108 DAIRY FARMING 



work of cutting ensilage and corn stover, as well as run- 

 ning a saw and grist mill. 



This is an age of machinery, and we believe the time 

 is not far distant when the farmer will make use of 

 power whenever this can be made to take the place of 

 hired labor. Power will not only afford greater con- 

 venience but will curtail the running expenses of the 

 farm. 



If, for example, we assume that one hour is required 

 daily in running the separator, and another in pump-- 

 ing water for stock, the total time consumed in 

 this work in one year would be 730 hours, or 73 days of 

 10 hours each. At $i a day, the cost of separating and 

 pumping would amount to $73 a year. With a gasoline 

 engine running the pump and separator at the same 

 time, this work could be done in 365 hours. Allowing 

 6c per hour for gasoline and oil, which is a high esti- 

 mate, the cost of doing the above work with an engine 

 would be $21.90, or less than one-third of what it can 

 be done for with hired labor. This saving is equivalent 

 to about 25 per cent on the investment of the engine, if 

 used for no other purpose than separating milk and 

 pumping water. 



At silo filling time the engine should be mounted on 

 a suitable base near the silo, where it is expected to re- 

 main only during the rilling of the silo. The remainder 

 of the year it may be placed as indicated in the above 

 illustration. 



There are plenty of simple and smooth-running gaso- 

 line engines upon the market, and in purchasing care 

 should be taken to get one in which these two qualities 

 are most conspicuous. 



A possible objection to the use of gasoline engines for
