506 FARM AND SCHOOL PROBLEMS. 



one ton per load and make two trips per day; if he values the time 

 for driver and team at $3.50 per day, how much does it cost this farmer 

 per ton per mile to deliver his products to market? 



2. If the same road described in problem 1 were ditched, drained, 

 graded, and macadamized, what would be the cost per ton per mile to 

 haul two tons per load twice a day at $3.50 per day? 



3. What is the difference in cost per ton per mile, between hauling 

 over the bad and hauling over the good roads described in the two fore- 

 going problems? 



4. If a farmer can haul two tons per load, twice a day, a distance 

 of 5 miles over a macadamized road, which is twice as much as he can 

 haul over a poor road, how much does the good road save him per 100 

 tons per mile? 



5. If the average cost of Macadamized roads in the United States 

 is about $5,000 per mile, how many years will it require to save enough 

 to the farmer as shown in problem 4, to more than equal the cost of the 

 road per mile? 



6. There were 125,000 automobile licenses granted in Ohio in 1914, 

 at $5.00 per license; what was the amount of this license in Ohio? How 

 many miles of roads could be improved at this rate annually at $5,000 

 per mile? 



The total loss suffered by the farmers of the U. S. on ac- 

 count of bad roads is not alone in the extra cost of hauling. 

 There are many other items that may be added such as bad 

 markets, shrinkage, damage to horses, and various other losses. 



PROBLEMS. 



1. If investigations made by the U. S. Dept. of Agriculture show 

 that the general average cost of hauling 23 different farm products to 

 market is 5.22 per cent of their value, what would be the cost of market- 

 ing one-half of the total farm crop of 1914 if it is approximately valued 

 at 10 billion dollars? 



2. If the average cost of marketing corn is 9.6 per cent of its value, 

 what would be the cost of hauling half of the corn yield of the U. S. 

 if the average annual production is about 2,500,000,000 bushels, basing 

 figures on the present market value? 



3. The average cost for hauling on all sorts of roads in the U. S. 

 is about 25 cents per ton mile; investigations in Europe show that the 

 average there on good roads (dry stone roads) is 8 cents per mile; how 

 many per cent greater is the cost on the average in the U. S. than on the 

 European road ?
