highly proteinaceous substance, or whether it is grown on the 

 farm, the result in feeding is the same. 



The following experiment was conducted at the South 

 Dakota Experiment Station during September and October, 

 1908 and 1909. Each year forty-eight. (48) head of lambs 

 were purchased, divided into four different lots of twelve (12) 

 head each, and weighed up for the test. Each lot was pro- 

 vided with a small house for shelter in case of storm. Lot 

 I received rape pasture alone, Lot 2 received rape pasture and 

 shelled corn, Lot 3 received rape pasture and oats, and Lot 

 4 received rape pasture and barley. With the exception of 

 Lot I, each lot was given what grain it would eat up clean. 

 The first test extended over a period of forty-four days, and 

 the second test covered a period of thirty-one days. On ac- 

 count of the dry weather and early killing frosts in 1909, 

 which stopped the growth of rape, it was impossible to cover 

 the same number of days as in 1908. 



'For this reason the results of our second year's work are 

 not so good as they are for the first year.
