There was a credit, per year, of 0.93 of 1 calf for each cow. which 
amoimted to 0.03 of 1 calf for each 100 pounds of milk produced. 
Table 3. The credit for manure per cow per year amounted t o 7.749 
pounds, and for 100 pounds of milk it amounted to 264 pounds. 
Table 4.) It was estimated that a ton of this manure contained 9,o 
pounds of nitrogen. 2.9 pounds of phosphoric acid, and 9. S pounds 
of potash. Page S. 
In the winter season 54,3 per cent of the work was performed by the 
manager. 26.4 per cent by the hired men. 12.9 per cent by women, and 
6.4 per cent by boys and girls. During the summer 51.1 per cent was 
performed by the manager. 21.1 per cent by hired men. 16.S per cent 
by women, and 11 per cent by boys and girls. Table 6.) 
The building costs for the year were 13. S per cent of the capital 
invested in them, the equipment costs were 22.9 per cent of the capital 
invested in equipment, and herd charges were 10.4 per cent of the capi- 
tal invested in the herd. The combined cost of buildings, equipment, 
and herd was 12.6 per cent of the total capital invested in them. 
Table 8. 
Fifty-six per cent of the cost of milk was due to feed, bedding, and 
pasture, 16. S per cent to labor. 2.6 per cent to depreciation on cows, 
and 24.6 per cent to other costs. There was a credit of 6.2 per cent 
for calves and 7.4 per cent for manure. Table 9.) 
The average incomes from milk during the first winter and summer 
were not sufficient to meet the average costs during those seasons. 
In the second year the incomes were above the average costs in both 
seasons. Table 10.) 
The greater percentage of the year's income was received in the 
winter, but the feed, pasture, and bedding costs were heavier at this 
time and exceeded the summer costs by a greater percentage than the 
winter receipts exceeded the summer receipts. Table 11.)
