Cost of Boiler-Room Labor,—This matter is of importance indeciding upon methods of handling coal in steam power plantsand some valuable information in this connection was containedin a report by Mr. R. S. Hale to the Steam Users Association,whose members represented nearly 400 mill owners, largely inNew England and the Middle States. Judging from the repliesreceived from members owning a total of about 600 boilers, itcosts to move coal by hand (wheel barrow) about cents perton per yard up to distances of five yards, then about cent perton per yard for each additional yard. Mr. Hale found that oneman, besides a night man, can run an engine and fire up to about STEAM POWER PLANTS. 151 1^^^^^. 152 STEAM POWER PLANTS. 10 tons of coal per week. One man, besides an engineer andnight man, can fire up to about 35 tons per week. Two men, be-sides an engineer and night man, can fire up to about 80 tons perweek. These figures assume that the night man does all he canof the banking, cleaning and starting. The figures are for aver-age conditions. If the conditions are exceptional, as, for in-stance, where there is a very long wheeling distance or a veryvariable load, proper allowance should be made. Mr. Hale statesin the report that mechanical stokers save from 30 to 40 per cent,of the labor in plants burning from 50 to 150 tons per week andsave no labor in small plants. Boiler attendants are paid about$ per day, working from 10 to 12 hours. The average costof firing coal, according to the report, was 48 cents per ton, themaximum 71 cents and the minimum 26 cents.
