An Ideal Industrial Locomotive: 

 No Smoke, No Steam, No Coal 



WITH coal scarce and gasoline high- 

 priced and much in demand for all 

 of our war activities, the oil-lired steam 

 locomotive, burning heavy grades of 

 distillate or crude oil, is now winning 

 favor in plants where switching engines 

 haul goods over short distances. The oil- 

 fired locomotive has many uses. It is 

 found hauling logs 

 in camps far away 

 from coal supplies; 

 or wending its way 

 on sugar planta- 

 tions ; or busily 

 transporting from 

 the excavations for 

 New York's new 

 subway system 

 muck, rails, ties 

 and ballast. Con- 

 tractors select the 



oil-fired locomotive because it does not 

 pollute the atmosphere with smoke. 



In appearance, the fuel-fired locomo- 

 tive, as shown in the accompany- 

 ing illustrations, does not differ much 

 from the familiar coal-fed type, except 

 that a separate tank out in front of the 

 boiler takes the place of the usual coal- 

 tender. The cost of operation is said 

 to be less than one cent a ton per mile. 

 The construction is clearly shown in the 

 accompanying cross-sectional view. 



Note the oil-tank in front of the boiler, 

 which replaces the cumbersome coal-tender 



Death Traps in Seemingly Unoc- 

 cupied Fields at the Front 



THE precautions taken by the officers 

 of the allied forces in order to pre- 

 vent their men from falling into German 

 traps during the excitement of an at- 

 tack are brought out in a statement made 

 by Major-General Charles M. Clement, 

 of the United States Army, who visited 

 the firing line in France. 



"When I studied 

 army tactics some 

 years ago," he said, 

 "we had five points, 

 represented by the 

 five fingers of our 

 hand, and there 

 was nothing said 

 about killing any- 

 body. But an ar- 

 my order today 

 reads: 'The object 

 of this attack is 

 (a) to kill the Germans; (b) to reach hill 

 number so-and-so; (c) to stop at hill 

 number so-and-so'; and woe betide the 

 man who goes beyond the stopping 

 point!" 



These explicit instructions were given. 

 General Clement explained, because the 

 enthusiasm of the French and British 

 soldier frequently- urged him beyond the 

 objective; and fields back of that, which 

 appeared to be unoccupied, often proved 

 to be cleverly camouflaged death traps.
