En el festin del demonio!
Y era un fandango de piernas,
Y de brazos y accesorios,
Que en las secciones del cuerpo,
Rompiendo mares de estorbos,
Juraban su independencia
De apreturas y rescoldos.
Cada vaiven da materia
Para llenar quince tomos:
Por aquí gritan las viejas,
Por allá ruedan los gordos:
El negro pega unos saltos
Cual sus abuelos los monos,
Y el que no resulta herido,
Es que está al perder un ojo.
¡Qué comer! sagrado cielo!
Mejor nos fuera rastrojo,
O pedernales refritos
Con ensalada de abrojos.
Eran pedazos de oreja
De caballo, pelos de oso,
Cola de pegar maderas,
Hule con astas de toro,
Jabon con hiel y vinagre
Y de asafétida trozos.
Item; glóbulos de acíbar,
Item, caprichos de corcho,
Y por líquido elemento
Los intestinos de un pozo,
Con tremendos guzarapos
Negros, morados y rojos.
Item, un whiskey, que el bruto
Que apechuga con un sorbo,
Queda como sin aliento,
Con lágrimas en los ojos,
Y extendiendo las dos manos
Solicitando socorro.
Y es tan horrenda pintura,
Como canto melodioso
Comparada con la noche
Que fué nuestro purgatorio.
El negrazo patiabierto
Forma á las ancianas biombo,
Y sus enormes botazas
Se nos plantan en el rostro:
Este sube, el otro baja,
Hipa el uno, tose el otro,
Y se chocan contra el techo
Piernas, sorbetes y gorros.
Al rezongar del negrito
Hacen bajo los dos gordos,
Con roncar tan desalmado,
Tan majadero y tan bronco,
Que en competencia el rebuzno
Pareciera melodioso,
Y el chirriar de la carreta,
Y la algazara del gongo.
Así pasaron las horas,
Sospechando cada prójimo
(Presa casi de la asfixia
Y tostado en aquel horno),
Ver en carbon convertidos
Piés y manos, pecho y ojos,
Hasta que salió la aurora
Poniendo cara de tonto,
Sobre un llano tan ingrato,
Tan seco y tan de mal modo,
Como se junta una suegra
Con aborrecido novio,
Como se juntan dos plagas,
Como se besan dos monstruos
Como se besan dos monstruos.
La luz alumbró en el coche
Horrores, del mundo asombro:
Por aquí gorros ajados,
Por allí pálidos rostros;
Los flacos cual para-rayos,
Casi desnudos los gordos;
Y ligas, guantes, tirantes,
Como de un guiso en el bodrio,
En lagos de mantequilla
Que el conductor codicioso
Puso á nuestros piés en botes
Y que derritió el bochorno.
Con todo, al mirar la aurora,
"¿Llegamos?".... dijimos todos,
Y el conductor nos responde
Bostezando perezoso:
"Poco tiempo, otro poquita,
Como te vas San Antonio."
——
Humanidad desdichada,
Condenada cual nosotros
A pasar este suplicio,
A bramar en este potro,
Pídele á Dios que esta tierra,
Que no pisan ni los lobos,
Vergüenza de los desiertos,
De los reptiles emporio,
O se acorte ó mar se vuelva,
O la cierna un terremoto
Y del mapa desparezca,
Donde está dejando un hoyo.
Fidel.
Fuera de toda broma, el camino, si así puede llamarse la travesía de
grandes llanuras, es infernal.
En un espacio de sesenta leguas aproximativamente, hay cuatro
pequeñísimas poblaciones y los desmantelados lugares en que se
remudan las postas.
En esos parajes se detiene la diligencia unos cuantos minutos; los
pasajeros entran en tropel á una desajuarada pieza. En el centro de
ella hay una mesita insuficiente; á poca distancia se rebullen contra
el brasero unas arpías.
En la mesa impera un jarron de agua negra con el nombre de café.
Vense sembrados en la mesa platitos pequeños con tiras de jamon
como cortezas de árbol, maíces en crudo cuasi, yema de huevo
hecha picadillo, una especie de balas de masa que llaman pan; y si
la posta tiene mucho lujo, un pedazo de carne dura medio revolcada
en grasa, ceniza y cochambre, que llaman biftek. La agua es salobre,
mordente, y poblada de gusanitos inquietos.
Las poblaciones más regulares son Castroville, Orvalde, Blaskville,
Fort Clark y Paso del Aguila.
Pero solo en esta última poblacion es en la que se descansa despues
de un golpeo de dos dias.
Aunque no faltan conatos de poblaciones nuevas y cultivo, son
grandes los tramos de desierto, y el aspecto de los habitantes es
triste, bárbaro, presentando el interior de las chozas espectáculos de
verdadera miseria.
A veces, como inesperada, á la orilla de un camino se ve una tienda
de groceries, ó como si dijéramos, mestiza: á ella se agolpa la gente
y hay su remedo de tráfico.
En más de veinte años Castroville, por ejemplo, ha tenido corto
desarrollo; los carros de Durango y Chihuahua dan alguna vida á
esos lugares, y se la da el contrabando, no en direccion de Piedras
Negras como se cree generalmente, sino en la de Laredo por un
extremo, y por el otro sobre la Laguna, para dominar Zacatecas, San
Luis y Durango, sin necesidad de atravesar el desierto que media
entre el Saltillo y San Luis.
A Piedras Negras llegamos á las once de la noche, es decir, cuarenta
y seis horas de aporreo contundente.
El Grande Hotel de Eagle Pass, que tiene por frontera Piedras Negras
del lado de México, es un corral inmenso que tiene por límite un
tendido jacalon: en el corral hay macheros, cuadras y bodegas, y á
la habitacion la divide un abierto pasadizo en piezas para los
propietarios, y comedor y pieza de dormir de los mártires viajeros.
A nuestra llegada, anunciada con gritos y silbidos, aparecieron
algunos hombres en pechos de camisa, á la usanza de
Tierracaliente, con chanclas hechas de desechos de botas y botines,
mangas de camisa remangadas, brazos velludos, cabezas
alborotadas y rostros tostados por el sol y por el whiskey.
Hablaban aquellas gentes á la vez todos los idiomas; pero á
derechas, ninguno de los conocidos.
A medida que desembarcábamos del vehículo, entre muchachos,
mastines y acarreadores entrometidos, nos señalaban para
embodegarnos una pieza que por todo mueble tenia de esos catres
de tijera y lona, sin más adminículos.
Pero es el caso que muy poco se cuidaba nadie de que hubiera
correspondencia entre el número de huéspedes y el de catres; así es
que era muy comun ver que entraba uno á adjuntarse muy orondo
al otro que reposaba en profundo sueño, y solia celebrar su
advenimiento con un puñetazo.
La poblacion de Eagle Pass se halla frente por frente de Piedras
Negras, dividiendo á ambas el rio Bravo del Norte, que corre como
en una hondonada entre ambas riberas accidentadas y llenas de
