New York, May 30, 1840.
I have been tolerably industrious for some years, but have never labored as I have done this winter and spring. But I look now for a little respite, which I greatly need. I have this afternoon written the description of the last plant we have to give in the 1st volume of the “Flora” (a new cucurbitaceous genus, of which more anon); have prepared the last sheet for the press,—that is, of the work proper, which reaches to page 656 instead of 550, as intended; and have before me proofs of the supplement extending to page 672; what is yet to come will make up the volume to 720 pages! It has extended beyond all calculations or bounds, but we could not stop short. I hope to have done with the proofs early next week, when I expect to go immediately into the country and recruit for three or four weeks, for I am quite fagged out. Except, however, mere fatigue and the usual consequences of loss of rest, I was never, perhaps, more perfectly in health, and a fortnight or so of botanizing will restore my strength. You kindly inquire about my plans and prospects. These are so far favorable that they will give me (D. V.) another year of nearly undivided attention to the “Flora.” Not long since I was officially informed that the opening of our university would be postponed another year, on account of unfavorable times, and the preparations not being sufficiently advanced. So I am told that I can have my time nearly all to myself until next spring (1841) if I wish (which of course I do), but without any salary, which, indeed, I could not with any propriety take while I perform no duty. By very close economy I think I shall get on for the year to come, and be able to accomplish a good deal of botanical work. I am going to pay the Michigan people a visit, and if they make good their promises made to me a year ago, as I have reason to think they will, their course towards me will have been liberal and honorable. I have good reason to hope they will eventually succeed in their plans.
By the London packet of the 15th of June we hope to send you and other friends some copies of the “Flora,” parts 3 and 4. There are so many errors, so much bad printing, and so many things that we could now do much better, that I regret that any portion was published before my visit to Europe. Many of the most important corrections are given with additions, etc., in a supplement, but I hope we shall continue to improve as we go on. We can work to much greater advantage than before, from being much better supplied with books, as well as with specimens and information. Yet often do I wish to be within reach of your herbarium and library. Long accustomed to these advantages, you can scarcely appreciate the difficulties we often find. I was to-day wishing for a look at your Cucurbitaceæ; we have, as you know, but few of the order.
I shall not be able to visit Florida or any part of the Southern States this summer; indeed, I fear I shall be debarred from any botanical journeys for some years. I must direct all my time and strength to our “Flora.” I hope we may complete another volume by the spring of next year. The way seems to be opening for increased facilities in sending a botanical collector to the Rocky Mountains. Our government is about to establish a line of military outposts quite up to the source of the Platte, in the principal pass of the mountains; and in a few years I doubt not we shall have small colonies in Oregon; but I know not when we shall be able to send a collector. I would like vastly to go after Grayia myself, but that cannot be at present. Nuttall has been giving a course of botanical lectures in Boston; and still remains there, I believe. My attempts to find Wilson’s poem have not yet been successful. I shall esteem it a piece of good fortune if I succeed. I have engaged a friend of mine, a bookseller, also to search for it; and when I visit Philadelphia I shall inquire of some old people who knew Wilson. May God bless you, my dear friend; kindest, regards and affectionate sympathies to Lady Hooker.
Faithfully your attached,
A. Gray.

New York, September 15, 1840.
My dear Friend.... I had not forgotten our conversation on the subject of geographical botany. On my return I found I had a copy, a mere proof, of the little article I spoke of, and was about to offer it to you, but on examination it appeared to me much less important than I had supposed and perhaps led you to expect. But as it may be of some little use, I now beg you to accept it. I have added, here and there, the scientific names when the popular names only were mentioned.
The question you suggest as to the effect of the destruction of the forests on the climate is very interesting, and I think still unanswered. I fear it will be next to impossible to obtain data, even in this country, for its satisfactory determination. There are very few thermometrical observations on record of sufficient extent or exactness, except for the last eight or ten years. For a year or two I shall not be able to pay any attention to these subjects except to collect materials. But I am very desirous to afford you any aid in my power, and will attend to any suggestions you make, obtain any data which come in my way, or secure the services of our botanical correspondents scattered throughout our extended country. Pray tell me how I can aid you. The annual reports of the regents of the University of the State of New York are documents submitted annually to our legislature, and printed at their expense for public use. They relate chiefly to the condition of our colleges and higher schools, but for six or perhaps nine years past have also embodied the results of the meteorological observations made throughout the State under their instructions. The “Reports” are not on sale, and the earlier numbers are not to be obtained except by some lucky chance....
