divide this sum by the protein. What is the nutritive ratio of buck- 
wheat, containing 8.1 per cent of digestible protein, 48.2 per cent of 
digestible carbohydrates and 2.4 per cent of digestible fat?

9. Make a list of feeds used on your father's farm. Consult 
appendix for digestible nutrients and determine nutritive ratio of 
each. 
10. Determine the nutritive ratio of each feeding standard given 
in paragraph 11 on page 60. 
41. Amount or FEEp.—Require pupils to make measurements of 
the home storage places. 
1. Corn in crib—Multiply together the height, width and length 
in feed and multiply this product by 0.45 for old corn, and by 0.4 for 
new corn. The final product will approximate the number of bushels 
of corn in the crib. 
Problems: (a) How many bushels of new corn in a crib 20 feet 
long, 4 feet wide and 10 feet high? 
(b) What is the approximate amount of old corn in 
a crib 30 feet long, 12 feet high and 4 feet 
wide? 
2. Hay in mow—Multiply together the height, length and width 
in yards and divide by 15 if the hay be well packed. If the mow be 
shallow and the hay recently placed therein, divide by 18, or by any 
number from 15 to 18, depending upon the character of the packing. 
This gives approximately the number of tons. 
Problems: (a2) How many tons in a mow 46 feet long, 18 feet 
high and 35 feet wide, the hay being just 
put in?
