How I wish you could have been of the party! We dream of doing some parts again, and of going both farther south and north, three years hence. You and Sir Joseph would not then be too old. But I can hardly expect then to be, as last summer, one of the most active and frisky members of the party. Moreover, the cost in time is more than one counts on. From the middle of July to the end of September, one may, once in a way, fairly devote to holidaying. But then, after a week or two of work with Hooker over our notes and collections, I had to bring up long arrears, which I should have kept in hand if I had stayed at home, and so I have only now of late come to take up my regular work where I left it in July. If you do not hear enough of our summer’s doings from Hooker,--and I know he must be busy indeed,--we must get Mrs. Gray to write a narrative; not that she is not also a busy soul. All this time you have had anxious events to occupy your minds, and these are not yet over. But at home you are happy in the recovering health of your daughter after so long suffering. We had our usual Christmas gathering last evening, and the house is only now set to rights again. Your old friends Miss P. and K. L. were with us, and we spoke of you. The latter told us that Miss S. proposes to come to us from the West Indies, I suppose in early summer, and glad we shall be to see her. You never sent me your Middle Ages book; the publishers’ fault, no doubt, which I beg you will urge them to make up for.... TO GEORGE ENGELMANN. RIGHT May 20, 1878. ... That enlarged photograph[105] is for you, to be left for your St. Louis Academy of Sciences, if it ever gets a home, or for the Hortus Botanicus Missouriensis, as you elect. Glad you value it. I am at new edition of the “Structural Botany,” as a bit of ad interim work. TO A. DE CANDOLLE. CAMBRIDGE, June 9, 1878. MY DEAR COLLEAGUE: ... A copy of the second part of the “Synoptical Flora of North America” should soon reach you, for I was assured at Washington that they were sent at once, and would go to you without delay. If the “Revue Scientifique de Genève” takes book notices, I shall be pleased if you will notice this publication of mine. I send it to you, and to Boissier; also to Maximowicz of St. Petersburg, but to no one else on the Continent. It is put on sale with Trübner & Company, London, and T. O. Weigel, Leipsic. I have defrayed the whole cost out of my own purse, to the tune of $2,050. No publisher would take it, and assume the expense, so I have to carry it myself and botanists must buy it, if they want it. I hope many botanists and libraries will do so; for I must get the outlay back again, or a good part of it, before I go on. Hence, notices in the scientific journals and elsewhere may be serviceable to me. I will not speak of or count the time and hard labor I have bestowed on the work.
