agrainration. A few flockmasters feed both roots and grain. There 
are no silos on the project at present, but elsewhere in southern Idaho 
corn silage is fed to the breeding flocks with excellent results. Asit is 
popularly believed that the excessive feeding of roots may result in the 
preductin of soft, flabby lambs, the quantity of roots fed during the 
winter is not large, from 2 to 4 pounds per sheep being the daily allow- 
ance. Roots commonly are fed whole and im the field, as illustrated 
in figure 4. In some instances where grain is used, grain feeding begins 
a month or six weeks before lambing. Other flockmasters do not 
feed grain until after lambing time. There is, perhaps, no better 
grain ration to supplement alfalfa than a mixture consisting of two 
parts oats and one part bran. . A half pound to a pound of this mix- 
ture per head each day is sufficient. Unthrashed sheaf oats is a popu- 
lar and desirable feed to use in connection with alfalfa. The practice 
of feeding some supplement with alfalfa is rapidly gaining in popu- 
larity. Where such feeding is not practiced, it is frequently found 
that young ewes refuse to own their lambs and that neither young 
nor old ewes produce sufficient milk to feed the lambs properly. It 
is Important to provide the flock with fresh water and salt at all 
times. The practice of forcing the flocks to drmk from stagnant 
ponds or dirty drinking troughs is to be condemned. 
BUILDINGS AND EQUIPMENT. 
Except at lambing time, shelter is not absolutely necessary, 
although open sheds and windbreaks are desirable, as there is need 
for protection against west winds. A dry yard with an open shed 
or windbreak or with an open shed and a closed Jambing shed joined
