RELATIVE YIELDS OF DIFFERENT PLATS. 



While conclusions cannot be drawn from a single season's 

 work, a comparison of the yields and of the different lots is of 

 interest. As already stated, one plat from every lot of seed was 

 cut at the time the earliest plats — which happened to be Num- 

 bers 17 and 19 — were ready for harvest. The duplicate plats 

 were cut as they matured or, in a few cases, at the end of the 

 season, to save them from destruction by rust. 



The preceding tables give the results in detail. 



The largest yields were obtained, in the order given, from 

 plats with seed from Minnesota, Bohemia, Indiana, Wisconsin, 

 Brittany and Ohio. 



The shrinkage in drying ranged from 68 per cent on plat 20 

 (Bohemia), to 82 per cent on plat 25 (Denmark). The mature 

 crop from Wisconsin and Minnesota plats each shrank 69 per 

 cent, and from Indiana 70 per cent. The usual shrinkage, how- 

 ever, was about 73 to 75 per cent. In considering weights and 

 shrinkages it should be borne in mind that green clover leaves are 

 more numerous and in the aggregate heavier than the mature 

 stalks, because of the greater amount of water contained. For 

 this reason the weight of the undried product of some plats, 

 which were late and very immature, appears greater than that 

 of other plats which were in every way superior ; the shrinkage 

 in drying is, however, correspondingly greater.
