But Geology carries the day: it is like the pleasure of gambling.
Speculating, on first arriving, what the rocks may be, I often mentally cry out 3 to 1 tertiary against primitive; but the latter have hitherto won all the bets. So much for the grand end of my voyage; in other respects things are equally flourishing. My life, when at sea, is so quiet, that to a person who can employ himself, nothing can be pleasanter; the beauty of the sky and brilliancy of the ocean together make a picture. But when on shore, and wandering in the sublime forests, surrounded by views more gorgeous than even Claude ever imagined, I enjoy a delight which none but those who have experienced it can understand. If it is to be done, it must be by studying Humboldt. At our ancient snug breakfasts, at Cambridge, Ilittle thought that the wide Atlantic would ever separate us; but it is a rare privilege that with the body, the feelings and memory are not divided.
On the contrary, the pleasantest scenes in my life, many of which have been in Cambridge, rise from the contrast of the present, the more vividly in my imagination. Do you think any diamond beetle will ever give me so much pleasure as our old friend crux major?...It is one of my most constant amusements to draw pictures of the past; and in them I often see you and poor little Fran. Oh, Lord, and then old Dash, poor thing! Do you recollect how you all tormented me about his beautiful tail?
...Think when you are picking insects off a hawthorn-hedge on a fine May day (wretchedly cold, I have no doubt), think of me collecting amongst pine-apples and orange-trees; whilst staining your fingers with dirty blackberries, think and be envious of ripe oranges. This is a proper piece of bravado, for I would walk through many a mile of sleet, snow, or rain to shake you by the hand. My dear old Fox, God bless you. Believe me, Yours affectionately, CHAS. DARWIN.
CHARLES DARWIN TO J.S. HENSLOW.
Rio de Janeiro, May 18, 1832.
My dear Henslow, ...
Till arriving at Teneriffe (we did not touch at Madeira) I was scarcely out of my hammock, and really suffered more than you can well imagine from such a cause. At Santa Cruz, whilst looking amongst the clouds for the Peak, and repeating to myself Humboldt's sublime descriptions, it was announced we must perform twelve days' strict quarantine. We had made a short passage, so "Up jib," and away for St. Jago. You will say all this sounds very bad, and so it was; but from that to the present time it has been nearly one scene of continual enjoyment. A net over the stern kept me at full work till we arrived at St. Jago. Here we spent three most delightful weeks. The geology was pre-eminently interesting, and I believe quite new;there are some facts on a large scale of upraised coast (which is an excellent epoch for all the volcanic rocks to date from), that would interest Mr. Lyell.
One great source of perplexity to me is an utter ignorance whether I note the right facts, and whether they are of sufficient importance to interest others. In the one thing collecting I cannot go wrong. St. Jago is singularly barren, and produces few plants or insects, so that my hammer was my usual companion, and in its company most delightful hours I spent.
On the coast I collected many marine animals, chiefly gasteropodous (Ithink some new). I examined pretty accurately a Caryopyllia, and, if my eyes are not bewitched, former descriptions have not the slightest resemblance to the animal. I took several specimens of an Octopus which possessed a most marvellous power of changing its colours, equalling any chameleon, and evidently accommodating the changes to the colour of the ground which it passed over. Yellowish green, dark brown, and red, were the prevailing colours; this fact appears to be new, as far as I can find out. Geology and the invertebrate animals will be my chief object of pursuit through the whole voyage.
We then sailed for Bahia, and touched at the rock of St. Paul. This is a serpentine formation. Is it not the only island in the Atlantic which is not volcanic? We likewise stayed a few hours at Fernando Noronha; a tremendous surf was running so that a boat was swamped, and the Captain would not wait. I find my life on board when we are on blue water most delightful, so very comfortable and quiet--it is almost impossible to be idle, and that for me is saying a good deal. Nobody could possibly be better fitted in every respect for collecting than I am; many cooks have not spoiled the broth this time. Mr. Brown's little hints about microscopes, etc., have been invaluable. I am well off in books, the 'Dictionnaire Classique' IS MOST USEFUL. If you should think of any thing or book that would be useful to me, if you would write one line, E. Darwin, Wyndham Club, St. James's Street, he will procure them, and send them with some other things to Monte Video, which for the next year will be my headquarters.
Touching at the Abrolhos, we arrived here on April 4th, when amongst others I received your most kind letter. You may rely on it during the evening Ithought of the many most happy hours I have spent with you in Cambridge. Iam now living at Botofogo, a village about a league from the city, and shall be able to remain a month longer. The "Beagle" has gone back to Bahia, and will pick me up on its return. There is a most important error in the longitude of South America, to settle which this second trip has been undertaken. Our chronometers, at least sixteen of them, are going superbly; none on record have ever gone at all like them.
