The average acreage yield in pounds or the acreage coefficient 

 varies with the locality. As market roads are usually located 

 through farming country, the weight of crops per acre of farm land 

 is a good indication of the tonnage originating on market roads. 1 

 The report of the 1910 Census shows an approximate average 

 product of 332 pounds per acre of farm land. The average yield 

 per acre on improved farm land in crops was 1,674 pounds. 2 The 

 average weight per acre of forest products on unimproved farm land 

 was 122 pounds. 3 



It is found that usually 20 per cent of the roads in any county 

 carry nearly all the traffic — possibly 90 per cent of the total. In the 

 United States 20 per cent of the total mileage of roads is about 

 440,000 miles. There is an average of about 2,000 acres of farm land 

 to each mile of such road, which should represent about 65 per cent 4 



i There is a considerable return haul of fertilizer, fuel, kerosene, supplies, wire fence, etc., which can be 

 partially determined by thorough inquiry of dealers. 



2 A careful computation of the weight per acre of all marketed crops in Tompkins County, N. Y , based 

 on the data of Bulletin No. 295 of the Cornell Agricultural Experiment Station, gave 0.51 ton per acre of 

 land in cultivation, which was 70 per cent of the total farm area and 63 per cent of the total area. The acre 

 yield for the entire area was, therefore, 0.35 ton. 



s These figures are derived by determining the weight and acreage of each crop reported and by making 

 reasonable assumptions as to distribution in the case of fruits, etc., where acreage was not given. (See 

 Table 2.) 



* The average per cent of lands in farms in 39 States which reported more than 20 per cent of their areas 

 in farms in 1910 was 65.16.
