HERBARIUM OF HARVARD UNIVERSITY, CAMBRIDGE, MASS., November 19, 1885. HANG _To J. C. Arthur, C. R. Barnes, J. M. Coulter, Committee, and to the numerous Botanical Brotherhood represented by them_: As I am quite unable to convey to you in words any adequate idea of the gratification I received on the morning of the 18th inst., from the wealth of congratulations and expressions of esteem and affection, which welcomed my seventy-fifth birthday, I can do no more than render to each and all my heartiest thanks. Among fellow-botanists, more pleasantly connected than in any other pursuit by mutual giving and receiving, some recognition of a rather uncommon anniversary might naturally be expected. But this full flow of benediction, from the whole length and breadth of the land whose flora is a common study and a common delight, was as unexpected as it is touching and memorable. Equally so is the exquisite vase which accompanied the messages of congratulation and is to commemorate them, and upon which not a few of the flowers associated with may name or with my special studies are so deftly wrought by art, that of them one may almost say, “The art itself is nature.” The gift is gratefully received, and it will preserve the memory to those who come after us of a day made by you, dear brethren and sisters, a very happy one to Yours affectionately, ASA GRAY. TO S. M. J. November 19, 1885. We meant our day to have been most quiet, and I completely and J. largely were taken by surprise. So we had to send for two or three neighbors, especially to see the vase. J. will bring it in to you, no doubt, for she is very proud of it. The lines I have already written have taken all the strength out of my right arm, but not all the love out of my heart, of which a good share is yours. TO W. M. CANBY. CAMBRIDGE, November 19, 1885. MY DEAR CANBY,--Many thanks for your felicitations. There is much I want to write, and to say what a surprise we had, and how perfect the vase is. But my arm is worn out with note-writing. Yours affectionately, ASA GRAY. Two poems and a poetical epigram came among the rest! TO SIR EDWARD FRY. CAMBRIDGE, January 31, 1886.
