Sr. Don José Carlos Mariátegui
Lima, Perú.
My friend:
Señor Llanos has sent me the review containing your splendid and generous article on —I will not say my work— but on my intentions, at least. I do not know how to thank you for this tribute. I have already read work of yours in various periodicals; and my respect for you makes me the more humble before this gracious salute from South America. I cannot feel, that I have altogether failed, when this kind of thing is given me. Life here in “Yanquilandia” is very very hard for the artist, for the man who deliberately sets himself against the most stupendously successful materialistic movement in all history. But life is not hopeless. Such words as yours are the Manna which enable me to survive in what I often, when I am weary and disheartened, feel to be the Desert of our age. Thank... Deeply, deeply, my thanks...
yours
Waldo Frank
PS Would it be possible for me to have two more copies of this article?

Dear Friend,
I have nor written you, since I received your book and since you sent your so penetrating and so generous discussion of Rahab. I was happy to read your Escena Contemporanea and to learn from it how close and parallel our awareness of life and our approach to our epoch’s problems are. I feel, that I have won, in distant Peru, a true deep friend and I am grateful.
Tell me, do you read English? If so, I should like to send you books of mine which have not as yet appeared in translation. I feel that I have the right to call on you to read me fully. On the other hand if you are not familiar with English, please tell me, in order that I may henceforth to write you in French (I read Spanish, but I fear I am not at home enough in that language to write a letter in it, without horrible mistakes).
I have read with greatest interest the two issues of El Sembrador sent me by Ramirez i Castillo. How refreshing it is, to learn that there are bodies in South America with such clear, strong purposes. How I wish I could more actually join you! That is the misery of our time: it is so incredibly hard to turn vision and our right impulse into Act. A Union of Latin America— that would be the best thing not alone for all of you, but for us too. If we in the U.S. could realise the existence, south of us, of a mature, integrated world, it would help to sober us from the insane and unchallenged madness of our material success.
You must realise ––all of yo–– that I am with you in spirit. The America I am concerned with is one that can only consider your own America in the light of an equal. And as to you, personally, dear Mariategui, I am happy that you have been moved by my work to write as you have written: I am happy that you are there, at work like myself in the great adventure of making of America a new world indeed. I hope that our realisations will grow closer. I salute you, with deep gratitude and thanksgiving and joyousness.
yours
Waldo Frank

Estimado compañero:
Adjuntamos un giro de $ 10.00 (dólares) pagando el artículo que nos envió sobre los problemas del indio del Perú.
Queremos advertirle que nuestros artículos están destinados para la prensa diaria y por eso sería mejor escribir más sobre los problemas actuales y sobre asuntos que se completan en el mismo artículo.
Esperamos otro artículo pronto.
Le saluda cordialmente

New York, 2 de julio [de 1928]
Sr. Don José Carlos Mariátegui
Lima, Perú.
Dear friend,
I wrote you some time ago, telling you with what delight I have been reading Amauta. It is a remarkable magazine; and I have a very real sense of the importance of the work you are doing. It means a good deal to me, to be able to count you among my friends.
I noticed with pleasure that you have been publishing certain chapters of my Re-Discovery of America. I am glad that you considered it worth publishing. I shall have to ask you, however, to cease these publications. I am trying to sell the Spanish rights of this book to a newspape— and I cannot afford to lose the possibility of earning this money, through the appearance in Amauta in which I receive no pay. Will you kindly tell Sr. Garro (whose address I do not have) that I thank him for his interest; that I am delighted to know that he is translating Our America for Glusberg of Buenos Aires but that I hope he is not translating any more parts of the new book?
Do let me hear from you. It is a long long time since I have had a letter from you, personally. I wonder indeed if you received my last one. And I shall be wondering if this word reaches you, until you assure me.
cordially yours
Waldo Frank

Compañero:
Sin embargo de lo que le digo en mi principal de ayer, creo que conviene ir, poco a poco, filtrando nuestro pensamiento en "El Imparcial", para cuyo efecto me parece que podríamos comenzar publicando un artículo especial que Ud. quisiera enviarme y que sería de suma eficacia.
Le reitero que aquí hay varios interesados en "Amauta". Tal vez podrían colocarse algunas suscripciones. Conviene, por lo tanto que se moleste en mandarme algunos ejemplares.
Aguarda su palabra alentadora.
Luis Rodrigo
Enviole algunos comentarios hechos por mí al galope. Aquí la vida no da tregua para meditar; pero sea como fuere, los anima un pensamiento central, la defensa de nuestra raza y nuestros pueblos.

Transcripción completa (se ha respetado la grafía del original):
A bordo del "Atenas", 18 de octubre 1919 Ruth:
Desde mi partida del Callao pensé que te debía unas palabras de adiós. Recordé que tu eras una de las personas que habían sido buenas y dulces conmigo y recordé, sobre todo, nuestra original y simpática intimidad de un tiempo.
Estas líneas, escritas a bordo del “Atenas”, en viaje a New York, te llevarán mi despedida. Me despido en ti de todas las muchachas de Lima que alguna vez se han emocionado leyendo algo mío. Seguramente eres tú la más sentimental, soñadora y tierna de todas.
Compara mi letra de ahora con la de antes si alguna carta mía, merecedora de inmediata inhumación naturalmente, sobrevive entre tus recuerdos. ¿Habrá envejecido mi letra como mi alma? ¡Ah! Ten en seria consideración caligráfica el balance del "Atenas” y la turbulencia célebre del Caribbean Sea.
Si alguna vez te sobran tiempo, humor y sentimentalismo, escríbeme a Roma.
Tu affmo amigo
José Carlos

A Ruth.
