the plots yielded in 1901 at the rate of 40 bushels per acre.
In 1900 this variety yielded at the rate of 35}é bushels per ·
acre.
Two other varieties grown in the plots are too late for the
production of seed, but in 1900 were favored by a prolonged
open fall, and mature seeds were secured from both. One of
these (No. 4914, U. S. Dep. Agr.) produced seeds at the rate
of 3423 bushels per acre, while the other (Seed bought of
]. M. Thorburn & Co.) yielded only 20}é bushels per acre.
Both of these late varieties would make good hay or silage.
Two plots of 4914 were cut in 1901, and yielded green fod-
der at the rate, respectively, of 14.08 and 11.8;]. tons per `acre,
and dry fodder at the rates of 6.16 and 5.4.4 tons per acre.
They were cut (Sep. 18) when pretty well matured, hence
W the yield is greater than can be expected in field work, where
the plants are commonly cut when in bloom. _
[ts mine zzsfvrage. The readiness with which stock of all
kinds eats the soy bean, fed as green fodder, as silage, or as
hay, is good evidence concerning its food value. Barring
cases of perverted appetite, animals prefer for food that which
affords them most nourisl1ment. Chemical analysis, while
admitted not to be the final test, strongly co11firn1s evidence of
other sorts. It shows that the plant contains a somewhat
higher percentage of the materials that produce muscle and
fat than does the cowpea. Actual feeding tests made so as to
_ exclude as far as possible chances of error, show that soy
beans are a nourishing food. Professors Voorhees and Lane,
of the New jersey Station, give the following as the result of
tests of soy beans and cowpeas :
DIGESTIBLE FOOD PER TON.
Fat, lbs. Protein, lbs. Carbohydrates, lbs.
Soy beans 6.6 34.2 174.0
Cowpeas 6.0 28.8 119.0

hand as a basis for comparison, it may still be said without
danger of going far wrong that soy beans have the same effect _
as a green fertilizer as cowpeas.
