Mammoth Clover. — This variety was cut on ^Tune 23, at 

 which time it was not in full bloom. It was thought best 

 to harvest, as it was lodging badly. On August 10 it was 

 cut for the second time. It did not make sufficient growth 

 thereafter to warrant cutting again. Though cut, therefore, 

 but twice, while the common red clover was cut three times, 

 the mammoth clover produced slightly more hay than the 

 former. The two crops make a yield at the rate of rather 

 more than 4J tons per acre. This hay is not objectionalily 

 coarse, or, rather, not much more so than that of the com- 

 mon red variety. This mammoth clover, as will be seen by 

 reference to the table below showing composition of the 

 crops, is not inferior in nutritive value to the common. 

 The mammoth is to be especially recommended for sowing 

 in mixtures of which timothy is a prominent part, as it 

 matures more nearly with this grass than does the common 

 red. 



Common red clover calls for little special comment. Each 

 of the three cuttings was made when the crop was a little 

 past full bloom ; the dates, June 19, July 28 and October 9. 

 The average total yield of the plats (one-tenth of an acre 

 each) is at the rate of a little more than 4^ tons per acre. 

 The composition of this variety will be found in the table 

 which follows those showing yield and dry matter. 



Alsike clover guve two excellent crops, cut respectively on 

 June 19 and August 10 : but, while the sod of both the 

 mammoth and common red on November 3 appeared to 

 be in excellent condition, the sod of this variety shows 

 signs of weakness. Weeds are coming in to a considerable 

 extent, principally sorrel. The table of composition shows 

 this clover to be somewhat richer in nitrogenous nutrients 

 (protein) than either of the others. This difference in its 

 favor is in part offset l)y lower percentages of fat and ex- 

 tract, and it is doubtful whether the hay of this variety 

 is worth more for food than that of either of the others. 

 Alsike clover is especially recommended for soils which are 

 rather too moist for the common red variety.
