The rotation may be worked out from the above planting 

 dates. Alfalfa should stand for five or six years. It is well to 

 sow a vining cowpea with late corn. More late corn might be 

 sown in place of barley and peas. Rape is palatable and is a» 

 heavy yielding crop (15 tons per acre). 



Table No. II gives in condensed form the yield in tons of 

 green and dry matter per acre in addition to the actual cost per 

 ton as fed.

Table No. 3 gives the results of one season's feeding ex- 

 periments with four cows which are fed on the previously de- 

 scribed soiling crops. As will be noticed from the table, the av- 

 erage cost per pound butter fat from the cows on the soiling 

 crops was 24.5 cents, and that of all the soiling crops, alfalfa 

 was by far the cheapest.
