Mr. Walter Deane, 



29 Brewster Street, 

 Cambridge, Mas3. 



Dear Mr. Deane: 



I am trying to "build up a small private herbarium of my 

 pet family the Compositae, and it occurred to me that you might have 

 duplicate specimens of my desiderata which you would be willing to exchange 

 for D. C. things. I expect that you have just about everything in 

 Gray's Manual but there may be some few things I could supply. 

 I enclose my own list on a separate sheet and should be very grate- 

 ful for any of these you could send me. 1 do not believe that I 

 nave a single plant from you in my herbarium. 



I was much interested in your paper on your Cambridge 

 salt marsh. Your foresight in listing the flora of this place so 

 many years ago is certainly repaid now. Your work on this marsh 

 seems to me a real contribution to ecology. 



I observed by reference to American Men of Science that 

 your 78th birthday had come a few days ago. Please accept my some- 

 what belated congratulations. 



Very truly yours, 



Associate Botanist.
