FOR BETTKU ('HOI'S 115 



when the crank is about 10 degrees below center, while some 

 extremel}' high speed engines should ignite about 70 degrees 

 below or before dead center. This latter applies more especially 

 to automobile engines. 



The farmer who knows the principle of the action of the 

 gases in his engine and understands his ignitor, will have no 

 trouliles other than those which come up l:)ecause of wear and 

 poor adjustment or lack of care, and these troubles he must 

 learn to adjust as the}' come about. 



A Comparison — Men who are driven will sulk, will complain, 

 and linally|strike, but few will ever overwork. A horse will work 

 on, no matter how much he is required to do and no matter how 

 badly he is crippled up. A steam engine is like a horse — i-t can 

 be overworked to its detriment — and if it gets out of order it 

 will run on just the same until it is practically ruined. A gas- 

 oline engine is like a man — if it is overtaxed it quits, and if it

is out of order it will not run. It is like a man in another 

 respect. It is always ready to start, does not have to be driven 

 in from the pasture; neither does an hour's time need to be 

 wasted to get its motive power in the proper condition to use. 

 Furthermore, it is not dangerous when handled either by ex- 

 perts or novices. It will not run away, it will not kick, nor will 

 It explode its boiler. 



Men have been known to say that horse labor is cheap, and 

 some men believe it is. But can they prove it? Transfer com- 

 panies in the prairie states make the claim that it costs $125 per 

 year to feed a horse. Of course these horses are all work horses, 

 and most of the time they work. The Minnesota experiment 

 station has proven that it costs approximately $80 to maintain 

 a farm horse for a year, and the horse only returns about three 

 hours' work per day for this, which makes the cost of his services 

 to the farmer amount to about eight cents per hour. In addition 

 to this must be counted the depreciation, interest, and taxes.
