or nearly 460 cubic yards. The hay in such a stack would weigh perhaps 150 lb. 
per cubic yard (but this is a very variable quantity) ; hence the total weight of 
hay would be about 244 to 25 tons. If it is a wheat stack, we may take a cubic 
yard to represent one 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 CALCULATE THE WEIGHT OF HAY IN THE STACK. 
Hay necessarily varies in weight, according to quality, size of stack, 
age, &c. 
New hay may weigh 8 or 10 stones per cubic yard (112 or 1401b.). 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 lb. as the weight of a cubie yard, such a stack as we 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 
(Baildon); but, if the crop has been mown, a yard will not average more than 
3 pecks. 
ce STACKS OF STRAW 
may be estimated at the rate of 18 to 20 yards to a ton. 
CONTENT OF SILOS. 
A QUESTION was put to us the other day which involves more intricate 
calculation. A farmer has a quantity of sorghum which he wishes to put into 
a silo, and wishes to know what sized building he would require. We find 
that his crop will take up a volume of 25,000 cubic feet. 
We know that a building 20 feet long, 12 feet broad, 10 feet high to the eaves, 
with an additional height of 6 feet from eaves to ridge will contain 2,880 cubic 
feet. Now, without going into the calculation here, which involves the 
extraction of the cube root, we find that, by doubling all the dimensions above 
given, the building will hold 24,960 cubic feet of silage. 
Bush Work. 
By A. J. BOYD. 
Wirn the advent of fencing-wire and wire-netting, the occupation of the 
splitter and fencer is no longer of the importance it possessed in the early 
days. Galvanised ironalso has almost done away with the shingle-splitter, and 
wire-netting takes the place of palings. Still, whilst timber remains, and scrub 
farms are yet the home of the tecund wallaby, the farmer, not overburdened 
with cash, finds that a knowledge of splitting comes in very handy, and saves 
him from much immediate outlay. He requires slabs for his first dwelling, and 
shingles to roof it with, unless he can obtain a good supply of stringy or box 
bark. Palings are an absolute necessity on farms cut out of the heart of our 
dense scrubs to keep out the destructive marsupials. Where good splitting 
timber is available, it is foolish waste to burn it off and then pay down solid 
cash for wire-netting and galvanised iron. Stockyards and pigyards also will 
use up a large quantity of post and rails, all of which have to be got out of the 
timber covering the farm.
