Andes. It is quite unknown; the Indians tell us it is two or three hundred yards broad, and horses can nowhere ford it. I cannot imagine anything more interesting. Our plans then are to go to Fort Famine, and there we meet the "Adventure", who is employed in making the Chart of the Falklands. This will be in the middle of winter, so I shall see Tierra del Fuego in her white drapery. We leave the straits to enter the Pacific by the Barbara Channel, one very little known, and which passes close to the foot of Mount Sarmiento (the highest mountain in the south, excepting Mt.!! Darwin!!). We then shall scud away for Concepcion in Chili. I believe the ship must once again steer southward, but if any one catches me there again, I will give him leave to hang me up as a scarecrow for all future naturalists. I long to be at work in the Cordilleras, the geology of this side, which I understand pretty well is so intimately connected with periods of violence in that great chain of mountains. The future is, indeed, to me a brilliant prospect. You say its very brilliancy frightens you; but really I am very careful; I may mention as a proof, in all my rambles I have never had any one accident or scrape...Continue in your good custom of writing plenty of gossip; I much like hearing all about all things. Remember me most kindly to Uncle Jos, and to all the Wedgwoods. Tell Charlotte (their married names sound downright unnatural) I should like to have written to her, to have told her how well everything is going on; but it would only have been a transcript of this letter, and I have a host of animals at this minute surrounding me which all require embalming and numbering. I have not forgotten the comfort I received that day at Maer, when my mind was like a swinging pendulum. Give my best love to my father. I hope he will forgive all my extravagance, but not as a Christian, for then I suppose he would send me no more money.
Good-bye, dear, to you, and all your goodly sisterhood.
Your affectionate brother, CHAS. DARWIN.
