteligencia no podrá ser sino un infeliz ignoran te: el que se niega al trabajo físico, siendo pobre, vivirá siempre en la miseria, sufriendo los resultados de ésta, y haciéndola sufrir á su fami• lia. ¡Qué angustioso debe ser para un hombre presentar las manos vacías á sus hijos cuando le piden un pedazo de pan! ¡Qué triste el no poder ser útil á nadie, ni siquiera á sí mismo! El perezoso se ve obligado á veces á recurrir á la caridad pública, con lo que se convierte en una pesada carga para la sociedad, y pierde su dignidad personal, pues ya entonces no depende de sí mismo sino de los que le arrojan un mendrugo de pan. No teniendo su pensamiento ocupado en cosas útiles, forzosamente se inclinará á lo malo, por lo que los vicios serán siempre el resulta• do de la pereza y la ociosidad. El vicio de que hablamos es muy frecuente en los niños; pero recuer• den éstos, que si no lo corrigen en la primera edad, lo tendrán también cuando sean hombres, y no serán entonces más que unos seres envilecidos, dignos más bien que de lástima, del desprecio de los demás. RESULTADOS DE LA IGNORANOIA. La ignorancia consiste en carecer de aquellos conocimientos que nos son necesarios, como el de la lectura, la escritura y las cuentas, el de nuestros derechos y deberes como hombres y como ciudadanos, el de los acontecimientos más notables de la historia de nuestra Patria, el de las causas de muchos fenómenos interesantes, que se verifican á nuestra vista, etc. La inteligencia nos fué dada para que por su medio pudiéramos alcanzar éstos y otros conocimientos: el no aplicarla, pues, á este objeto, es despreciarla completamen• te: es imitar á los brutos, los cua:lea Pero ha¡_más: el ~ue uo aplica. no ¡iieu~~ eu justruir¡¡e, �BoutTIN DE INSTRUCCION PRIMARIA, 6. BoLE'l'IN DE ÍNs'.l':ru1ccroN PRU.rArüÁ. Los tristes resultados de la ignorancia son los siguiente-: El que no sabe leer se ve privado de adquirir las interesantes enseñanzas que los libros nos ofrecen, y de gozar de los encantos de mu chas de sus lecturas. El que no puede escribir nn re• cibo, una carta, 1111 contrato, etc., se verá oh ligado, cuando se le ofrezca el caso, á valerse para ello de los demás. Ya ésto de por sí es vergonzoso para cualquiera, y si se trata de un asunto que sólo debe ser conocido por la persona que dirige, ó á quien es dirigida una carta, ¿qué ~ucederá si el que se la escribe ó lee no es una persona honrada, capaz de guardar un secreto? Y ¡cuántas veces un ignorante ha sido portador de un recado que sólo contenía una amarga burla para él mismo! El que no sabe contar está expuesto á mil errores, que pueden perjudicarle en sus compras, ven tas, y en todo aquello en que se trate del dinero y el trabajo. El que no conoce sus derechos ni stls deberes es un pobre esclavo, que camina por donde otros quieren llevarlo, y si éstos lo llevan á un precipicio en él caerá sin remedio. Por eso el ignorante está expuesto á los vicios, pnes m nchas veces juzga buenas las cosas que son rua'as, y como tales las que no lo són. Tristísimo es no conocer los hechos gloriosos de nuestros héroes, ni las causas que producen tantas bellezas como nos rodean, ni ctras muchas· cosas, que encantan el espíritu y le dan mayor dignidad y grandeza. Añádase á esto que el ignorante, si es rico, es despreciado basta por los pobres, cuando saben algo; y si es pobre, en vez de mejorar algún día su situación, consumirá su vida fD trabajos durísimos, para pro¡,or- donar á los ricos carbón y piedras de cantera, y para barrerles sus patios y cahallerizas.

Tocada otra compañera se le obliga á ir á la casa de la quintera del modo arriba indica· do; después salen todas tres á la caza, unidas mano con mano. Y así continúa el juego hasta el último polluelo. Repitiéndose, la última que quedó hará de quintera. Advertencias.-Si el sitio donde se ejecuta el juego es dem_asiado es· pacioso, conviene fijar los límites, según el número y la edad de las niñas; si, durante la caza, los polluelos salen de los límites, se som.eteran á una penitencia, ó bien se privan también del juego.

