352 ELEMENTS OF FARM PRACTICE 



Power in the Home. — Much of the work of the home, 

 too, may be done by machinery. Too many farms are well 

 equipped with machinery for outside work before much 

 thought is given to the work in the home. Home work on 

 the farm is quite as heavy and confining and important as 

 the work out-of-doors. Farm boys and girls should know 

 this and give as much thought to the use of power machin- 

 ery to lighten the work of the home as to the application of 

 power to the work of the farm. 

 Questions: 



1. Name all the different kinds of farm power you can think of. 



2. Which is Ihe most common kind of farm power in your com- 

 munity? For plowing? For pumping water? For grinding feed? 

 For hauling farm products to market? 



3. Tell all you can about the use of power machinery to lighten 

 the work of the home. 



Arithmetic: 



1. If a farmer keeps 50 head of live stock and each requires 8 

 gallons of water per day, how many gallons of water are needed to 

 supply these animals? 



2. If a boy can pump a gallon of water in 15 seconds, how long 

 will it take him to pump 400 gallons? If his time is worth 15c per 

 hour, what will be the value of the time spent in one year, if his time 

 is worth 25c per hour? 



THE USE OF POWER MACHINERY 



Know the Machine. — Most standard-make farm machin- 

 ery is reasonably well made and will give good se-rvice, if 

 well handled. Now that there is so much machinery used 

 in farming, a farmer needs to be a pretty good mechanic. 

 Young men seem to learn to handle machinery more easily 

 than older men. It is worth while for every farm boy to 

 learn the principles of operation of the more commonly used 

 machines. ' 



Care of the Machinery. — Some men use a tractor for 

 years and still always have it in working order. Some run 

 an automobile fifty thousand or a hundred thousand miles 

 and still get good service, while others have a very unsatis- 

 factory machine after using it a short time. The difference 

 is very largely in the care given the machine. A very im- 

 portant point in the care of a machine is to see that it is 

 oiled properly and kept oiled. A bearing may run for 

 months without any appreciable wear if kept properly oiled, 

 while an hour or so of running when dry will entirely ruin it.
