JCT. 62.] TO W. M. CAN BY. 641 



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 Gamopetalse, 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. 



I send you by mail a copy of my biographical no- 

 tices of Torrey and Sullivant ; both from " American 

 Academy Council Report of Proceedings," and both 

 printed in advance, in " Silliman's Journal," where 

 you will see them. 



By the way, I have resigned the chair of the Amer- 

 ican Academy, after ten years' occupation, and it is 

 taken by Mr. Adams, whom you know. The third 

 class (classical and historical) takes its turn. 



TO W. M. CANBY. 



CAMBRIDGE, June 30, 1873. 



MY DEAR CANBY, My Diona3as grow finely, and 

 are the delight of my heart. 



Drosera longifolia, also cultivated, is almost as good 

 a fly-catcher. 



Now and then I see a little exudation inside base of
