A YEAR'S WORK IN AN OUT-APIARY 61 



Set the spark-lever at slow, or at the place you put it for slow running 

 when on the road. Do you wish a 3,000-a-mlnute gait for your buzz- 

 saw or planer? Set the spark-lever at a 25-mile-an-hour gait and you 

 are at home in the matter. 



The main thing in running machinery with the auto is to know 

 how to time the matter of oiling the latter. The instruction-book which 

 comes with the auto will tell us how many miles it is to be run to 

 once oiling of certain parts. But the auto is not making "miles" now, 

 but revolutions. By getting the number of inches the revolving wheel 

 is in circumference, and dividing the number of inches there are in a 

 mile by it, we can ascertain the number of revolutions the wheel would 

 make in going a mile on the road. Then by multiplying this by the 

 number of miles we were allowed to run for once oiling, we shall have 

 the number of revolutions the jacked-up wheel can make without danger 

 from lack of oil. Now with a speeder find the number of revolutions 

 the drive-wheel is making per minute when the spark-lever is set for 

 different degrees of speed, when it is easily told how many minutes or 

 hours can be safely run on one charge of oil or grease. Where any 

 apiarist lives in a location where the auto can be run the most of or 

 all of the year, he can well afford to let his horse and wagons go, and 

 purchase an auto; but If in a locality like mine, then it is best to ask, 

 "Can I and my family afford both," before buying one?