desigualdades y malezas.
A trechos se ven las casitas entre las zarzas, como un rebaño
esparcido; á veces forman calle en que abundan cantinas y lugares
de tráfico.
Pero todo signo de propiedad, elegancia y hasta el recuerdo de las
ciudades de los Estados-Unidos, parece extinguirse; es el fondo de la
coladera, el resíduo de la poblacion, la orilla del mar en que se
depositan espumas y basuras.
En el sitio de la guarnicion militar se percibe más esmerada cultura.
Desde la loma en que está colocado el gran jacalon que era nuestro
hotel, más bien se sospecha que se percibe Piedras Negras.
Distínguese el lado mexicano como detrás de un muro, la plaza es
extensa y cuadrada, con sus casas bajas de cal y canto, risueñas,
abiertas de par en par y con la fisonomía característica de nuestras
poblaciones.
Yo tenia que atravesar arena y algo de mal país para percibir, como
un enamorado, mi tierra; y luego que la encontré frente á frente, le
dije una de piropos y de ternezas, que quedé como fortalecido y
contento.
Desde San Antonio habia yo escrito á mi nombre y al de Francisco al
General Naranjo, mi amigo muy querido, que nos ajustara un
carricoche y unos prácticos del terreno: sus contestaciones fueron
de lo más satisfactorias, y el coche fué de más, porque gran parte
del camino la hicimos en su carruaje y rodeados de toda clase de
atenciones.
Luego que amaneció el 6 de Agosto del año del Señor de 1877,
escribí un papelito al Sr. Zartuche, administrador de la aduana, para
que se sirviese ordenar lo conveniente para el traslado de nuestros
equipajes, que podia cargar con desembarazo una golondrina.
La respuesta fué que esperásemos al Sr. Zartuche, que se disponia á
ir por nosotros para acompañarnos.
—Pero, hombre, me decia Francisco, ¿te has vuelto loco? mírate
revolviendo tu maleta mártir, mírate sacando de su inercia eterna al
escarmenador y al cepillo. ¿Qué te sucede?
—Acicálate tú tambien, vamos á abrazar á la niña: estamos de
galanes y de novios.
Y de facto, nos poniamos de veinticinco alfileres, y garbeábamos
como unos pollos en aquel reducido espacio que nos dejaban los
catres y los yankees medio despatarrados y desnudos.
—El criado me ha dicho, decia yo, dirigiéndome á Francisco y á
riesgo de que se diese una cortada, que Naranjo mandó traer unas
buenas sandías para que refresquemos al llegar: ahí está con él ese
heróico General Falcon, honra de nuestra patria, tan fino y
caballeroso como siempre.
—¿Y el coronel Nuncio, está? me dijo Pancho, desviando la navaja
de su cara.
—Ahí lo tienes, tan seco, tan pelon y tan aparentemente brusco;
pero es finísimo: todo lo que tiene de temerario en la guerra, tiene
de dulce y de caballeroso en el trato familiar. Y ¿sabes? el viejo
Resendis, tan querido de Juarez, ahí está tambien. Anda, yo te
anudaré la corbata.
—Déjame en paz.
—Oigo el carruaje. Aquí! aquí! yo soy, Sr. Zartuche, ese Fidel muy
campechano y muy de su tierra: venga vd. por aquí.
Es el Sr. Zartuche un anciano florido y de cara abierta y bondadosa;
sus patillas, como dos motas de algodon; sus canas, cayendo en
hilos de plata sobre su frente tostada por el sol. Zartuche es la
misma probidad y el carácter más noble que se puede imaginar.
Yo dejé mi equipo á la buena de Dios, y escalé el carruajito como
mejor pude. Francisco saludó y guardó las atenciones que es debido.
Llegamos á la orilla del rio: del otro lado habia algunos curiosos.
Descendí del carruaje y me puse de pié en el chalan: veia rielando el
sol en las aguas; la orilla de la patria como que se me acercaba
tendiéndome sus brazos: me ahogaba la emocion. Cuando salté á
tierra, volví mis ojos, y de rodillas, brillando el sol en sus canas y su
hermosa frente, ví á Francisco besando la tierra de nuestra patria.
No por imitacion, sino por un acto que no podré explicar, me
descubrí tambien y apliqué mis labios á esta patria tan bella, tan
llena de infortunios, pero que se hace amar como ninguna otra
patria de la tierra.
Miéntras Francisco saludaba y le rodeaban de atenciones nuestros
amigos, yo, al rayo del sol y recargado en un desnudo tronco medio
hundido en la arena, escribia mi saludo á la patria, cuyo nombre
sagrado quiero que cierre, como un broche de diamante, el humilde
trabajo que tuve la osadía de titular: Viaje á los Estados-Unidos:
A MI PATRIA.
Quiero pegar reverente,
Patria, mi labio á tu suelo,
Miéntras me envuelve tu cielo
Con su claridad fulgente.
——
Que en la eternidad de lloro
Que derramé en el tormento,
Fué de consuelos tesoro
Soñar con este momento.
——
Y siguiendo la ilusion,
En dolorosa porfía,
Despedazarse sentia
De angustia mi corazon.
——
Pensando constante en tí
En mi soledad oscura,
Me fingia mi locura
Que hablabas dentro de mí.
——
De mi mal en los excesos,
Pidió mi voz dolorida
A Dios, no dicha, no vida....
Tu tierra para mis huesos.
——
¿Cómo la luz te alumbró
Y tus campos renovaste?
¡Oh patria! ¿pues qué, encontraste
Quien te amara como yo?
——
Cuántos arrullos sentidos,
Cuántos ecos hechiceros,
Cuántos trinos de jilgueros
Enamorando en sus nidos,
——
Te ha guardado el corazon
En ignorados cantares:
Tu nombre confié á los mares
Con entusiasta emocion.
——
Y cuando más sin fortuna,
En las playas de Occidente,
Alumbró mi triste frente
Con tibio rayo la luna,
——
Al resoplar el vapor,
Que de las ondas triunfaba,
Sollozando le contaba
Tus encantos y mi amor.
——
¡Oh! é b l d d
¡Oh! qué acerba soledad
Sin tí surge del bullicio!
¡Oh! qué atroz es el suplicio,
Oh patria, de tu orfandad!
——
Asusta la vária suerte
Con su inconstancia temida,
Tiene más ansias la vida,
Tiene más sombras la muerte!
——
Y quejoso y lastimero
Nos dice el viento al pasar:
"¿Qué sombra te ha de abrigar?
¿Quién conoce al extranjero?"
——
¡Si supieras cuál sufrí!
Si dijera el labio mio
Cómo del alma el vacío
Es espantoso sin tí!
——
A tu vista palpitante
Olvido del hado el ceño....
Dí que mi ausencia fué un sueño,
Repítelo, patria amante!
——
Patria de Hidalgo y de Juares,
g y ,
Patria de amor, patria mia,
La patria de mis cantares,
La patria de mi María,
——
Con rendida adoracion
Beso tu sagrada arena:
Está de tí mi alma llena,
Te canta mi corazon!
Guillermo Prieto.

