As motor traffic increases, a point is reachedwhere the type of road has to be changed, and thispoint varies with the volume of horse traffic and thevolume and speed of motor traffic—a condition in partbrought about by a failure of the motor vehicle to pro-duce sufficient wear on the road surface. It is those who have the building- and maintenanceof our rural liigliways wlio are most seriously effected. Chert Road, Florence, Ala. United States Object Lesson Road.

It is comparatively easy tocontrol the speed of motor traffic, through our largertowns and over the park systems of our cities and itis admitted that at low rates of speed the motor ve-hicle is no more injurious to the road than ordinarytraflic. But, is the open country, where we have thegrinding action of the iron tire and heavy load fol-lowed by the high-speed automobile throwing up anddistributing the products of wear, we are confrontedwith the necessity of providing a new and more dura-ble form of road. For several years past, highway engineers and have been uniting their efforts in attempts t;_) .solvethis problem, and, generally speaking, have experi-mented along two lines, either to add some palliativeto the surface of the road in order to hol