Uno de los alumnos, elegido entre los que corren mejor, es ·designado por el maestro para hacer de ciervo. Los otros son divididos en cazadores y perros. Se dibuja un gran círculo y se colocan á su derredor gran número de obstáculos de ro á 30 centÍnJ.etros de altura. · Los cazadores imitan el sonido de la corneta. En el momento dado, el ciervo sale, franquea los obstáculos, se detiene, responde y salta. Los cazadores lanzan sobre él sus perros para hacerlo volver en direc· Los perros no tienen derecho de de coger al ciervo, pero tienen que pasar por todas las partes don· 4 de este último ha pasado. Cada . perro tocado por un ciervo está muerto y queda fuera del juego. Todos se estrecharán cerca del ciervo para impedir su ~arrera, los perros evitarán dejarse tocar por él. Cuando los cazadores juzguen el momento oportuno, franquearán á su turno los obstáculos y van á cercar al ciervo. Este no tiene más refugio que el estanque figurado por el círculo dibujado en el centro. Si consigne refugiarse sin haber sido tocado por los cazadores, resulta vencedor. EL COMBATE DE ENANOS. Este juego se juega por grupos de doce; se dibujan sobre el suelo, dos circunferencias concéntricas. Seis combatientes se colocan en el interior del pequefio círculo y los otros seis al exterior del grande. Aquellos del interior eligen cada uno sus adversarios. Hecha esta elección, los dos adversarios se colocan dos á dos en la zona cir· cular y parten en sentido inverso el uno á la derecha y el otro á la izquierda, saltando en cuclillas, has· ta encontrarse frente á frente: en· tonces dándose un golpe con las espaldas se empujan para hacerse salir del círculo. El que ha salido está prisionero. El combate termina luego que un bando ha sido batido y hecho pri· sionero. Si uno de los enanos se siente fatigado y quiere evitar el encuen· tro, puede escaparse saltando fuera del circulo y cuando está descansado comienza otra vez. Redactor y Responsable, . MIGUEL F.

Una vez desollado el ammal, se sacan los intestinos y todos ~os órganos internos y en segmda se despojan los huesos de la mayor cantidad posible de la carne que los rodea, teniendo cuidado di: no cortar los ligamentos de las artic_ulaciones. Hecho esto, y con el ob¡eto de quitar los pocos m{1sculos que hay,1n quedado adheridos á los huesos, se pone el ~squeleto en mace• ración en una tllla cou agua que se renueva con frecuencia.

EJERCICIOS DE LENGUAJE. OUARTO ARO. 13. Enumerar distributivamente personas, cosas 6 acciones: PRACTICA.-Supongamos que á los nifios se les dice que enumeren lo que se puede observar en una planta: de seguro contestarán qtte se pueden observar en ella la raíz, el tallo, las hojas, las flores, y el fruto. Si se les dice que formen una cláusula en que á lo anterior afiadan algo sobre cada una de estas partes, resultará una distribuci6n poco más 6 menos en los siguientes términos: «Las plantas tienen raiz, tallo, hojas, flores, y fruto. La raiz puede ser vertical, fibrosa 6 tuberosa: el tallo en los árboles y en los arbustos es consistente, y en las yérbas es débil: las hojas generalmente son verdes: las flores, si son completas, se componen de caliz, corola, estambres y pistilos; los frutos de los árboles llamados frutales tienen pepitas, como el membrillo y la pera, ó hueso, como el ciruelo y el durazno". Si se preguntara á un nifio guiéhes son los que emplean el hierro, füria que el herrero, el herrador, el ~chillero, el mecánico; si se le di- , estos artesanos exprese para que emplean aquel metal, no será difícil hacer una enumeraci6n como la siguiente: «El hierro es empleado por el herrero, para hacer llaves, aldabas, azadones y otras cosas; por el herrador, para herrar caballos; por el cuchillero, para hacer navajas, tijeras y cuchillos: y por el mecánico para construir toda clase de , . maqumas.Jl MATERIALES. ¿De ::¡ué personas necesitamos, y para qué? ¿Por qué medios conocemos los objetos exteriores, y qué conocimientos adquirimos por cada uno de los sentidos? ¿De qué están privados el ciego, el sordo y el mudo?

Eu seguida presentamos varios ejemplos de antítesis». (a) «Los nifios son inquietos, juguetones y ligeros para juzgar de las cosas; los ancianos son reposados, serios, y nunca juzgan de ningun asunto sino después de haberlo meditado suficientemente». (b) ccLos ricos gozan de muchas comodidades, viven en casas elegan tes, y los trabajos á que se dedican no son muy fatigosos; los pobres están privados de la mayor parte de las comodidades de aquellos, sus habitaciones son humildes, y se ven obligados á ocuparse en trabajos más ó menos durosJl. (c) ccEl hombre honrado vive siem pre tranquilo, y aunque sea pobre, se le estima y se le auxilia por todo el mundo; el vicioso se siente á todas horas mortificado por los remordimientos, y aunque goce de comodidades, se le ve generalmen• te con desden, y se le abandona á su suerte, cuan do necesita de los demás". (d) ccEn la primavera nos encantan los pajarillos, saltando alegres de rama en rama, y los árboles y las yerbas con el verdor de sus hojas y la belleza de sus fiores; en el invierno sentimos una profunda tristeza, porque las avecitas se hallan mudas y escondidas en la espesura de los bosques, ó entre las grietas de las rocas, y los árboles y las yerbas han sido despojados de sus hojas y sus flores por los hie· los y los vientos».

