Ingenio La Pastora, 29 de diciembre de 1929
Sr.
José Carlos Mariátegui.
Lima.
Mi admirado Mariátegui:
Debo romper la placidez de estas montañas —a las que me ha echado el agobio habanero para agradecerle mucho su cariñoso apoyo en la colaboración de Waldo Frank a la I. H. de C. Gracias a usted y al cordialísimo Samuel Glusberg pudimos palpar de cerca al gran espíritu. Gracias a usted, ponernos en contacto sincero, franco, rudo, con tan grande y honrado escritor.
Las conferencias de W. F. —que usted sin duda conoce— fueron aquí —¡gran éxito en nuestro ambiente amodorrado!— cosa discutida, polémica, apasionadora. Claro que muy pocos —y ninguno limpiamente— negaron trascendencia y alta calidad al mensaje del autor de El Redescubrimiento. Lo que más sorprendió — en un público heteróclito, todavía agradecido al combate de Santiago de Cuba-— fue la inusitada posición de un yanqui frente a su gente. La nueva postura de un extraño que no devuelve la hospitalidad en zalemas deshonestas.
La identificación del escritor yanqui con nuestro grupo —1929, ya 1930— fue absoluta, no obstante visiones y criterios distintos, Mucho se habló del grupo abnegado y valiosísimo de Lima. Mucho de usted, que tiene en W. F. un admirador de veras fraternal. Qué grato —y qué doloroso— que un hermano, pero del Norte, nos una y nos sintonice. ¡Si lo estuviésemos en verdad!
Me he traído a esta manigua sus Siete Ensayos. Quiero releerlos para terminar un ensayo sobre su libro y darlo al Número peruano de 1930. Que verá la luz si Luis Alberto Sánchez y Basadre no se duermen en las promesas.
Hace muchos meses que Amauta no nos visita. ¿Ha tenido dificultades? Sólo sabemos que Labor fue suprimida por orden paternal de Don Augusto B. Yo le ruego con mucho encarecimiento el envío de su admirable publicación. Y dígame si hay modo de colocar algunos números más de nuestra 1930.
Lo abraza, con vieja admiración, su compañero

Yorktown Heights, New York, 30 de enero de 1928
Señor Don José Carlos Mariátegui,
Lima, Perú.
My dear Brother,
I learn vía Buenos Aires of your illness, of your political difficulties and of those of Amauta: and I hasten, at this late date, to send you my profound good wishes. There is a vast silence between New York and Lima, and yet at times I seem to see you and to hear you across that abyss, crearly and warmly. I wish that you could know what help in my own struggles your own career has given me: I want you to realize that in a very true sense we are close despite the silence between us.
Glusberg writes me that he is cooperating through you and Señor Garro for the translation of Our América & Holiday: I am eager to hear details about this work. If it is being carried on under your personal supervision I have confidence in the result; and although I can realize that you have little time I hope that you are managing to keep an eye on the progress of the undertaking. As you may have read, there seems to be a strong desire in Buenos Aires to have me come down there to deliver some lectures— : and since this will be a means of representing to South America the North America which has no voice in Pan-American conference and the like, I am strongly tempted to go despite the sacrifice of time which such a journey would entail. It is possible that I may decide to make the trip, this coming Autumn. In that case, I should like to know if I might not cross over to Peru. I should hate to be so near (comparatively) to your America, without getting to know it, and getting to know you, also. If I do go to B.A. in the autumn, will you let me know (as soon as you possibly can) how much of a journey in days and in expense it would mean to cross the Andes, and if there would be some means, in Peru, of earning enough money at least to defray the cost of such a voyage? If you can possibly let me have word, before the end of March I shall be grateful.
I have recently received books of poetry from fellow Peruvians of yours: I have had no time yet to read them, and hence have not written to the poets. Will you tell them (if they are your friends) that my silence means merely that I am frightfully rushed, and that I shall get to them, before very long?
I am sending you the New Republic, in which my new book (the continuation of Our America) called The Rediscovery of America is appearing. Do you receive it?
I am eager to hear from you, my friend: to hear above all that you are again in good health, and working; and, if possible, to learn what the exact difficulties are under which Amauta and you have been laboring. I suspect that these difficulties are political, and you must know from my own work that I am close to you —in your Camp, in that matter (although I have no exact political affiliations).
I send you my brotherly greetings. The thought that there is even a bare chance of seeing you in Peru excites me.
Waldo Frank