Updated editions will replace the previous one—the old editions
will be renamed.

copyright law means that no one owns a United States
copyright in these works, so the Foundation (and you!) can copy
and distribute it in the United States without permission and
without paying copyright royalties. Special rules, set forth in the
General Terms of Use part of this license, apply to copying and
distributing Project Gutenberg™ electronic works to protect the
PROJECT GUTENBERG™ concept and trademark. Project
Gutenberg is a registered trademark, and may not be used if
you charge for an eBook, except by following the terms of the
trademark license, including paying royalties for use of the
Project Gutenberg trademark. If you do not charge anything for
copies of this eBook, complying with the trademark license is
very easy. You may use this eBook for nearly any purpose such
as creation of derivative works, reports, performances and
research. Project Gutenberg eBooks may be modified and
printed and given away—you may do practically ANYTHING in
the United States with eBooks not protected by U.S. copyright
law. Redistribution is subject to the trademark license, especially
commercial redistribution.
START: FULL LICENSE
THE FULL PROJECT GUTENBERG LICENSE

law in the United States and you are located in the United
States, we do not claim a right to prevent you from copying,
distributing, performing, displaying or creating derivative works
based on the work as long as all references to Project
Gutenberg are removed. Of course, we hope that you will

immediate access to, the full Project Gutenberg™ License must
appear prominently whenever any copy of a Project
Gutenberg™ work (any work on which the phrase “Project
Gutenberg” appears, or with which the phrase “Project
Gutenberg” is associated) is accessed, displayed, performed,
viewed, copied or distributed:
This eBook is for the use of anyone anywhere in the United
States and most other parts of the world at no cost and
with almost no restrictions whatsoever. You may copy it,
give it away or re-use it under the terms of the Project
Gutenberg License included with this eBook or online at
www.gutenberg.org. If you are not located in the United
States, you will have to check the laws of the country

contain a notice indicating that it is posted with permission of
the copyright holder), the work can be copied and distributed to
anyone in the United States without paying any fees or charges.
If you are redistributing or providing access to a work with the
phrase “Project Gutenberg” associated with or appearing on the

posted with the permission of the copyright holder, your use and
distribution must comply with both paragraphs 1.E.1 through

License for all works posted with the permission of the copyright
holder found at the beginning of this work.

