material, I am only interested in herbarium specimens of 
useful (eoonomio) plants. 
I have not heardffrom Ur. Sohleohter for over a month. 
As replies to some of ray letters to him were really very 
necessary, I am beginning to feel troubled. 
I have an interesting paper with plates on the way 
through the press. A oopy of this will be sefct to you on the 
day of publication. 
A package of genus covers has been sent off. If you 
need anything else, inform me of your needs when you write 
again. 
Yours faithfully,
