Your letter of the 13th ult., with the bundle of books, was in due time received. Yours of the 2d ult. was received at the same time. I can send you no more copies of “Gramineæ,”[28] etc.; all I brought up are subscribed for and delivered. “Major Downing,” who subscribes for two copies (one for himself and one for his friend the Gin’ral,[29] I suppose), as well as the other subscribers, must wait until fall. I am lecturing here to a small but quite intelligent Senior class, twenty-six in number, just enough to fill three sides of a large table, and time passes very pleasantly. The small fund for the support of this institution will, I think, be secured, but the trustees do not act in concert with the faculty, and it is rumored quarrel among themselves, so that, unless some changes are effected in the board, I fear the college will not be sustained. I shall remain here five weeks longer, and then have a short engagement at Utica. I have promised to make a visit to the north in August. I wish very much that I was able to remain there six or seven weeks, to examine with attention the vegetation of the primitive region in St. Lawrence and Franklin counties. I cannot doubt that the mountains and the banks of the large streams of that region would furnish a rich harvest of plants. That range is an extension of one from the far north, which, passing between the Great Lakes and Hudson’s Bay, crosses the St. Lawrence at the Thousand Islands, and passes through St. Lawrence, Franklin, and Clinton counties. Consequently many sub-alpine plants, such as Anemone Hudsonica, Trisetum molle, Geum triflorum, etc., are found in this region farther south than elsewhere. The mineralogy of the region, also, needs to be farther explored. The expense of such a tour, divided between Dr. Crawe and myself, traveling in a conveyance of our own, will be comparatively trifling.
