At a time when I was already overloaded, the death of dear Torrey has thrown some cares and extra work upon me. I have to carry through the press a report of his upon the plants collected in west North America, in Wilkes’s Expedition, which was drawn up, but never really finished, twelve years ago, and was called for just during Torrey’s last sickness, and to his annoyance, which I felt bound to relieve as well as I could. Then, six weeks or more ago, died my next oldest friend and companion, Sullivant, making a sad spring and giving me a needed warning to make haste. He again leaves two unfinished works which I must see to, though Lesquereux will, I trust, edit them. Of one, indeed, he was to be joint author. The other, a second volume of the beautiful “Icones Muscorum,” is ready as to the plates, but not at all so, I learn, for the letterpress. For myself, as I think I have already told you, this summer completing thirty-one years of professorial work in the university, I am relieved from further duties of instruction,--and of my salary. I shall not experience the full relief until the very close of summer. For, in the interest of this department of the university, and to leave it in proper working condition, I have undertaken a course of what we call university lectures,--meaning lectures intended the rather for others than members of the university,--and have opened the botanical laboratory to pupils, mainly teachers in schools, for the summer.[93] Considerable time must be given to them, but, after a few weeks, I hope to throw it mainly upon my assistant, Professor Goodale. Professor Goodale, under appointment as assistant professor of vegetable physiology, will take the whole work of instruction in botany off my hands; but if a former assistant and pupil, Dr. Farlow, now with De Bary, proves capable of it, as I hope, he will, I trust, take up the work in systematic botany. His fancy, however, is for Cryptogamia. Mr. Sereno Watson is the only one here to do work in systematic botany, but he will not teach. He and I are endeavoring to help out Professor Brewer in the “Flora of California,” which, to be done at all, must be pushed through at once. I have promised to do the Gamopetalæ, which come in the field I am striving to cover for the “Flora of North America.” That work I hope now to give myself to. I ought to have taken this step several years ago; but I could not afford it, and it is only now that I have been able to bring the department here into the position in which I feel justified in resigning the care of it. I retain the charge of the herbarium, and I continue my residence in the house which is connected with it. Dr. Torrey’s herbarium and library were made over to Columbia College, and will be kept up, although no professor will be appointed at present. Mr. Sullivant’s bryological collections and library are to come here.
