294 The Silo and Silage-stack Competition, 1885-86. 
and cost 9?. The floor is paved with brick and cement. There are no drains, 
and it is roofed with Welsh slates; but a well was sunk in the corner, about 
1 foot 6 inches by 3 feet, and 1 foot deep; this was full of liquor, none 
having escaped. There were 33 acres of grass cut and put into the silo from 
the adjoining fields, as the back of the silo was on a level with the field. 
The carts were drawn up and their contents easily thrown into the silo. Mr. 
Collingwood gave us a very carefully compiled statement of the time and 
quantity of grass put in —

It therefore appears that the silo took just 8 weeks to fill, and Mr. Colling- 
wood returns the expenses as follows : — 
£ s. d. 
33 acres mowing;, at 4s 6 12 0 
403 loads, at Is. 6c? 30 4 6 
5 men at 3s., 10 days 7 10 0 
£44 6 6 
This seems very expensive, as it amounts to 30s. per acre ; it was estimated 
that about 400 tons of silage was made. The plan of weighting was by 
two screwjacks on beams, which were attached to the bottom of the silo. No 
earth, bricks, or sand were used for weighting. The subsidence altogether after 
pressure was about 2 feet. If the silo had been filled to the top there would 
have been 500 tons in it. The quality of the silage was good, a very little 
damaged, and the plan for utilising the fodder by removing it at once from 
the silo into the cliafl'-house for the cattle was excellent. A largo number of 
milking cows arc kept for use of the college, which has upwards of 300 students, 
and the President, Professor, and educational staff, with attendants, com- 
prising a large number, so that the consumption of the inmates was very 
great. The sheep were fed last season on the silage, and they ate it 
voraciously, and did exceeilingly well. Mr. Collingwood considers lie 
keeps at least one-third more head of stock on the same acreage by silage 
than on hay.
