158 AGRICULTURAL EXPERIMENT STATION. [Jan. 



1889. — The general appearance of the plats seeded down 

 in preceding years with perennial varieties of grasses and of 

 leguminons plants presented some interesting features at 

 the opening of the late season. Some crops had sufiered 

 seriously from winter-killing, while others had passed 

 unharmed through the winter. Wherever the growth had 

 suffered, the fact showed itself invariably in the most serious 

 degree upon unfertilized plats. 



Kentucky blue-grass, Plat 11 (fertilized), was well pre- 

 served; the same' circumstance was noticed on Plat 12 

 (unfertilized) . 



Perennial rye-grass, plats 13 and 14 (fertilized and 

 unfertilized), Avas dead in the rows. 



Italian rye-grass was fairly preserved in the rows on both 

 plats. 



Meadow fescue. Plat 17 (fertilized), was in a healthy and 

 well-preserved condition. 



Alsike clover, plats 18 and 19 (unfertilized and fertilized), 

 had suffered somewhat on the unfertilized plat, but was well 

 preserved upon the fertilized plat (19). 



Medium red clover, raised on the same plats as the alsike, 

 was in better condition upon the unfertilized plat (18) than 

 the latter, yet fell behind on the fertilized plat (19). 



Alfalfa, plats 20 and 21 (unfertilized and fertilized), was 

 almost entirely winter-killed. The same feature was notice- 

 able in regard to mammoth red clover, upon the unfertilized 

 Plat 20, while upon Plat 21 (fertilized) a ftiir growth was 

 noticed. The plats 15 and 16, which had been used in the 

 preceding season for the production of Soja beans, were 

 ploughed and prepared for seeding ; the same course was 

 pursued in regard to the grass and clover plats, where the 

 growth had been seriously winter-killed, — plats 18, 20 

 and 21. 



Plats 12, 14, 16, 18 and 20, which for five preceding 

 years had not been fertilized, were treated, like all fertilized 

 plats in this field, with eighty p'ounds of fine-ground bones 

 and twenty-seven pounds of muriate of potash per acre. 



Plats 15 and 16 were turned to account for the cultivation 

 of Bokhara clover (Melilotus alba) and of sainfoin (Onobry- 

 chis sativa). Each plat was subdivided into two equal
