Accumulated collections, of Lemmon, Parish,[121] Cusick,[122] etc., especially have taken all my time up to now, after getting my home in order, a deal of trouble. And now I can think of getting at my “Flora” work again.

First of all, I am to make complete as I can my manuscript for Solidago and Aster. Solidago I always find rather hopeful. Aster, as to the Asteres genuini, is my utter despair! Still I can work my way through except for the Rocky Mountain Pacific species.

I will try them once more, though I see not how to limit species, and to describe specimens is endless and hopeless. So send on your things. But first I am to print, pari passu with my final elaboration, an article, “Studies in Solidago and Aster,”—taking the former first, giving an account of what I have made out in the old herbaria, stating investigations which I can only give the condensed result of in the “Flora,” etc. Considerable change as to some old species.

When I have done the Solidago, then Aster in that way....

TO A. DE CANDOLLE.

Cambridge, December 29, 1881.

I am doubtful if I have written to you since our return, and my New Year greetings will reach you somewhat late, but are very hearty. I could hardly have neglected to send you word of the satisfaction with which we look upon the fine bust of your father, which stands at one end of our herbarium; Robert Brown and William J. Hooker at the other, and your lithographic portrait overhead is replaced by the more striking photograph you gave us.

At length we are settled in our home; have had for the twenty-fifth time the annual Christmas family gathering, for which my study, being the largest room in the house, is always upturned and emptied, and I should be quietly at work upon the Compositæ, were it not for an attack of lumbago, that uncomfortable attendant of old age, which just now interferes with my activity, without actually laying me up.... We, Mr. Watson and I, are still much occupied with the distribution, and therefore in good part the study, of the recent collections which have accumulated here and are still coming in. Much valuable time do they consume. The most interesting are from Arizona, etc., near the Mexican frontier, among which those we have most to do with are by Lemmon and by Pringle.[123] The former, I know,—and I shall soon know as to the latter,—has sets to dispose of, and I think you would like to have them. We formerly have taken a deal of trouble in assisting such collectors in the disposal of their plants offered for sale, but we are obliged now to leave aside such affairs, as they consume too much time.

I have no other botanical news for you. Dr. Engelmann, who of late has roamed a good deal, is now at home, and busy with botanical work, of various sorts, Isoetes, Cupressus, etc. It is quite probable that he will cross the ocean again next spring, in which case you will probably see him. Professor Sargent is busy with his forest reports in connection with the United States Census of 1880. Mr. Watson in this service made a long journey through our northwest region, while I was in Europe, at too late a season for much ordinary botany; and he has been otherwise too busy since his return even to look over his collections.

My colleague, Professor Goodale, giving over to Professor Farlow the university lectures, etc., is now abroad with his whole family, to recruit health and acquire information. You will see him at Geneva in spring or summer, and I commend him to you as a dear friend and a very valuable man. My wife joins me in kind remembrances and best New Year wishes to Madame De Candolle and yourself, and I am always your devoted
