To quickly assess the difficulty of the text, read a short excerpt:
Penfold says that the ruts formed by wheels ought not to be filled up with loosje broken stone, thus forming a ridge of materials possessing greater hardness than the parts imme- diately adjacent thereto, bu that the rake should be worked back and forth across the rut and on either side of it, the object being to unite the old loose material with the new, in some degree at least, so that the patch will be as little unlike the unrepaired portions as possible. By this method of mending, a cubic y...ard of stone will usually suffice for a superficial rod of depressions and incipient ruts. The cov- ering of large areas, exceeding eight to ten square yards, should not be undertaken at one time, and Avhere there are several depressions in close proximity to each other, the worst should be patched first, and allowed to get even and solid, before the others are taken in hand. " It is one of the greatest mistakes in road making that can be committed, to lay on thick coats of materials, and when understood, will no longer be resorted to.
