The General Government, having withdrawn from the field of road construction in 1832, has since done little in that line until very recently. Eight years ago Congress appropriated a small sum of money for the purpose of instituting a sort of inquiry into the prevailing condition of things pertaining to road matters. This appropriation has been continued from year to year and increased during the last two years with a view of coöperating to a limited extent with other efforts in road construction.
The General Government can perform certain duties pertaining to scientific road improvement better than any other agency. Scientific facts ascertained at one time by the General Government will serve for the enlightenment of the people of all the states, and with no more cost than would be required for each single state to make the investigation and ascertain the facts for itself.
With a view to securing scientific facts in reference to the value of road-building materials, the Secretary of Agriculture has established at Washington, D. C., a mechanical and chemical laboratory for testing such material from all parts of the country. Professor L. W. Page, late of Harvard University, is in charge of this laboratory, and has tested many samples of rock without charge to those having the test made. There is, however, no test equal to the actual application of the material to the road itself.
With a view to making more extensive tests than could be done by laboratory work alone, the Director of the Office of Public Road Inquiries has, during the past two years, coöperated with the local authorities in many different states in building short sections of object-lesson roads. In this work it is intended not only to contribute something by way of coöperation on the part of the General Government, but also to secure coöperation on the part of as many different interests connected with the road question as possible. The local community having the road built is most largely interested, and is expected to furnish the common labor and domestic material. The railroad companies generally coöperate, because they are interested in having better roads to and from their railroad stations. They therefore contribute by transporting free or at very low rates the machinery and such foreign material as is needed in the construction of the road. The manufacturers of earth-handling and road-building machinery coöperate by furnishing all needed machinery for the most economical construction of the road, and in many cases prison labor is used in preparing material which finally goes into the completed roadbed. The contribution which the General Government makes in this scheme of coöperation is both actually and relatively small, but it is by means of this limited coöperation that it has been possible to produce a large number of object-lesson roads in different states. These have proved very beneficial, not only in showing the scientific side of the question, but the economical side as well.
