 of each variety the next year:

Professor IngersoU calls attention to the great differ- 

 ence in the yield of forage (cured hay) per acre in 

 the last column, varying from 1,015 pounds to 4,080, 

 the latter being for alfalfa, while the former was the 

 plat of mixed grasses. He further says: 



"Injustice to Plat 12 we will say that this was 

 located too near a row of well-grown cottonwood trees, 

 and thus, to some extent, robbed of plant-food and 

 moisture. But the comparison does not end here. The 

 alfalfa plat kept on growing by means of its deep roots, 

 and when in blossom was cut twice more. The other 

 plats made no aftergrowth worth mentioning. The 

 alfalfa crop then stood as follows for the second year : 



Hay, lbs. 



First cutting 816 



Second cutting 805 



Third cutting 743 



Fourth cutting (estimated) 180 



2.544
