For the roof, multiply the breadth at base of eaves by half the perpendicular 
height from eaves to ridge. 
17 X 3:5 = 59°5 square feet, area of roof. 
Add the two areas together, and multiply by the length of the stack, and we get 
the cubic content as follows :— 
188'5 + 59:5 = 248 x 50 = 12,400 cubic feet, 
or nearly 460 cubic yards. The hay in such a stack would weigh, PStuBee, 150 lb. 
per cubic yard (but this is a very variable quantity) ; hence, the total weight of hay 
would be about 243 to 25 tons. Ifit is a wheat stack, you may take a cubic yard to 
represent 1 bushel of grain. The stack should thresh out 460 bushels. But these 
weights are merely approximate, as both hay and grain vary largely in weight. 
To CatcunaTe THE Weicut or Hay 1n tue Stack. 
Hay, as I have said, necessarily varies in weight, according to quality, size of 
stack, age, &c. New hay may weigh 112 or 140 lb. When the stacks are ten or 
twelve months old, the cubic yard may weigh 14, 16, 18, and as much as 20 stones. 
Taking 140 1b. as the weight of a cubic yard, such a stack as I have described 
would contain 22,400 lb., or 10 tons. 
THE QUANTITY OF GRAIN IN THE STACK 
may be estimated at the average quantity of 1 bushel to the solid yard. ; but if the 
crop has been mown, a yard will not average more than three-quarters of a bushel. 
Stacks or Straw 
are reckoned, on an average, at the rate of 18 to 20 cubic yards to the ton. 
ContENnT oF SItos. 
A building 20 feet long, 12 feet broad, and 10 feet-high to the eaves, with an 
additional height of 6 feet from the eaves to the ridge, will contain 2,880 cubic feet. 
If all the dimensions of the building are doubled, it will hold 24,960 feet of silage. 
HOW TO MEASURE CORN IN THE BARN. 
The following rule will apply to a barn or crib of any kind :— 
Two cubic feet of sound dry corn in the cob will make a bushel of shelled grain. 
To get at the quantity of shelled grain in a crib of cobs, measure the dene 
breadth, and na of the crib. Multiply the length by the breadth, and the product 
by the height. ‘Then divide the product by 2, and you have the number of bushels in 
the crib. 
Exampus :—-Your crib or barn is 20 feet long, 10 feet broad, and 8 feet high. 
This is packed with husked corn— 
20 x 10 x 8 =1,600 cubic feet. 
Divide by 2, and you get 800, the number of bushels of shelled grain in your barn. 
Suppose you want to calculate 
THE NUMBER OF BUSHELS OF POTATOES IN A PIT. 
Multiply the length, breadth, and depth of the pit together, and divide by 8. 
You will notice that all these calculations are very simple, and are based on 
getting the number of cubic feet or cubic yards in stack, silo, barn, crib, or pit. If 
you know the weight of the cubic foot or yard, you can easily arrive at the rest. 
NUMBER OF SPLIT RAILS PER CHAIN (22 YARDS) REQUIRED 
FOR A TWO-RAIL FENCE. 
Length of Rail. No. of Rails. No. of Posts. 
9 ft. 6 in. 14 8 
Quzstion :—Supposing that you have a 3-rail stockyard, 10 panels long and 2 
panels wide, how many rails and posts would it take to make it double the size? 
Answer: 12 rails and 2 posts.
