THE TRACTION-ENGINE 



gasoline engine when compared with the 

 steam engine is the quickness with which 

 it can be heated in the morning. In fact 

 you can start right off at once just as you 

 would do with an automobile. A 22 

 horse-power gasoline engine uses 35 gal- 

 lons of gasoline per day and 40 gallons 

 of water. This amount will last for ten 

 hours and plow about fifteen acres per 

 day on virgin land using 14 disc plows. 



Mr. William M. Jardine, United 

 States Agronomist, in charge of dry-land 

 cereals, discusses the merits of a typical 

 gasoline outfit working in Montana as 

 follows : 



"This outfit 22 horse-powerhad 

 been running for ten days and had 

 averaged during that time a little more 

 than 25 acres a day on heavy sod, plow- 

 ing to a depth of 4 inches and turning 

 it over in good shape. The cost, includ- 

 ing labor, was about 80 cents an acre.