Gutenberg™ License terms from this work, or any files
containing a part of this work or any other work associated with
Project Gutenberg™.

this electronic work, or any part of this electronic work, without
prominently displaying the sentence set forth in paragraph 1.E.1
with active links or immediate access to the full terms of the
Project Gutenberg™ License.

you provide access to or distribute copies of a Project
Gutenberg™ work in a format other than “Plain Vanilla ASCII” or
other format used in the official version posted on the official
Project Gutenberg™ website (www.gutenberg.org), you must,
at no additional cost, fee or expense to the user, provide a copy,
a means of exporting a copy, or a means of obtaining a copy
upon request, of the work in its original “Plain Vanilla ASCII” or
other form. Any alternate format must include the full Project
Gutenberg™ License as specified in paragraph 1.E.1.

providing access to or distributing Project Gutenberg™
electronic works provided that:

method you already use to calculate your applicable taxes. The
fee is owed to the owner of the Project Gutenberg™ trademark,
but he has agreed to donate royalties under this paragraph to
the Project Gutenberg Literary Archive Foundation. Royalty
payments must be paid within 60 days following each date on
which you prepare (or are legally required to prepare) your

as such and sent to the Project Gutenberg Literary Archive
Foundation at the address specified in Section 4, “Information
about donations to the Project Gutenberg Literary Archive
Foundation.”
• You provide a full refund of any money paid by a user who
notifies you in writing (or by e-mail) within 30 days of receipt

Gutenberg™ License. You must require such a user to return or
destroy all copies of the works possessed in a physical medium
and discontinue all use of and all access to other copies of
Project Gutenberg™ works.

any money paid for a work or a replacement copy, if a defect in
the electronic work is discovered and reported to you within 90
days of receipt of the work.