PRACTICA.-Sobre estos !!jercicios sólo tenemos que advertir que la semejanza de los objetos que se comparen no ha ser ni muy próxima, ni muy remota, y que han de ser perfectamente conocidos los caracteres que las asemejan y los que los hacen diferentes. (a) ccLos arbustos se semejan á los árboles en que sus tallos son consistentes y duran varios aflos; pero los segundos no crecen mucho, y sus ramas arrancan de muy cerca de la raíz». (b) ccLa manzana y el membrillo son casi esféricos, carnosos y tie· nen pepitas en su interior; pero el membrillo generalmente es más grande, su corteza es de un solo color, y menos tersa y lustrosa, así como su pulpa no es tan blanda, dulce ni jugosa como la de aquella». (c) ccLas ciudades, como las aldeas, se componen de muchos ha· bitantes; hay, sin embargo, una gran diferencia entre ellas. La población de las primeras es mucho más numerosa que la de las segun· das , y en ellas hay mejores edificios, templos, calles y plazas: tambien son más numerosos los talleres, las casas de comercio, las escuelas &, lo cual da al que vive en una ciudad más facilidades para proveerse de todo lo que necesita.

Se llama c6lera la ira 6 excesivo enojo que sienten al gunas perso· nas por cualquier motivo. El que éstas sean coléricas proviene casi siempre de su desmedido amor propio, que se siente molestado por cualquier causa, y de una debilidad suma, propia de las almas pequeñas, que las hace intolerantes con respecto á las faltas de los demás, porq ne no están acos· tumbradas á dominarse á sí mismas. Horrible es el aspecto que una persona presenta cuando está dominada por la ira. Su rostro se enciende y se desfigura: sus ojos inyectados de sangre tienen miradas como las del tigre: el gesto espan ta: todos su movimientos son descompasados y violentos, como los de los locos: su voz se altera y se exalta, y todo el conjuuto es el de una bestia feroz que espanta á todo el mundo. El hombre en este infeliz estado no piensa s0bre lo que hace, ni so· bre lo que dice, ni sobre lo que de ésto tiene que resultar, aun1ue después tenga que arrepentirse de ello. De la c6lera nacen las enemistades las venganzas, los insultos las riñas, los asesinatos y un sinní1ruero de los males que afligen á la humanidad. Y no solo á los demás molesta y hace sufrir el colérico, sino que también frecuentemente tiene que resentir él mismo los resultados casi siempra terribles de sus violencias. ¡Cuántos infelices estarán con el alma desgarrada por el remordimiento, llorando sin remedio en las prisiones, y haciendo llorar también á sus padres, esposas é hijos por haber asesinado á un hombre, con motivo de una ofensa que no valía la ¡>ena de haberse fijado en ella! Tened presente, oh niños, que el hombre que por la c6lera tiene la desgracia de ~s;mejar~e á l,as fier:i,s jamás llegara a dommar a nadie, porque es t~l su de~ili,da~ qu~ no puede dommarse m a s1 mismo; mientras que el hombre reposado y tranquilo, con una palabra de perd6n, deja ver á los demás un coraz6n grande y generoso, que se atrae el cariño y la admiraci6n hasta de los que alguna vez hayan sido sus enemigos. VALOR ACTIVO Y PASIVO. El primero consiste en la fortaleza de alma para arrostrar los peligros, y el segundo en sobrellevar con paciencia y resignaci6n los males y desgracias de la vida. Hay muchos casos en que nece- · sitamos armarnos de todo nuestro valor para evitar el peligro, y para no hacer mayores nuestros sufrimientos. ¿Qué hará un cobarde si se vé 6 vé á sus padres ó hijos amenazados por una fiera ó por un malvado que quiera robarlos 6 quitarles la vida? ¿Y c6mo hubiera podido nuestra Patria realizar su independencia, y defender con las armas su honor y su libertad si sus hijos hubieran sido cobardes? No es menos necesario el valor pasivo. Si nos afligen las enfermedades, si muere una persona querida, si quedamos por cualquier causa re· ducidos á la pobreza, no cabe duda de que son todos éstos unos males que hasta al rnron fuerte le arraucarán muchas lágrimas; pero el no armarnos casos de toda.la . . en estos , ., pac1enc1a y res1gnac1on necesarias es empeorar nuestra situaci6n, afia· diendo á aquellos males el de la mortificación y congoja consiguien· tes. No es malo llorar: las lágrimas son el desahogo natural del cora· zón: son las ofrendas 111ejores que depositamos sobre los sepulcros: lo malo es la desesperaci6n, la falta de conformidad con la suerte, la cual muchas veces no es sino el resultado de nuestra imprudencia y falta de previsión. las bestias, y algunas veces tam • bién á los hombres.

