The weight of silage is slightly less than that of the green fodder it is 
made of. 
Mr. Walter Madden (Victoria) says :—‘ The same 50 acres of green stuff 
that would produce 100 tons of hay at a cost of about £1 per ton for making, 
would produce 300 tons of silage at 2s. per ton for the making. The 300 tons 
of silage when made would be worth at least double the amount per ton that 
the hay would be worth.” 
Ten tons of green fodder equal 3 tons of hay, and 10 tons of green 
fodder will make almost 10 tons of silage. 
The hay would feed a beast for 120 days, and the silage for 400 days, and, 
in addition, the silage-fed beast will milk better than the hay-fed one. 
The milk produced by silage is richer in cream, the butter is sweeter and 
of a better colour, and the cost of feeding is about one-half as compared with 
bran and chaff. 
Maize and barley make the best silage. 
Green fodder should be put through a silage-cutter. This saves heavy 
weighting. 2 : 
The silo should be filled at intervals, allowing the first layer of 8 or 4 feet 
to heat up to 125 degrees before adding more. 
The silage should be well tramped down and packed tight in the corners. 
Silage should be fed from the top. 
Stack silage need not be weighted. 
Silage should undergo thorough fermentation to turn out good. 
A. stack of 50 tons will take about six weeks to reach 2 maximum tempera- 
- ture of 160 degrees Fahr. It will then gradually go down until in about four 
months the normal temperature is reached. 
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. As each 50 cubie feet of silage weighs a ton, this gives 57 tons 
12 cwt. as the capacity of the silo, 
TO KIND THE CONTENT OF A ROUND STACK. 
Wiens very great accuracy is not required, the content is sometimes found by 
taking the height of the stack from the ground to the eaves, and adding to 
this the third of the height from the eaves to the crown—the sum of these by the 
mean girth gives the cubic content. 
The content thus found is less than the truth, but the loss is not great, 
seeing that the stack is not so dense at the top as at the bottom. 
TO FIND THE MEAN GIRTH WHEN THE STACK TAPERS 
; REGULARLY TO THE EAVES. 
Add together the girth taken at the bottom of the stack and the girth 
taken at the eaves, both in feet; then half the sum is the mean girth. When 
the stack does not taper regularly, girths must be taken in several places and 
added together, and their sum divided by the number of girths taken; the 
quotient is the mean girth. Then with the mean girth found in one of these 
ways and the height of the stack from the ground to the eaves, find the content 
of this portion of the stack. 
Next find the content of the top portion or roof by taking the girth at the 
eaves multiplied by the perpendicular height from the eaves to the crown of 
the stack, the third part of which is to be added to the content of the body 
portion already found, and their sum shows the content of the stack in solid 
yards and feet.
