Table V. gives the lowest yield—491°5 lb. of milk for a consumption of 1,745 
Ib. of prickly pear ; while Table VI. shows a slightly increased yield over Table 
V.—namely, 495 lb. of milk for 2,683 lb. of pear. 
Comparing results, as shown in Tables I. and VI., it is found that 1,586 lb. 
of oaten chaff were consumed fora return of 559 lb. of milk, and 2,683 lb. of 
pear for a yield of 495 lb. of milk, or in the proportion of 2°83 Ib. of chaff or- 
5°42 Ib. of pear for every lb. of milk. The cows lost flesh when fed on the 
prickly pear alone. We do not look on the pear as a milk-producing fodder, 
and it is unlikely that it will be used asa stock food under conditions other 
than those of severe drought. 
The following sets of tables give the amount of food consumed and results 
obtained ; and are numbered from 1 to 6, each covering a period of five days :—