Pape coloca á su lado un pié de cáñamo que tiene dos metros y medio de altura, y otro pié que no tiene si no sesenta centímetros. Un torrente de risa se levanta por todos lados. «¿Qué queréis? La naturaleza hace esto en el clima de París. «En contraposición, ved el rico follaje de este hermoso cáñamo. Y ved como corre en él este precioso insecto. No descuideis este pormenor: la naturaleza es buena y hospitalaria. Deja vivir á todo Jo que ha recibido la vida. Es muy bueno enseñar á los niños á obrar como ella. Sin duda no será de un grande interes que un animal, un insecto cualquiera exista ó no exista: pero importa al más alto grado lo que los niños empiecen comprendiendo lo que vale respetar la vida, que se preserven de la desgraciada costumbre, que es d.emasiado comun, de no poder pasar al lado de un animal inofensivo, criado por la naturaleza, sin machacarlo.

Los alumnos se colocan en dos filas, por orden de estatura; los más pequeños adelante, teniendo en la extremidad del brazo levantado, una cuerda munida de cascabeles. A la orden del postillón ellos se ponen en movimiento á diferentes pasos: al paso, trote :i¡ galope. El postillón está parado sobre las espaldas de dos de sus compañeros en la posición del coloso de Rodas, un pie sobre la espalda de cada uno de los dos; la cuerda que él tiene de sus extremos le sirve para mantener su equilibrio.

Con hs patas traseras se procede de la misma manera, con la única diferencia que se ata con una cuerda el tendón de Aquiles, haciéndola pasar por la abertura anal á fin de poderla tender cuando se coloque de pie al animal. Cabeza-El arreglo de los labios consiste en reemplazar las partes carnosas con pedacitos de algodón untado con jabón arsenical espeso, ó con cera, ó también con almáciga; en seguida se rellenan las órbitas, se simulan los carrillos con estopa picada, se un ta todo con el preservativo y se vuelve la piel hasta los cartílagoq de las orejas; se pasa en seguida el sexto alambre por el medio del cuerpo y del pezcuezo, ha· ciéndolo atravesar el cráneo entre los dos ojos. ( Contziiuará.) BoLitTIN bit !NSTRUCCION PRIMARIA, del ano, se levanta la piel más abajo de las primeras vértebras coxígeas y se desarticulan éstas. Cola-Se toma entonces el peda· zo de cola ya desarticulado; con un palo hendido longitudinalmente se coloca sobre él el trozo y se hace correr el palo á lo largo del miembro, empujando con la mano derecha y reteniendo con la izquierda; estos dos esfuerzos opuestos hacen salir la cola de su envoltura. Partes superior-Colocando de panza al animal se desprende la piel por debajo de la pelvis hasta el lomo, en cuya parte se separan los miembros del tronco, manteniendo los omóplatos en su lugar después de hacer correr la piel del pescuezo hasta las últimas vértebras cervicales, dónde se desarticula la cabeza, dejando así al tronco enteramente separado de la piel. Cabeza-Se desuella en seguida la cabeza hasta la punta del hocico, tomando las más grandes precauciones para no dañar la piel. Las orejas se separan cortando su cartílago á un tercio poco más ó menos de su largo y conservando la parte má6 larga unida á la piel. Llegando á los ojos, se' da un li· gero tirón sobre la piel, para estirar la membrana nictitante y facilitar la separación entre la cabeza y la pie1 de los contornos de los ojos sin dañar los párpados. Después de sacar los ojos, cuyo color debe anotarse, y de extraer el cerebro por medio de una sonda, se quitan los músculos de la cabeza; se dejan al descubierto los miembros ha ciendo correr la piel que los envuelve, hasta la punta de los dedos; hecho esto, se raspan los huesos de modo de quitar todos los músculos. En seguida, se saca la grasa que haya quedado adherida á la piel, se cubre ésta con una capa de jabón arsenical, se rellenan los huecos y se deja secar á la sombra,. Antes de procederse al montaje se da un baño á la piel. Este baño se prepara haciendo disolver por ebullición 500 gramos de alumbre y 225 de sal marina para cinco litros de agua. Después de colocar la piel en una cubeta, se vierte sobre ella el líqui· do preparado, de modo que la cu· bra bien. La temperatura de éste no debe exceder de 30º cent. La duración del baño depende del mayor ó menor espesor de la piel, pero en general no deberá ser mayor de 24 á 48 horas, después de cu yo término se sacará aquella y se dejará secar. Montaje-Para proceder á esta operación, en el caso que la piel esté seca y dura, se puede ablandar humedeciéndola un poco. Armaz6n de alambre-Los alambres empleados con este objeto, deben tener un grosor proporcionado al peso que hayan de soportar. Se cortan cinco pedazos, de los cuales cuatro se destinan para los miembros· y el quinto para el me· dio del cuerpo; cuando la cola sea algo larga se empleará un sexto alambre, un poco más delgado que los otros. Cola-Sobre este alambre se enrolla estopa hasta darle el espesor de la parte que se va á rellenar; después de esto se unta con jabon arsenical y se introduce en la envoltura de la cola. Miembros-Se pasa á las extremidades anteriores, en las que se introducen los alambres previamente aguzados en uno de sus extremos, de modo que corran á lo largo de los huesos, á los cuales se sujetan con envolturas de hilo grueso ó estopa hasta rellenar esa parte.