distribution of Project Gutenberg™ works.
1.E.9. If you wish to charge a fee or distribute a Project
Gutenberg™ electronic work or group of works on different
terms than are set forth in this agreement, you must obtain
permission in writing from the Project Gutenberg Literary
Archive Foundation, the manager of the Project Gutenberg™
trademark. Contact the Foundation as set forth in Section 3
below.
1.F.
1.F.1. Project Gutenberg volunteers and employees expend
considerable effort to identify, do copyright research on,
transcribe and proofread works not protected by U.S. copyright
law in creating the Project Gutenberg™ collection. Despite these
efforts, Project Gutenberg™ electronic works, and the medium
on which they may be stored, may contain “Defects,” such as,
but not limited to, incomplete, inaccurate or corrupt data,
transcription errors, a copyright or other intellectual property
infringement, a defective or damaged disk or other medium, a
computer virus, or computer codes that damage or cannot be
read by your equipment.
1.F.2. LIMITED WARRANTY, DISCLAIMER OF DAMAGES - Except
for the “Right of Replacement or Refund” described in
paragraph 1.F.3, the Project Gutenberg Literary Archive
Foundation, the owner of the Project Gutenberg™ trademark,
and any other party distributing a Project Gutenberg™ electronic
work under this agreement, disclaim all liability to you for
damages, costs and expenses, including legal fees. YOU AGREE
THAT YOU HAVE NO REMEDIES FOR NEGLIGENCE, STRICT
LIABILITY, BREACH OF WARRANTY OR BREACH OF CONTRACT
EXCEPT THOSE PROVIDED IN PARAGRAPH 1.F.3. YOU AGREE
THAT THE FOUNDATION, THE TRADEMARK OWNER, AND ANY
DISTRIBUTOR UNDER THIS AGREEMENT WILL NOT BE LIABLE
TO YOU FOR ACTUAL, DIRECT, INDIRECT, CONSEQUENTIAL,
PUNITIVE OR INCIDENTAL DAMAGES EVEN IF YOU GIVE
NOTICE OF THE POSSIBILITY OF SUCH DAMAGE.
1.F.3. LIMITED RIGHT OF REPLACEMENT OR REFUND - If you
discover a defect in this electronic work within 90 days of
receiving it, you can receive a refund of the money (if any) you
paid for it by sending a written explanation to the person you
received the work from. If you received the work on a physical
medium, you must return the medium with your written
explanation. The person or entity that provided you with the
defective work may elect to provide a replacement copy in lieu
of a refund. If you received the work electronically, the person
or entity providing it to you may choose to give you a second
opportunity to receive the work electronically in lieu of a refund.
If the second copy is also defective, you may demand a refund
in writing without further opportunities to fix the problem.
1.F.4. Except for the limited right of replacement or refund set
forth in paragraph 1.F.3, this work is provided to you ‘AS-IS’,
WITH NO OTHER WARRANTIES OF ANY KIND, EXPRESS OR
IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTIES OF
MERCHANTABILITY OR FITNESS FOR ANY PURPOSE.
1.F.5. Some states do not allow disclaimers of certain implied
warranties or the exclusion or limitation of certain types of
damages. If any disclaimer or limitation set forth in this
agreement violates the law of the state applicable to this
agreement, the agreement shall be interpreted to make the
maximum disclaimer or limitation permitted by the applicable
state law. The invalidity or unenforceability of any provision of
this agreement shall not void the remaining provisions.
1.F.6. INDEMNITY - You agree to indemnify and hold the
Foundation, the trademark owner, any agent or employee of the
Foundation, anyone providing copies of Project Gutenberg™
electronic works in accordance with this agreement, and any
volunteers associated with the production, promotion and
distribution of Project Gutenberg™ electronic works, harmless
from all liability, costs and expenses, including legal fees, that
arise directly or indirectly from any of the following which you
do or cause to occur: (a) distribution of this or any Project
Gutenberg™ work, (b) alteration, modification, or additions or
deletions to any Project Gutenberg™ work, and (c) any Defect
you cause.
Section 2. Information about the Mission
of Project Gutenberg™
Project Gutenberg™ is synonymous with the free distribution of
electronic works in formats readable by the widest variety of
computers including obsolete, old, middle-aged and new
computers. It exists because of the efforts of hundreds of
volunteers and donations from people in all walks of life.
Volunteers and financial support to provide volunteers with the
assistance they need are critical to reaching Project
Gutenberg™’s goals and ensuring that the Project Gutenberg™
collection will remain freely available for generations to come. In
2001, the Project Gutenberg Literary Archive Foundation was
created to provide a secure and permanent future for Project
Gutenberg™ and future generations. To learn more about the
Project Gutenberg Literary Archive Foundation and how your
efforts and donations can help, see Sections 3 and 4 and the
Foundation information page at www.gutenberg.org.
Section 3. Information about the Project
Gutenberg Literary Archive Foundation
The Project Gutenberg Literary Archive Foundation is a non-
profit 501(c)(3) educational corporation organized under the
laws of the state of Mississippi and granted tax exempt status
by the Internal Revenue Service. The Foundation’s EIN or
federal tax identification number is 64-6221541. Contributions
to the Project Gutenberg Literary Archive Foundation are tax
deductible to the full extent permitted by U.S. federal laws and
your state’s laws.
The Foundation’s business office is located at 809 North 1500
West, Salt Lake City, UT 84116, (801) 596-1887. Email contact
links and up to date contact information can be found at the
Foundation’s website and official page at
www.gutenberg.org/contact
Section 4. Information about Donations to
the Project Gutenberg Literary Archive
Foundation
Project Gutenberg™ depends upon and cannot survive without
widespread public support and donations to carry out its mission
of increasing the number of public domain and licensed works
that can be freely distributed in machine-readable form
accessible by the widest array of equipment including outdated
equipment. Many small donations ($1 to $5,000) are particularly
important to maintaining tax exempt status with the IRS.
The Foundation is committed to complying with the laws
regulating charities and charitable donations in all 50 states of
the United States. Compliance requirements are not uniform
and it takes a considerable effort, much paperwork and many
fees to meet and keep up with these requirements. We do not
solicit donations in locations where we have not received written
confirmation of compliance. To SEND DONATIONS or determine
the status of compliance for any particular state visit
www.gutenberg.org/donate.
While we cannot and do not solicit contributions from states
where we have not met the solicitation requirements, we know
of no prohibition against accepting unsolicited donations from
donors in such states who approach us with offers to donate.
International donations are gratefully accepted, but we cannot
make any statements concerning tax treatment of donations
received from outside the United States. U.S. laws alone swamp
our small staff.
Please check the Project Gutenberg web pages for current
donation methods and addresses. Donations are accepted in a
number of other ways including checks, online payments and
credit card donations. To donate, please visit:
www.gutenberg.org/donate.
Section 5. General Information About
Project Gutenberg™ electronic works
Professor Michael S. Hart was the originator of the Project
Gutenberg™ concept of a library of electronic works that could
be freely shared with anyone. For forty years, he produced and
distributed Project Gutenberg™ eBooks with only a loose
network of volunteer support.
Project Gutenberg™ eBooks are often created from several
printed editions, all of which are confirmed as not protected by
copyright in the U.S. unless a copyright notice is included. Thus,
we do not necessarily keep eBooks in compliance with any
particular paper edition.
Most people start at our website which has the main PG search
facility: www.gutenberg.org.
This website includes information about Project Gutenberg™,
including how to make donations to the Project Gutenberg
Literary Archive Foundation, how to help produce our new
eBooks, and how to subscribe to our email newsletter to hear
about new eBooks.
Welcome to our website – the ideal destination for book lovers and
knowledge seekers. With a mission to inspire endlessly, we offer a
vast collection of books, ranging from classic literary works to
specialized publications, self-development books, and children's
literature. Each book is a new journey of discovery, expanding

