As loose material 9 inches in depth were used, the cost per 

 square yard was therefore about 25 cents. The total amount of 

 material used in the road was 672 cubic yards, and the total cost 

 was $780.00. It will be noticed that 672 cubic yards at $1.00 

 per cubic yard would amount to $672.00, leaving a little more than 

 $100 for culvert pipe and construction of culverts, repairs to tools 

 and machinery and for incidentals. The cost of this work was 

 probably 15 per cent, lower than would be the case in ordinary 

 practice, as the machinery, expert operators and superintendence 

 were furnished free by the Government. 



It will be noticed that no charge was made for piling material 

 at the crusher. This was on account of the fact that the material 

 was furnished free already piled; for, in order to cultivate their 

 crops, the farmers had found it necessary thus to dispose of the 

 rock found in the fields. This fact, however, could not have 

 materially affected the cost of the road, as similar material could 

 have been secured nearer the work, but as it would have been 

 necessary to pick up the rock from the fields, the cost of picking, 

 piling and hauling would have amounted to about the same. 



Taking the culverts and incidentals into consideration, this road 

 cost about 35 cents per square yard, or at the rate of $3,285 per 

 mile for a 16-foot road, which is considered a very reasonable cost 

 for first-class work. It would be safe to say, therefore, that roads 

 built under practically the same conditions even after adding the 

 necessary cost of expert supervision, interest and depreciation on 

 plant, can be constructed for about 38 to 40 cents per square yard, 

 or at the rate of $3,750 per mile for 16-foot roadway. 



The cost of the road at Springfield, Mo., should not be accepted 

 as a standard for the whole country, for the following reasons: 

 First: Ordinarily there would be a charge for quarrying stone of 

 from 15 to 25 cents per cubic yard; the average for the whole 

 country would probably be 20 cents per cubic yard. This item 

 alone would increase the cost given above 5 cents per square yard. 

 Second: The cost of rough grading, which varies between wide
