On May 2«>, at noon. I left Lincoln by the Burlington and Missouri 

 River Kailroad to spend three months in the Black Hills of South 

 Dakota. A few days before, I had received a commission from the 

 Tnited States Department of Agriculture as an agent of the Divisiou 

 of Botany for the purpose of making- an investigation of the flora of the 

 Black Hills. Up to July 3, I was accomi)anied by Mr. A. E. Wagner, 

 a graduate student of the I^niversity of Nebraska. In the morning of 

 ]\Iay 27 we arrived at Edgemont, where the railroad crosses the Chey- 

 enne Kiver. I availed myself of frequent opportunities to collect along 

 the railroad track. Arriving at Custer, which x)oint was taken as the 

 base of oi)erations, being about the center of the Hills, we remained 

 there until -lune 7, collecting in all directions from 4 to G miles from 

 town: but the number of plants in flower was not large. On July 7

 mountains not far from Harneys Peak. On June 10 we returned to