Hacer resúmenes de párrafos, cuentos y fábulas (cortos) para acostumbrar á los niños á distinguir los pensamientos principales. PRACTICA.-Sea la fábula siguiente: , La Dalia, la Rosa, el Nardo y el Clavel. • Al verse sin olor la Dalia hermosa, Se juntó cierto día con la Rosa, Con el Clavel gallardo, Y con el puro y odorante Nardo, aun no había pasado un bté• ve mstante ·De estar con ellos en consorcio I\• Y mante1 • �4, , ' t!oLE'I'IN DE INSTRUCCION PRIMARÍA. Ya la Dalia inodora Se empapaba en su esencia embriagadora, Y á Nardo, á Rosa y á Clavel olia. Fruto igual, poco más, 6 poco menos, Da al malo que se junta con los buenos De la santa virtud la compañía. Después de explicar el maestro las palabras 6 expresiones que suponga desconocidas para los alumnos, y de hacer que éstos lean dos 6 tres veces la fábula, él mismo, por vía de ejemplo, expresará el primer pensamiento principal, escribiéndolo en el pizarr6n: La Dalia, flor sin aroma, se junt6 con otras flores, que eran olorosas. Preguntará luego ¿Cuál es el segundo pensamiento? ,-Cuál el tercero? Y si se dirije convenientemente á los niños, se tendrá el siguiente resumen. (a) La Dalia, flor sin aroma, se junt6 con otras flores que eran olorosas. (b) Un poco después estaba empapada en el aroma de ellas. (c) Una cosa semejante sucede á los malos que se juntan con los buenos, 18. Distinguir en una cláusula á prop6sito las oraciones principales de las secundarias, y explicar los oficios de estas. PRACTICA.-Para este ejercicio s6lo se prestan aquellas cláusulas cuyos miembros 6 partes se extienden más 6 menos, afiadiéndose á la oraci6n principal otra ú otras que la expliquen, 6 que expresen la ocasi6n, el modo, la causa, el objeto, la condici6n, el m6vil etc, de la acci6n 6 suceso que aquella expresa. Préstanse también para este ejercicio algunas cláusulas que contengan enumeraciones distributivas. Para la práctica supongamos la 11iguiente cláusula: ban alegremente en la enramada, un verde g11sani'llo, arrastrándose por un sonbrío sendero, z'ba buscando su alz'mento cuotz'dz'ano. El maestro puede preguntar de este modo: ¿de que animalito se ha- bla en esta cláusula?-¿qué se dice que hacía? (Con ésto quedará entresacada la oración principal un verde g11samllo z'ba buscando su alimento c11otidúmo.) ¿En qué época del año hacía ésto?-¿en qué ocasi6n?¿como lo hacía.? Con esto se hará observar á los niños que en la cláusula se expresa (a) lo que hacía el gusanillo, cuando se dice: un verde gusanillo t'ba buscando su alz'mento cuotidz'ano: (b) la época en que lo hacía con estas palabras Un día de verano: la ocasi6n, al decir Cllando el sol empe- zaba a derramar sus rayos sobre los campos, y los pájaros gorgeaban aleg,emente: y por fín, el modo de ejecutar la misma acci6n, con 'la frase arrastrándose por un sombrío sendero. Se les dirá, por último, que la primera, que es la que expresa lo que hacía el gusanillo, en la oraci6n 6 proposici6n principal, y que las otras son las secundarias. MATÉRIALES. A.

