average of three tons of hay per acre. "Fields 

 twenty-five years old are still in good condition, but 

 continuous pasturing is detrimental, as it prevents 

 branching. Intermittent pasturing is not injurious." 



SOUTH DAKOTA 



Prof. James H. Shepard, direflor of the experiment 

 station at Brookings, saj's: "Alfalfa is not generally 

 grown in this state. There are some portions where 

 irrigation is pradliced that are raising fine crops. In 

 the Black Hills I have seen fine fields of irrigated 

 alfalfa, in the valleys, which gave from two to three 

 heavy crops per year. From one and a half to three 

 tons per acre has been obtained at each cutting. The 

 ordinary alfalfa does not seem to do well in the eastern 

 section of the state. The dry, cold weather of winter 

 seems fatal to the roots. We have great hopes, how- 

 ever, of the Turkestan alfalfa, which has given us very 

 good results in small plats, but we have been unable to 

 obtain sufficient seed to make large sowings. The 

 particular enemies of alfalfa are certain leaf-eating 

 insedls, like the spotted blister-beetle. These seem to 

 retard the growth by destroying the foliage. With 

 patience we hope to accomplish much in the near 

 future."

Andrew M. Soule, of the University of Tennessee, 

 at Knoxville, writes: " Having been in the state only 

 a year, I have not been able to inform myself fully 

 about all the soils and crops, alfalfa being one of the 

 crops. Thei-e is a great deal of contradidlory evidence 

 concefning its success. I notice a plot on the station
