COMPARISON OF CLOVER NO. 16 WITH OTHER STRAINS. 



An inspection of Table IX shows that clovers Nos. 16 and 17, 

 from Orel and Mogileff, respectively, were the heaviest producers 

 of green matter, the yield of the latter being the greater. In this 

 connection it should be noted that No. 17 was harvested after coming 

 almost into full bloom, while No. 16, according to notes taken on 

 the date of cutting, had practically^ no blossoms. From this it seems 

 probable that the Orel clover was harvested fully two weeks before 

 it had reached the same state of maturity that had been attained 

 by the other strains. Despite this fact it was outranked in yield 

 only by the strain from Mogileff, which lacked but two days of being 

 in full bloom. There can be no doubt that the Orel strain would 

 have given a yield of several thousand pounds more to the acre 

 had it been allowed to reach the stage of maturity at which it is 

 customary to cut clover for hay. 



The Orel clover exhibited the same fineness of texture, absence 

 of hairiness, erect habit of growth, succulence, etc., that were ob- 

 served on the plats in Nebraska and South Dakota. These qualities
