 My Dear Dr. Torrey


 Yours of last Friday is 
 received. I am not doing 
 much (towards the Californian 
 Botany just now, because of 
 College duties, but expect 
 to be at work in a few weeks 
 more. The remainder of 
 this year, I expect to devote 
 a part of my time to this 
 work and a part to my
 College duties. Next year I 
 purpose to devote the entire 
 year to finishing the botany,
 and any and all help I can
