Dear Sir: 



We are sending you herewith a small package of grasses 

 with as many of your desiderata as we can supply. With Pro- 

 fessor Hitchcock's consent I raided the herbarium for dupli- 

 cates for you with the result that I was able to check off 

 all the Panicums wanted. I shall keep your list in the 

 hope of crossing off others from time to tire. 



This is a small return for your fine sets of Panicum. 

 I wish your wants were more numerous. 



Yours respectfully, 



Scientific Assistant in Systematic 



Agrostology.
