3382 HEARINGS BEFORE COMMITTEE ON AGRICULTURE. 
power, in the way of animals and teams, to do the work, we will send 
the rock-crushing machinery, the rock crusher and rollers, and earth- 
handling machinery, and skilled persons to operate that machinery 
and show them how to build a section. Sometimes we make as much 
as half a mile, and generally try to make about a mile. In one or two 
instances I have gone so far as to construct 2 miles inthis way. That 
is, I pay no money, but I send a man to superintend the work and 
another one to operate the machinery. That is the extent of the 
The Cuarrman. As to this machinery, I see further on in ‘‘new 
legislation” you want to buy machinery. You say, ‘‘for necessary 
office fixtures and supplies, apparatus, machinery, and materials.” 
The Department has built object roads, then? 
Mr. Dopee. In this way; we have never built a road by purchasing 
the material and building the road apart from cooperation. We 
simply give the service of our men to direct this work, and we secure 
machinery. We have been able to do that heretofore by manufacturers, 
who, in order to have the indorsement of the Government officials, in 
so far as that is given by the use of machinery, have been willing to 
furnish it to us. Iam inclined to think that they will continue todo 
so, but am not absolutely sure. It is this way, if they have an abun- 
dance of machinery in stock, they are willing to oblige us, but if they 
have demand for it, of course they do not like to oblige us. Some- 
times we have not been able to get everything we wanted. 
The CHarrman. Road machinery consists of the modern scraper, the 
stone crusher and roller, does it not? That-is about what machinery 
you use? , 
Mr. Doper. We have an automatic spreading cart, so when the 
crusher has finished the crushing of a rock and leaves it in a bin, and 
that goes by gravity into the cart, and is spread without the use of 
manual labor. 
The Cuarrman. It is something on the manure-spreading type?! 
Mr. Dover. Well, possibly; it does not require relifting or reshelv- 
ing. It isa great saving by showing how this can be done from the 
field and finished without the expenditure of a great amount of labor. 
We are able to show people how they can produce roads for about 
$3,000 a mile, which I think are fully as Bod: as many they have built 
at $6,000 a mile. Now, in my county, Cuyahoga County, Ohio, they 
have been building roads for the last ten years that cost from $12,000 
to $20,000 a mile. I was requested to give something in the way of 
information and instruction in object lessons, which T have done; and 
we have produced roads in parts of that county, and one in the adjoin- 
ing county, and it seems the roads that we have built at $3,000 a mile 
are as good as those at $12,000 a mile. 
Mr. Henry. How wide is the road? 
Mr. Dover. Twelve feet wide. 
Mr. Henry. How deep is the stone? 
Mr. Dopexr. Eight inches. 
Mr. Henry. Is that enough? 
Mr. Doper. We think it is. 
Mr. Henry. Does your machinery handle the coarser stone or only 
the finished 
Mr. Doper. It handles the crushed stone. Sometimes we put down 
a base of uncrushed stone. We do not recommend that. If we have