  • 22. En el festin del demonio! Y era un fandango de piernas, Y de brazos y accesorios, Que en las secciones del cuerpo, Rompiendo mares de estorbos, Juraban su independencia De apreturas y rescoldos. Cada vaiven da materia Para llenar quince tomos: Por aquí gritan las viejas, Por allá ruedan los gordos: El negro pega unos saltos Cual sus abuelos los monos, Y el que no resulta herido, Es que está al perder un ojo. ¡Qué comer! sagrado cielo! Mejor nos fuera rastrojo, O pedernales refritos Con ensalada de abrojos. Eran pedazos de oreja De caballo, pelos de oso, Cola de pegar maderas, Hule con astas de toro, Jabon con hiel y vinagre Y de asafétida trozos. Item; glóbulos de acíbar, Item, caprichos de corcho, Y por líquido elemento Los intestinos de un pozo, Con tremendos guzarapos Negros, morados y rojos. Item, un whiskey, que el bruto Que apechuga con un sorbo, Queda como sin aliento, Con lágrimas en los ojos, Y extendiendo las dos manos
  • 23. Solicitando socorro. Y es tan horrenda pintura, Como canto melodioso Comparada con la noche Que fué nuestro purgatorio. El negrazo patiabierto Forma á las ancianas biombo, Y sus enormes botazas Se nos plantan en el rostro: Este sube, el otro baja, Hipa el uno, tose el otro, Y se chocan contra el techo Piernas, sorbetes y gorros. Al rezongar del negrito Hacen bajo los dos gordos, Con roncar tan desalmado, Tan majadero y tan bronco, Que en competencia el rebuzno Pareciera melodioso, Y el chirriar de la carreta, Y la algazara del gongo. Así pasaron las horas, Sospechando cada prójimo (Presa casi de la asfixia Y tostado en aquel horno), Ver en carbon convertidos Piés y manos, pecho y ojos, Hasta que salió la aurora Poniendo cara de tonto, Sobre un llano tan ingrato, Tan seco y tan de mal modo, Como se junta una suegra Con aborrecido novio, Como se juntan dos plagas, Como se besan dos monstruos
  • 24. Como se besan dos monstruos. La luz alumbró en el coche Horrores, del mundo asombro: Por aquí gorros ajados, Por allí pálidos rostros; Los flacos cual para-rayos, Casi desnudos los gordos; Y ligas, guantes, tirantes, Como de un guiso en el bodrio, En lagos de mantequilla Que el conductor codicioso Puso á nuestros piés en botes Y que derritió el bochorno. Con todo, al mirar la aurora, "¿Llegamos?".... dijimos todos, Y el conductor nos responde Bostezando perezoso: "Poco tiempo, otro poquita, Como te vas San Antonio." —— Humanidad desdichada, Condenada cual nosotros A pasar este suplicio, A bramar en este potro, Pídele á Dios que esta tierra, Que no pisan ni los lobos, Vergüenza de los desiertos, De los reptiles emporio, O se acorte ó mar se vuelva, O la cierna un terremoto Y del mapa desparezca, Donde está dejando un hoyo. Fidel.
  • 25. Fuera de toda broma, el camino, si así puede llamarse la travesía de grandes llanuras, es infernal. En un espacio de sesenta leguas aproximativamente, hay cuatro pequeñísimas poblaciones y los desmantelados lugares en que se remudan las postas. En esos parajes se detiene la diligencia unos cuantos minutos; los pasajeros entran en tropel á una desajuarada pieza. En el centro de ella hay una mesita insuficiente; á poca distancia se rebullen contra el brasero unas arpías. En la mesa impera un jarron de agua negra con el nombre de café. Vense sembrados en la mesa platitos pequeños con tiras de jamon como cortezas de árbol, maíces en crudo cuasi, yema de huevo hecha picadillo, una especie de balas de masa que llaman pan; y si la posta tiene mucho lujo, un pedazo de carne dura medio revolcada en grasa, ceniza y cochambre, que llaman biftek. La agua es salobre, mordente, y poblada de gusanitos inquietos. Las poblaciones más regulares son Castroville, Orvalde, Blaskville, Fort Clark y Paso del Aguila. Pero solo en esta última poblacion es en la que se descansa despues de un golpeo de dos dias. Aunque no faltan conatos de poblaciones nuevas y cultivo, son grandes los tramos de desierto, y el aspecto de los habitantes es triste, bárbaro, presentando el interior de las chozas espectáculos de verdadera miseria. A veces, como inesperada, á la orilla de un camino se ve una tienda de groceries, ó como si dijéramos, mestiza: á ella se agolpa la gente y hay su remedo de tráfico. En más de veinte años Castroville, por ejemplo, ha tenido corto desarrollo; los carros de Durango y Chihuahua dan alguna vida á esos lugares, y se la da el contrabando, no en direccion de Piedras
  • 26. Negras como se cree generalmente, sino en la de Laredo por un extremo, y por el otro sobre la Laguna, para dominar Zacatecas, San Luis y Durango, sin necesidad de atravesar el desierto que media entre el Saltillo y San Luis. A Piedras Negras llegamos á las once de la noche, es decir, cuarenta y seis horas de aporreo contundente. El Grande Hotel de Eagle Pass, que tiene por frontera Piedras Negras del lado de México, es un corral inmenso que tiene por límite un tendido jacalon: en el corral hay macheros, cuadras y bodegas, y á la habitacion la divide un abierto pasadizo en piezas para los propietarios, y comedor y pieza de dormir de los mártires viajeros. A nuestra llegada, anunciada con gritos y silbidos, aparecieron algunos hombres en pechos de camisa, á la usanza de Tierracaliente, con chanclas hechas de desechos de botas y botines, mangas de camisa remangadas, brazos velludos, cabezas alborotadas y rostros tostados por el sol y por el whiskey. Hablaban aquellas gentes á la vez todos los idiomas; pero á derechas, ninguno de los conocidos. A medida que desembarcábamos del vehículo, entre muchachos, mastines y acarreadores entrometidos, nos señalaban para embodegarnos una pieza que por todo mueble tenia de esos catres de tijera y lona, sin más adminículos. Pero es el caso que muy poco se cuidaba nadie de que hubiera correspondencia entre el número de huéspedes y el de catres; así es que era muy comun ver que entraba uno á adjuntarse muy orondo al otro que reposaba en profundo sueño, y solia celebrar su advenimiento con un puñetazo. La poblacion de Eagle Pass se halla frente por frente de Piedras Negras, dividiendo á ambas el rio Bravo del Norte, que corre como en una hondonada entre ambas riberas accidentadas y llenas de desigualdades y malezas.
  • 27. A trechos se ven las casitas entre las zarzas, como un rebaño esparcido; á veces forman calle en que abundan cantinas y lugares de tráfico. Pero todo signo de propiedad, elegancia y hasta el recuerdo de las ciudades de los Estados-Unidos, parece extinguirse; es el fondo de la coladera, el resíduo de la poblacion, la orilla del mar en que se depositan espumas y basuras. En el sitio de la guarnicion militar se percibe más esmerada cultura. Desde la loma en que está colocado el gran jacalon que era nuestro hotel, más bien se sospecha que se percibe Piedras Negras. Distínguese el lado mexicano como detrás de un muro, la plaza es extensa y cuadrada, con sus casas bajas de cal y canto, risueñas, abiertas de par en par y con la fisonomía característica de nuestras poblaciones. Yo tenia que atravesar arena y algo de mal país para percibir, como un enamorado, mi tierra; y luego que la encontré frente á frente, le dije una de piropos y de ternezas, que quedé como fortalecido y contento. Desde San Antonio habia yo escrito á mi nombre y al de Francisco al General Naranjo, mi amigo muy querido, que nos ajustara un carricoche y unos prácticos del terreno: sus contestaciones fueron de lo más satisfactorias, y el coche fué de más, porque gran parte del camino la hicimos en su carruaje y rodeados de toda clase de atenciones. Luego que amaneció el 6 de Agosto del año del Señor de 1877, escribí un papelito al Sr. Zartuche, administrador de la aduana, para que se sirviese ordenar lo conveniente para el traslado de nuestros equipajes, que podia cargar con desembarazo una golondrina. La respuesta fué que esperásemos al Sr. Zartuche, que se disponia á ir por nosotros para acompañarnos.
  • 28. —Pero, hombre, me decia Francisco, ¿te has vuelto loco? mírate revolviendo tu maleta mártir, mírate sacando de su inercia eterna al escarmenador y al cepillo. ¿Qué te sucede? —Acicálate tú tambien, vamos á abrazar á la niña: estamos de galanes y de novios. Y de facto, nos poniamos de veinticinco alfileres, y garbeábamos como unos pollos en aquel reducido espacio que nos dejaban los catres y los yankees medio despatarrados y desnudos. —El criado me ha dicho, decia yo, dirigiéndome á Francisco y á riesgo de que se diese una cortada, que Naranjo mandó traer unas buenas sandías para que refresquemos al llegar: ahí está con él ese heróico General Falcon, honra de nuestra patria, tan fino y caballeroso como siempre. —¿Y el coronel Nuncio, está? me dijo Pancho, desviando la navaja de su cara. —Ahí lo tienes, tan seco, tan pelon y tan aparentemente brusco; pero es finísimo: todo lo que tiene de temerario en la guerra, tiene de dulce y de caballeroso en el trato familiar. Y ¿sabes? el viejo Resendis, tan querido de Juarez, ahí está tambien. Anda, yo te anudaré la corbata. —Déjame en paz. —Oigo el carruaje. Aquí! aquí! yo soy, Sr. Zartuche, ese Fidel muy campechano y muy de su tierra: venga vd. por aquí. Es el Sr. Zartuche un anciano florido y de cara abierta y bondadosa; sus patillas, como dos motas de algodon; sus canas, cayendo en hilos de plata sobre su frente tostada por el sol. Zartuche es la misma probidad y el carácter más noble que se puede imaginar. Yo dejé mi equipo á la buena de Dios, y escalé el carruajito como mejor pude. Francisco saludó y guardó las atenciones que es debido.
  • 29. Llegamos á la orilla del rio: del otro lado habia algunos curiosos. Descendí del carruaje y me puse de pié en el chalan: veia rielando el sol en las aguas; la orilla de la patria como que se me acercaba tendiéndome sus brazos: me ahogaba la emocion. Cuando salté á tierra, volví mis ojos, y de rodillas, brillando el sol en sus canas y su hermosa frente, ví á Francisco besando la tierra de nuestra patria. No por imitacion, sino por un acto que no podré explicar, me descubrí tambien y apliqué mis labios á esta patria tan bella, tan llena de infortunios, pero que se hace amar como ninguna otra patria de la tierra. Miéntras Francisco saludaba y le rodeaban de atenciones nuestros amigos, yo, al rayo del sol y recargado en un desnudo tronco medio hundido en la arena, escribia mi saludo á la patria, cuyo nombre sagrado quiero que cierre, como un broche de diamante, el humilde trabajo que tuve la osadía de titular: Viaje á los Estados-Unidos: A MI PATRIA.
  • 30. Quiero pegar reverente, Patria, mi labio á tu suelo, Miéntras me envuelve tu cielo Con su claridad fulgente. —— Que en la eternidad de lloro Que derramé en el tormento, Fué de consuelos tesoro Soñar con este momento. —— Y siguiendo la ilusion, En dolorosa porfía, Despedazarse sentia De angustia mi corazon. —— Pensando constante en tí En mi soledad oscura, Me fingia mi locura Que hablabas dentro de mí. —— De mi mal en los excesos, Pidió mi voz dolorida A Dios, no dicha, no vida.... Tu tierra para mis huesos. ——
  • 31. ¿Cómo la luz te alumbró Y tus campos renovaste? ¡Oh patria! ¿pues qué, encontraste Quien te amara como yo? —— Cuántos arrullos sentidos, Cuántos ecos hechiceros, Cuántos trinos de jilgueros Enamorando en sus nidos, —— Te ha guardado el corazon En ignorados cantares: Tu nombre confié á los mares Con entusiasta emocion. —— Y cuando más sin fortuna, En las playas de Occidente, Alumbró mi triste frente Con tibio rayo la luna, —— Al resoplar el vapor, Que de las ondas triunfaba, Sollozando le contaba Tus encantos y mi amor. —— ¡Oh! é b l d d
  • 32. ¡Oh! qué acerba soledad Sin tí surge del bullicio! ¡Oh! qué atroz es el suplicio, Oh patria, de tu orfandad! —— Asusta la vária suerte Con su inconstancia temida, Tiene más ansias la vida, Tiene más sombras la muerte! —— Y quejoso y lastimero Nos dice el viento al pasar: "¿Qué sombra te ha de abrigar? ¿Quién conoce al extranjero?" —— ¡Si supieras cuál sufrí! Si dijera el labio mio Cómo del alma el vacío Es espantoso sin tí! —— A tu vista palpitante Olvido del hado el ceño.... Dí que mi ausencia fué un sueño, Repítelo, patria amante! —— Patria de Hidalgo y de Juares,
  • 33. g y , Patria de amor, patria mia, La patria de mis cantares, La patria de mi María, —— Con rendida adoracion Beso tu sagrada arena: Está de tí mi alma llena, Te canta mi corazon! Guillermo Prieto. Piedras Negras, Agosto 6 de 1877. FIN DEL TOMO TERCERO Y ULTIMO

