Dear Irof. Collins, 
On Eovember 15th I sent to you, in four 
parcels, 278 sheets of "botanical specimens and have never 
heard whether they were received or not. I suppose they 
reached you at a time when yon were "busy with university 
work. I am writing now to say that the grasses were named 
"by Hitchcock, or one of his assistants, and his names were 
put on the duplicate specimens without any study having 
"been given them, and some of them I have since found to "be 
incorrectly named, Oryzopsis bloomeri, for example, and 
some of the loas..

Very truly.yours,
