part of the laying season. Lots XIX and XX were alike at the 
start, containing equal numbers of two-year-old Wyandotte hens. 
Lots XVII and XVIII contained equal numbers of Leghorn pul- 
lets. The pullets in Lot XVII had been fed from the day they 
were hatched a ration which contained a large proportion of an- 
imal food, while those in Lot XVIII had been grown on a ration 
of vegetable food supplemented by some skim milk curd. Some 
of the pullets in both lots had been laying for some time before 
this experiment began but those in Lot XVII had commenced 
laying several weeks younger than those in Lot XVIII. The 
hens in the other two lots had been treated alike until used in 
this experiment. Lots XVII and XIX were fed the ration con- 
taining animal meal described on page 77 and Lots XVIII and 
XX were fed the contrasted ration. 
The accompanying tables give the data averaged for periods 
generally of four weeks.
