404 FARM AND SCHOOL PROBLEMS. 



value of buildings per acre? What was the average value of buildings 

 per farm? 



4. The value of implements and machinery on Ohio farms in 1910 

 was fifty-six million dollars. What was the value per farm if there were 

 271,000 farms in Ohio? 



5. Twenty-five million three hundred and fourteen thousand 

 dollars was spent for labor; $4,163,000 was spent for fertilizers. What 

 was the expenditure per acre if there are 19,210,000 acres of improved 

 lands in the state? 



1. A farmer lost $125 on a horse that became blemished by a loose 

 barbed wire lying on the ground. If it would have taken ten minutes 

 to have replaced the wire on the fence and nail it fast, what would his 

 time have been worth per minute, if he had repaired the fence when he 

 first saw its condition and had prevented the loss? 



2. If a set of buildings poorly arranged cause the loss of one 

 hour daily in doing chores, what is the total loss of time in one year? 

 What is the loss financially if the farmer's time is worth $2.25 per day? 



3. If a farmer loses $75 per year because of poor buildings and 

 lack of shelter for his farm animals, and this amount could be saved by 

 building a barn at a cost of $1,000, estimating money to be worth 6 per 

 cent., what would this farmer save in ten years by building a barn? 



4. If there is an investment of $500 in farm machinery, and there 

 is an average loss of 10 per cent, annually when it is not sheltered, how 

 long will it take for the loss to be equivalent to the cost of a $225 tool 

 shed? 



5. Which is the cheaper, a farm of 80 acres that has a set of new 

 buildings erected at a cost of $3,000; the fields fenced with 760 rods of 

 fence at a cost of 60c a rod; ditched at a cost of $20 an acre; if it can 

 be purchased with these improvements at $200 per acre or to purchase a 

 farm of the same size with identically the same kind of soil but without 

 buildings or fences or ditches at $150 per acre?