Section 2. Information about the Mission of Project Gutenberg™
  • 52. Project Gutenberg™ is synonymous with the free distribution of electronic works in formats readable by the widest variety of computers including obsolete, old, middle-aged and new computers. It exists because of the efforts of hundreds of volunteers and donations from people in all walks of life. Volunteers and financial support to provide volunteers with the assistance they need are critical to reaching Project Gutenberg™’s goals and ensuring that the Project Gutenberg™ collection will remain freely available for generations to come. In 2001, the Project Gutenberg Literary Archive Foundation was created to provide a secure and permanent future for Project Gutenberg™ and future generations. To learn more about the Project Gutenberg Literary Archive Foundation and how your efforts and donations can help, see Sections 3 and 4 and the Foundation information page at www.gutenberg.org. Section 3. Information about the Project Gutenberg Literary Archive Foundation The Project Gutenberg Literary Archive Foundation is a non- profit 501(c)(3) educational corporation organized under the laws of the state of Mississippi and granted tax exempt status by the Internal Revenue Service. The Foundation’s EIN or federal tax identification number is 64-6221541. Contributions to the Project Gutenberg Literary Archive Foundation are tax deductible to the full extent permitted by U.S. federal laws and your state’s laws. The Foundation’s business office is located at 809 North 1500 West, Salt Lake City, UT 84116, (801) 596-1887.

