“Mr. Carey was a man of marked gifts, accomplishments, and individuality. His name will long be remembered in American botany. There are few of his contemporaries in this country who have done more for it than he, although he took little part in independent publication. His critical knowledge and taste and his keen insight were most useful to me in my earlier days of botanical authorship. He wrote several valuable articles for the journals, and when, in 1848, my ‘Manual of Botany’ was produced, he contributed to it the two most difficult articles, that on the willows and that on the sedges.... “Being fondly attached to his memory, and almost the last survivor of the notable scientific circle which Mr. Carey adorned, I wish to pay this feeble tribute to the memory of a worthy botanist and a most genial, true-hearted, and good man.” It is to be regretted that Dr. Gray’s letters to his old friend are no longer in existence. His correspondence with Sir William Jackson Hooker, then professor at Glasgow, Scotland, began in 1835. TO JOHN TORREY. BRIDGEWATER, ONEIDA COUNTY, N.Y., January 1, 1831. DEAR SIR,--I received your letter, through Professor Hadley, a few weeks since, and I embrace the earliest opportunity of transmitting a few specimens of those plants of which you wished a further supply. I regret that the state of my herbarium will not admit of my sending as many specimens of each as I could wish or as would be desirable to you. I shall be able to obtain an additional supply of most of them during the ensuing summer, when it will give me pleasure to supply you with those, or any other interesting plants which I may meet with. I send you a few grasses; numbered; also a few mosses, etc. When you have leisure, you will oblige me by sending the names of those numbered, and rectify any errors in those labeled. If you should be desirous of additional specimens, please let me know it, and I will supply you in the course of next summer. You ask me whether I am desirous of obtaining the plants peculiar to New York, New Jersey, etc., or of European plants. I should be highly gratified by receiving any plants you think proper to send me; and will repay you, so far as in my power, by transmitting specimens of all the interesting plants I discover. I know little of exotic botany, having no foreign specimens. I am particularly attached to the study of the grasses, ferns, etc. If you have any specimens to transmit to me, please leave them with Mr. Franklin Brown, Attorney at Law, Inns of Court, Beekman Street, who will forward them to me by the earliest opportunity. During the next summer, I intend to visit the western part of this State, also Ohio and Michigan. I shall devote a large portion of my time to the collection of the plants of the places I visit. If you know of any interesting localities, or where any interesting plants could be procured, please inform me, and I will endeavor to obtain them for you. Respectfully yours, ASA GRAY.
