We give herewith data covering the cost of manufacturing ice and will guarantee that under reasonably fair management the number of men required will not be exceeded.
Do not fail to carefully analyze the following cost data. They may seem extremely low but a thorough study of our system will prove them to be very conservative.

NUMBER ONE
Manufacturing Costs Per Ton of Ice
Using Electric Power at Present Chicago
Rates for Power and Labor
Capacity of plant, 240 tons of ice per day, using 2692 cans of 400-lb. capacity.
18000-ton storage house.
Average current requirement for freezing one ton of ice, including storage cooling and all auxiliaries, 55 K. W. hours.
Average cost per K. W. hour, .9 cent.
Current cost per ton of ice, 55 x .9, equals 49.6 cents.
Assuming one month's shut-down for inspection and repairs, the total output of 240 tons of ice for 333 days amounts to 79,920 tons, or roughly speaking 80,000 tons of ice.
Adding 1/2 cent per ton of ice for the required heating, the total power
cost of making 80,000 tons of ice is (80,000 x .50) = $ 40,000.00
