Period III.—This period began December 11 at noon and closed 
December 24 at noon. Only two lots, I and II, were under experimen¬ 
tation. The object during this period was to find the approximate value 
of the entire pumpkin as a succulent and the ground “cannery” seeds 
as a concentrate in the ration for young growing pigs. During this 
period lot I received chopped pumpkin (containing 10.65 P er cent seeds), 
fed by hand, and a known amount of ground “cannery” seeds mixed 
with the middlings of the self-feeder ad libitum. Lot II was 011 the self- 
feeder only, thus serving as a control. 
Tables XVII to XIX show the results obtained during period III.

During the first week of period III no marked difference in gain and 
consumption of food per 100 pounds live weight took place. However, 
during the second week of this period lot I gained four times more 
weight per hundredweight, consuming a little more of each ingredient. 
Period IV.— This period is practically a continuation of the preced¬ 
ing period except for the elimination of pumpkins from the ration. The 
ground “cannery” seeds were mixed with the middlings and placed in 
the self-feeder from which the pigs could get it ad libitum! The object
