Mr. Walter Deane, 



29 Brewster Street, 



Cambridge, Massachusetts. 



My dear Mr. Deane: 



You will be interested to learn, I am quite 



sure, that I have asked for a furlough from the Rational Mu- 

 semn and have been transferred to the Carnegie Institution, 

 and have already begun my work of preparing an exhaustive mono- 

 graph on the Cactaceae of North and South America, It is with " 

 considerable regret that I sever my relations with the National 

 Museum, with which I have been connected for so long; but the 

 offer of the Carnegie Institution opens up so many possibilities 

 that I could not very well decline it. The enclosed letter will 

 show you the scope of my work. 



As you are aware, only one cactus is to be found in all New 

 England. Would it be too much trouble for you to give me the 

 records, so far as you know, for Opuntia in New England, and what 

 localities for the plant in Eastern United States are shovm by 

 your herbarium specimens? 



Yours very truly. 



Research Associate.
