1 Plus 350 pounds of barley and 600 pounds of milk. 
Table XX shows the results of 18 tests involving a total of 949 
pigs and a total area of about 50 acres. The number of pigs per 
lot ranged from 20 to 138, and the fields ranged in size from 1 acre 
to 9 acres. The gains per acre varied from 250 to 949 pounds. The 
average gain per acre of the 17 lots for which this was determined 
was a little less than 600 pounds. Of the eight tests in which the 
gains per acre were less than 600 pounds, six were on the Boise 
project; but some of the best gains were made on the same project. 
These facts indicate the wide variation to be expected in any given 
locality, depending upon the size of the pea crop in each field. The 
average daily gain per pig ranged from 0.54 pounds to 1.50 pounds. 
These gains naturally depend upon the abundance of the feed and 
the character of the pigs used. While the gains per acre of peas 
are not strictly comparable with those secured by hogging corn, be-. 
cause of differences in the location of the tests, it 1s of interest to ob- 
serve that the ranges in gains per acre of the two crops were not 
widely different. The range with corn without supplementary feeds 
was from 183 to 1,048 pounds: per acre, while that with peas was 
from 250 to 949 pounds per acre. 
The conditions under which these tests were conducted made it 
impossible to determine the values of supplementary feeds and the 
advantages of growing some small grain with the peas. There is 
nothing in these data to show whether or not a grain mixture or a 
supplementary feed is advantageous, This is a question which should
