BULLETIN 21, U. S. DEPARTMENT OF AGRICULTURE. 
A ration composed of about 1 part*of shorts, 2 of low-grade flour, 
and 3 of corn meal was fed until August 12, when it was changed to 1 
part of shorts, 1 of flour, and 2 of meal. On August 23 another change 
was made to 1 of shorts, 2 of flour, and 4 of meal, which was again 
changed on October 8 to 1 of shorts, 3 of flour, and 9 of meal, which 
was fed to the end of the season. The gains and cost were quite con- 
sistent, as the variation was due largely, if not entirely, to conditions 
other than feed. Chickens will use a larger per cent^of corn meal more 
efficiently during cool weather, as the feeding season progresses. 
These records- show a marked decrease in gams during the hot weather 
in August, and an extremely high cost of gains during November and 
December. The poor results obtained in August were due partly to 
overcrowding and perhaps partly to feeding a mixture which was too 
thick during the extremely hot weather.