SERAFIN PE~A. IE:MAS DE: MORAL.. (3••· A~o.) LAS PREOCUPACIONES. Preocupaciones son los juicios 5. de conocer1as, 6 sin el previo examen de ellas. Provienen unas veces de la ligereza 6 el temor conqne se les ve, otras de los errores aprendidos á los padres iguoran tes, otras de los cuentos de las nodrizas y del miedo que estas inspiran á los niños, para que callen ó se duerman, y otras, en fin, de que son muy erradas las ideas que se tienen del gran Hacedor, Padre de la humanidad, considerándolo como un ser que se complace en prodigar toda clase de males á ~us hijos. Hay todavía innumerables personas que creen en los sueflos, las adivinaciones, las brujas, la aparici6n de los fantasmas y los muertos, los presentimientos del cora• z6n, el aúgurio de los buhos y lechuzas, la fatalidad de la suerte y de ciertos días, y un sinnúmero de preocupaciones necias y ridículas, ¿Qué relaci6n puede tener un suefio con lo porvenir? Dormido el hombre no tiene conciencia de lo que hace, ni de lo que piensa. ¿Es• tará así en mejores condiciones pa• ra conocer lo futuro que cuando tiene su pensamiento libre y en la plenitud de su ejercicio? La adivinaci6n 6 conocimiento de las cosas secretas 6 de las que están por suceder, siempre que no dependan de causas necesarias, es uno de tantos embustes de que cier• tas personas hábiles se valen para embaucar y explotar á los tontos, De las brujas 6 hechiceras se dice que por medio de tales 6 cuales signos 6 palabras misteriosas pueden causar males á personas ausentes, ó convertirlas en piedras, animales, etc. Bien, ¿y si Dios no les ha dado este maléfico don, de d6nde les ha venido? ¿Nacieron iguales á El? ¿Y si de El lo han recibido, c6mo podrá ser entendida su infinita bondad y sabiduría?

El miedo ha hecho á veces que una persona haya tomado por fantasma su propia sombra, ó algún espantajo de los que se ponen para ahuyentar las aves nocturnas. ¿Y qué diremos de la aparición de los muertos? ¿Vienen á arreglar algún asunto que dejaron pendiente, ó no más á espantar á los vivos? Si lo primero, Dios se equivocó al enviarles la muerte, pues juzgó que ya se había terminado su misión sobre la tierra; y si lo segundo, los muertos deben de ser muy traviesos y de buen humor, pues que se divierten, y tal vez hasta se ríen, espantando á los que son miedosos, pues á los que tienen valor nunca se les han aparecido. Presentir un acontecimiento que no puede ser previsto por algunos antecedentes naturales es imposible. ¿Qué hilo misterioso es el que puede comunicar hoy al corazón de una persona uu suceso que se verificará mañana tal vez á dos cien tas 6 más leguas de distancia? Todas las demás preocupaciones son tan ridículas y pueriles como éstas. Concluiremos recomendando á 1os niños que nunca juzguen de la naturaleza de las cosas sin haberlas antes examinado con valor y serenidad. Si se trata, por ejemplo de un ruido, una voz, una figura extraña, acerquémonos, oigamos, veamos, palpemos, y si la primera impresión nos inquietó, nos reiremos después de buena gana, al saber que ese ruido y esa voz eran de un gato que correteaba por la azotea, y la figura extraña era un vestido colgado de una soga para que ,ie secara allí durante la noche.

Des· pués de dar á estas extremidades la posición que cteben tener, se procede de la misma manera respecto de las posteriores, para las cuales se hace un nuevo anillo y se asegura el alambre de la cola enrollándolo en el del medio. Relleno.-Estando asegurados todos los alambres, se colocan los miembros en la posición que deben tener; se unta el pescuezo con ja· bón arsenical y se rellena con estopa picada que se atasca con un palo; se rellena también el cuerpo, dándole las formas naturales y se cose la piel.

B1NDO HUEVO LEON en dicha tabla se practican cuatro agujeros á distancias convenientes. Por estos agujeros se hacen pasar los alambres de los miembros, y se fijan por debajo de la tabla retorciéndolos en ángulo recto; se puede también mantenerlos con clavos para que no se aflojen al dar al ani- mal la posición ordinaria. Si el animal ha sido mal rellenado, se toma un punzón de lámina triangular, se hunde en el sitio que haya quedado hueco y se empareja la estopa. Es necesario atar después las cuerdas que se han ligado á los tendones. Se mantienen ten· didas colocándolas en el extremo de un palo hendido, de la altura exacta del animal. Boca, fosas nasales, orejas.-Se arregla en seguida la boca, modelando los labios y dándoles su forma primitivá. Las fosas nasales se llenan con algodón; se alisa el pelo y se mantienen las orejas en su posición natural, empleando para ello pedazos de cartón. Ojos,-Se colocan los ojos de es· malte pegándolos con goma arábiga. AVES Al matar el ave debe tenerse cuidado de dañar lo menos posible la piel y el plumaje. Si se desuella al animal en seguida de matarlo, la operación resulta mucho más fácil.

Una-vez muerta la mariposa se le quita la tira de papel y se coloca en la caja correspondiente. A los lepidópteros nocturnos, de abdomen voluminoso, se les vacía éste, rellenándolo después con al- godón y se les moja con éter duran te la disecación. Algunos suelen cortar las alas de las mariposas, las colocan sobre un papel blanco y las someten á una ligera presión. Una vez seca la goma, levantan las alas y quedan pegadas las escamitas al papel¡ después pintan el cuerpo y las antenas. De ese modo aparecen dibu· jadas las mariposas; sin i:mbargo, está demás dectr que los resultados de ese procedimiento carecen de va· lor científico.

