Still other precautions are for the pur-pose of eliminating or reducing coal losseswhich occur more or less independentlyof the efficiency of the combustion pro-cess. Coal when placed on tenders shouldhe trimmed so that there shall be no lossthrough falling off on the road bed. Coalshould not be allowed to fall or blow awayfrom the engine deck. The sprinkler hoseshould be used enough to keep down dustand to prevent fine coal from blowingabout. Unnecessary stops for coal or water orother unnecessary stops which may bewithin the control of the engine crewshould not be made. Each stop and startrequires the burning of additional of delays of this kind in so faras they may come wit
