The dairy constructed by Mr. Falconer was built on this principle, with a 
brick chimney. Butter was kept in it for months in sound condition, and the 
interior was so cold that no one would care to remain in it for half-an-hour. 
We have, unfortunately, not got the model of Mr. Falconer’s safe, but Mr. 
Monks has suggested the accompanying construction.

TO FIND THE CONTENT OF A STACK. 
Consider an oblong stack 40 feet long, 12 feet wide, 8 feet high as far as the 
eaves, and 6 feet from the eaves to the crown. Take the lower portion first. 
Multiply the length, breadth, and height together (the height to be measured 
from the ground to half-way between the eaves and the crown. Thus, 
40 x12 x 8+4 of 6) that is 40 x 12 x11 = 5,280 cubic feet = 1955 cubic yards. 
Any oblong stack can be calculated roughly in this way. Suppose, however, 
the stack to be built so as to bulge at the eaves. In this case the body of the 
stack must must be calculated separately. Instead of 12 feet, it is, say, 14 feet 
wide at the eaves, so the seen nest will be 18 feet, and the height to the 
eaves 9 feet, while the end of the crown from the eaves is 8 feet. 
Now, 40 x 13 x 9 = 4,680 cubic feet in the body of the stack, and the content 
of the roof will be 40x14x4 = 2,240 cubic feet. Add these two quantities 
together ; we have, 4,680+2,240 = 6,920 = 256% cubic yards. The surest way 
of getting at the weight is to weigh 1 cubic yard. 
In old haystacks, 8 cubic yards will weigh 1 ton. For new hay well 
settled, about 10 yards will represent 1 ton. 
Of wheat, 1 bushel of grain may be reckoned to the solid yard. oN