  • 53. Section 4. Information about Donations to the Project Gutenberg Literary Archive Foundation Project Gutenberg™ depends upon and cannot survive without widespread public support and donations to carry out its mission of increasing the number of public domain and licensed works that can be freely distributed in machine-readable form accessible by the widest array of equipment including outdated equipment. Many small donations ($1 to $5,000) are particularly important to maintaining tax exempt status with the IRS. The Foundation is committed to complying with the laws regulating charities and charitable donations in all 50 states of the United States. Compliance requirements are not uniform and it takes a considerable effort, much paperwork and many fees to meet and keep up with these requirements. We do not solicit donations in locations where we have not received written confirmation of compliance. To SEND DONATIONS or determine the status of compliance for any particular state visit www.gutenberg.org/donate. While we cannot and do not solicit contributions from states where we have not met the solicitation requirements, we know of no prohibition against accepting unsolicited donations from donors in such states who approach us with offers to donate. International donations are gratefully accepted, but we cannot make any statements concerning tax treatment of donations received from outside the United States. U.S. laws alone swamp our small staff. Please check the Project Gutenberg web pages for current donation methods and addresses. Donations are accepted in a number of other ways including checks, online payments and
  • 54. credit card donations. To donate, please visit: www.gutenberg.org/donate. Section 5. General Information About Project Gutenberg™ electronic works Professor Michael S. Hart was the originator of the Project Gutenberg™ concept of a library of electronic works that could be freely shared with anyone. For forty years, he produced and distributed Project Gutenberg™ eBooks with only a loose network of volunteer support. Project Gutenberg™ eBooks are often created from several printed editions, all of which are confirmed as not protected by copyright in the U.S. unless a copyright notice is included. Thus, we do not necessarily keep eBooks in compliance with any particular paper edition. Most people start at our website which has the main PG search facility: www.gutenberg.org. This website includes information about Project Gutenberg™, including how to make donations to the Project Gutenberg Literary Archive Foundation, how to help produce our new eBooks, and how to subscribe to our email newsletter to hear about new eBooks.
