Total Tons 18750

During the month of December, the Ice Plant will be shut down for
overhauling and repairs, and part of the ice stored during November
will be sold in December, therefore, requiring a total storage
capacity of 18,750 tons, of which 750 tons will be stored in the
ante-room and 18,000 tons will be stored in the big winter storage.

NOTE--These sales can only be realized if the dealer has at least
18,000 tons of natural ice on hand to enable him to take care of the
family trade during the hot months.

If no large supply of natural ice is on hand hardly 50,000 tons can be
sold, thereby increasing the cost per ton considerably.

POWER COST:

Due to numerous starting and stopping of compressor during the slack
months the maximeter charges will be higher and therefore it must be
assumed that 60 K. W. hours will be required per ton of ice instead of
55 K. W. hours for continuous consumption.

60 K. W. hours per ton of ice at .9 cent per K. W. hour equals 54
cents per ton. Adding 1/2 cent per ton for the required heating the
power cost for making 60,450 tons of ice equals 60,450 x 54.5 cents,
equals $ 32,945.25

ENGINE ROOM LABOR COST:

1 chief engineer per day $ 10.00

3 engineers per day $ 8.00

Total per day $ 34.00

365 days at $34.00 equals $ 12,410.00

or 12410 / 60450 = 20.54 cent per ton of ice

ICE PLANT LABOR COST:

(Using present method of pulling ice)

May, June, July, August, September and October require:

6 ice pullers per day $ 6.00

3 air men per day $ 6.00

6 storage house men per day $ 6.00

Total per day $ 90.00

184 days at $90.00 equals
