Taking 300 as the probable number of days the vat would be used 
gives a daily depreciation of 25 cents. The number of days the vat 
was used each month and the quantity of milk handled during the 
same period afford a basis for determining the charge for deprecia- 
tion per 1,000 pounds of milk. 
The following figures were used in obtaining the charge for in- 
terest on investment:

The interest on $600 at 6 per cent amounts to $36 a vear, or $3 a 
month. Twenty-six runs a month, handling two batches of 2,500 
pounds each, gives 11.5 cents a day, or 2.3 cents as the interest charge 
for 1,000 pounds of milk.

The cost is figured on the basis of 1,000 pounds of milk because of 
_ the greater variation which would be shown when figuring on the basis 
of pounds of cottage cheese, owing to the variation in yield. Figur- 
ing on the basis of a yield of 18 pounds per 100 pounds of milk the 
cost per pound of cheese would be $0.0055, or a trifle more than one- 
half cent a pound, with no allowance for cost of package. These 
figures may be lowered with an increased volume of business; a de- 
creased volume would raise them. In fact, actual cost accounts main- 
tained at Grove City during a month in which 145,000 pounds of 
skim milk and buttermilk were made into cheese show that the cost 
of making cheese per 1,000 pounds of milk was only 85 cents. When 
only a small-quantity of cheese is made the regular creamery force 
may be able to do the work without any additional help, which would 
be an item of importance in determining the actual cost. 
MARKETS AND PRICES. 
In cities where large industrial concerns employ foreign labor 
there is already a good demand for cottage cheese, and a satisfactory 
market usually can be developed in other cities or localities. The 
market demands and prices fluctuate considerably with the condition