ARACNIDOS-Se conservan en alcohol. Tanto los insectos como los áracnidos pueden conservarse con mayores ventajas, empleando el procedimiento de la maceración en el líquido de Wlckershelmer.

OUARTOilO. 23.-CONTESTACION DE CARTAS. PRÁcTICA.-Supongamos que la siguiente es la carta que debe ser contestada: · Matamoros, Junio 2 de 1897. Sr. Luis Méndez Monterrey. Muy amado hijo: Con placer te digo que ni yo ni tus hermanitos hemos tenido ningún contratiempo en nuestra salud. Es verdad que nuestra alegría no es completa, por~ue carecemos de tu amable compaiha; pero nos alienta la esperanza de que este sacrificio nos será compensad9 con tu aprovechamiento en los estudios, pues consideramos tu educaci6n como un gran tesoro para tu porvenir. No creo necesario recomendarte que en todo te conduzcan de una manera digna y decorosa, y que no · desperdicies ninguna ocasión favo· rabie para aumentar tu instrucci6n. Tu madre que piensa. mucho en tí. El maestro por medio de preguntas que hará para que los nifios expresen en pocas palabras el contenido de cada uno de los párrafos de la carta, y ayudándoles cuanto sea necesario, podrá obtener una minuta como la siguiente: (a) Salud de mamá y mis hermanos. (b) Sacrificio por mi ausencia. (c) Esperanza de mi aprovechamiento. (d) Recomendaciones. Hecho y escrito esto, se hará por medio de preguntas y sugestiones, que los nifios formen la minuta de la contestación, correspondiendo los puntos de esta á los de la carta que se ha de contestar. (a) Placer por la salud de mamá y flij liermauos, (b) Comprendo el sacrificio que ha• cen por mí. (c) Deseo vivamente corresponderá él. (d) No olvidaré las recomendacio- · _nes que se me hacen. La contestaci6n puede ser como sigue: Mamacita: por tu muy grata del 2 del corriente supe con indecible placer que ningun contratiempo ha venido á turbar tu tranquilidad y la de mis hermanitos. Comprendo en todo su valor el glande sacrificio que vdes. están haciendo al verse privados de mi compafiía, y deseo ardientemente que mi aprovechamiento deje cum· plidas las esperanzas que alien tan á vdes. para hacer ese sacrificio. Tendré siempre presente la re· comendaci6n que me haces, relativa á mi conducta, y procuraré en esta parte evitar todo lo que pueda contrariar tus justos deseos, Tu hijo que te adora, El maestro poco á poco irá retirando á los niños su ayuda para estos ejercicios¡ pero nunca dejará de revisar y corregir las minutas correspondien tes, al menos cuando en las contestaciones hubiere faltas de orden 6 cosas inoportunas ó in· conducentes, lo cual sólo puede consistir en que no se han fijado u ordenado bien los puntos á que debe corresponder la con testaci6n, resultando naturalmente que ésta tiene que resentirse de los mismos defectos. 24. Invención de cuentecitos en que figuren las personas, animales, · cosas, acciones, lugares, etc , dados por el maestro. PRÁcTrcA.-,Sean un anciano que pide limosna.-Una niña caritativa, -Otra que no lo era. Escrito este tema en el pizarrón, el mismo maestro hará oralmente la narración para dará los alumnos . ide11 do c6mo podráu eu lo de ade, t \ t !ante combinar los elementos que se les dieren. Después se limitará á proponerles estos materiales, ha· ciéndoles algunas sugestiones para hacerles ver las diferentes relacio· nes que las ideas pueden tener entre sí. El cuen tecito referido por el maestro puede ser así: «Un an· ciano andaba de puerta en puerta jmplorando la caridad. Una vez que lleg6 á la casa de Luisa, ésta, al verlo cubierto de harapos, le di6 la espalda, después de haberlo llamado sucio y perezoso. Matilde, otra nifiita que vivía frente á la casa de Luisa, oyó lo que ésta dijo al pobre anciano, y al verlo retirarse tan triste y avergonzado, se le arrasaron de lágrimas los ojos, y llamándolo, lo salud6 con dulzura, lo convidó á comer en su casa, y le regaló un vestido limpio que para ésto le dió con mucho placer su papá. El anciano, al retirarse, le besó á Matilde la mano, y llorando de agradecimiento y satisfacción, le ditigi6 estas tiernas palabras: ¡Dios, que es el padre de los pobres, te bendiga mil veces, nifiita noble y caritativa! Cuando yo me muera, tu buena acci6n será lo primero que presentaré .en el cielo á Quien te hizo tan misericordiosa.» Nos parece utilísimo tanto para ejercitar la inventiva de los niños como para estimularlos más en es· ta clase de trabajos, el que después de hacer algunos ejercicios con temas dados por el maestro, éste los invite á formar ellos mismos los materiales ó canevaes de los cuen· tecitos para proponérselos los unos á los otros: pero procurando que todos los alumnos, aun los proponentes. desarrollen cada uno de los te· mas dados, para que la correcci6n pueda ser simultánea. • MATERIALES.

