July 15,1921 Effects of Some Cucurbita Seeds on Animal Metabolism 531 
Period III. Entire pumpkin and ground “cannery” seeds tested for 
their value. 
Period IV. Ground “cannery” seeds in a dry mash tested for their 
value. 
Period I.—This period began October 30 at noon and closed Novem¬ 
ber 27 at noon. The object during this period was to compare results 
obtained by feeding pumpkins from which the seeds have been removed 
with the results obtained by feeding the entire pumpkin. Lot I received 
during the first two weeks, besides the feed in the self-feeder ad libitum, 
finely chopped pumpkin containing 10.65 P er cent of seeds. During the 
last two weeks of this period the percentage of seeds in the pumpkin was 
increased to 21.30 by adding loose seeds. Lot II received the feed 
found in the self-feeder and served as a control. Lot III received, 
besides the feed in the self-feeder ad libitum, chopped pumpkin from 
which the seeds were removed. 
The results of this period are given in Tables XI to XIII.

Since a comparison of results obtained can be better made by figuring 
out the amount of nutrients required per pound of gain as well as the 
actual quantities of the different feeds consumed during a given period, 
these are given in Tables XII and XIII.
