least enough of the plants survived to furnish seed for future sow- 

 ings, and in 1867, 480 pounds were threshed from three acres and 

 sold in Minneapolis. 



In after years it seems that Mr. Grimm's neighbors attempted to 

 grow alfalfa with common seed produced in other states, but in 

 nearly every case the stands winterkilled, while the fields of Grimm 

 were not injured. The attention of the Minnesota station was

called to this alfalfa in 1901, and by careful experimentation Grimm 

 alfalfa was found to be far superior to common kinds to withstand 

 unfavorable winters. Since then its growth has been widely ex- 

 tended in the alfalfa-seed-producing states of the West, but even 

 now the Grimm seed is high priced and it is rather hard to get the 

 genuine article. 



Origin of Baltic and Cossack 



The Baltic alfalfa originated near the little town of Baltic, South 

 Dakota, and is very similar to the Grimm. 



The much-advertised Cossack alfalfa was procured in 1 907 by the 

 United States Department of Agriculture from Russia. It has a 

 more widely variegated flower than Grimm, but there is no evidence 

 that it is superior in yields or hardiness in the humid states to Grimm 

 or Baltic.