Tenía 34 afíos cuando subi6 al trono de su padre, y desde el principio de su reinado mostró un orgullo desmedido, ordenando á sus súbditos que lo consideraran como un Dios, por lo cual todos tenían que fijar en tierra los ojos en su presencia. Su amor al lujo no reconoció H, mites: poseía palacios de mucha magnificencia: se le servían diaria• mente 200 platos de los manjares que tenía por más exquisitos, y pa• �k 6. 1 1 t BoL:llTIN t,:i;: ÍNS'l'Rttccr6N 1'RrMAtttA. ra sostener el lujo de su corte impu~ á los pueblos contribuciones pesadísimas. Era valiente y muy inclinado á la guerra: mientras vivió su padre, él (Moctezuma) fué general del ejército, y como tal, hizo muchas campa.ñas con resnltadosfavorables. Después, ya emperador, dos veces atacó.con un considerable ejército á los tlaxcaltecas; per.o éstos le .obligaron á retirarse'. Entonces llevó la guerra hasta Gtratemala, ganan· dp muchas batallas, y haciendo mi· llares de prisioneros, que conduci · dos á Tenochtitlan, fueron sacrificados en la inauguración de un templo. El exceso de los impuestos y la tiranía con que trataba á los pue· blos conquistados hacían que fuera odiado generalmente, y que muchas provincias sólo esperaran una oportunidad para sublevarse contra él, como lo hicieron los mixt¡,cas y los tehuantepecanos. Cortez en su camino había ofrecido á muchos pueblos su ayuda. para libertar los de la tiranía de Moctezuma: así fué qué, cpntando con los ofrecimientos que también ellos le hicieron, á lM seis días de su llegada á México le mandó que le siguiera al cuartel de los espa, ñoles.

Tuvo Cortez que salir de México para batirá Narvaez que venía de Cuba con orden de quitarle el mando, y Pedro de Alvarado, que había quedado en su lugar, sabiendo que los nobles aztecas iban á celebrar una fiesta ,re ligiosa en uno de sus templos, envió cincuenta soldados á aquel lugar con orden de matarlos, como lo hicieron, mientras ellos tranquilos y sin armas, se entrega· En ésto lega Juan de Grijalva á han á sus danzas y cantos acostum· las costas del Golfo de México: brados.

Este interés no puede ser confundido con la diversión. El uno es la vida de la imaginación, el, otro no es otra cosa que la fan tas1a. No volveré á tratar de las lecciones de cosas, por estar demasiado explicadas; s6lo os diré una pa· labra, de una ocu paci6n nsada en las salas de asilo, y que particularmente agrada á los niños: el dibujo. Cuando un niño abre un libro, la primera cosa que hace, no es leer las páginas escritas, sino mirar si tiene estampas. ¿Por qué este impulso¿ este primer movimiento, tan general, tan cierto? Porque los caracteres pequeños de hs páginas, nada dicen al niño que no sabe leer, mientras que las estampas, sepa 6 no leer, siempre dicen alguna cosa. (Continuará.) MISCELANEA. Ejercicios Corporales. JUEGOS GIMNASTICOS. (Bol eUn de Enseñanza. Primaria de Montevideo.) que se ha indicado en el juego «La zorra renga», y en el medio se hace un círculo pequefl.o, dentro del cual se coloca el cazador c,,n un látigo en la mano; todos los demás niños quedan en libertad dentro del cuadrado. El jefe de secci6n da la señal para empezar el juego, y el nifio que tiene el látigo en la mano grita: ccQuien golpe recibe, golpe devuelve», y persigue á los compañeros con pie.rengo mientras ellos cami· nan ligero entre los límites fijados. Apenas ha podido tocará un compañero, deja caer el látigo, el cual es levantado por el que fué tocado, quien poniéndose á su vez, con pie rengo persigue á los compañeros procurándo tocarlos. Y asi continúa hasta que un niño perseguido salga fuera de los limites fijados 6 que el cazador pouga los dos pies en el suelo. Si sucede que un niño ultrapasa los límites, debe hacer una penitencia corriendo desde el perímetro del cuadrado al círculo con pie rengo y soportando los golpes del cazador, empieza él el juego con el grito indicado. Si el cazador pone los dos pies en el suelo antes de haber .pegado, hace la penitencia, empieza de nuevo 6 cede el látigo al compañero que le sigue. Advertencias.-1~ El niño que por tres veces no puede tocar á un compañero, cede el látigo á otro in· dicado por el número de orden. 2~ El niño que se deje tocar por tres veces seguidas, será excluído del juego.
