each plat was on the hmd iu which pea vines had been plowed, and the 

 other half on the part that had lain idle during the summer, a space of 

 10 feet being left between the two halves. TIio plats were one twenty- 

 fifth of an acre each. They were sown to wheat (a mixture of Fnltz 

 and Fnlcastcr varieties), November 13, 1888, at the rate of one half 

 bushel per acre. Just before seeding, fertilizers, as indicated in the 

 table below, were applied to five of the plats, two remaining unmannred. 

 Thus the two halves of each plat were treated exactly'- alike except that 

 one half had pea vines and the other had none. The following table 

 gives the amount and cost of the fertilizers applied, and the yields of 

 grain on bolh halves of each plat, calculated for one acre.

The average increased yield where pea vines had been plowed in was, 

 therefore, 10 bushels of wheiit per acre. " One single experiment does 

 not prove a truth. In the fall of 1889 this experiment was repeated, 

 and probably will be continued several years. In view of these facts, 

 it will be better to wait till the series of experiments have been finished 

 before farther conclusions be presented."

Comparative digestibility of cooled and uncooked silage. — The experi- 

 ment was made to determine the comparative digestibility of cooked 

 and uncooked corn silage when fe<l to sheep. The silage used ^vas 

 made from an overripe dent corn and "was iu first class condition " 

 when fed. One Shropshire wether was used for the trial. The animal 

 was fed for a time on uncooked silage, and then, in a transition period, 

 changed to cooked silage. The lengths of the feeding and transition 

 periods are not stated. For one week in the latter part of each trial 

 the excrement was collected, weighed, and analyzed. An analysis of 

 the silage used is given. Determinations of dry matter in the silage 

 offered and rejected were made each day.
