Dear Sir:- 
Fcr several years Mrs. Chase and myself have been en¬ 
gaged upon a monograph of the North American Species of Panicum. 
The work is now at a stage where we can utilize material from 
other herbaria, and we shall be pleased to examine and identify 
collections of Panicum sent in to us. We wish particularly local 
collections as we hope through these to extend our knowledge con¬ 
cerning distribution. We hope to return at least the section Di- 
chotoma by May 1st or probably at an earlier date. Packages for 
identification should be sent to A. S. Hitchcock, Dept, of Agri¬ 
culture, Washington, D. C. 
Very truly
