Consolidation. The road metal, gravel or broken stone, should be consolidated asquickly as possible. Loose material absorbs the rain as it falls, even beforeit is cut into ridges by wheels and the feet of horses. When it has been.

In this way the whole surface and foundation of the roadis softened, is readily cut up and destroyed. The best remedy for this waste in road-making is to spread the roadmetal to conform to the required surface of the finished road, and then thor-oughly consolidate it by the use of a heavy roller. It can be largely reme-died also by taking proper care of the road, if a roller cannot be had. Byraking the loose material into the ruts aiid wheel tracks as fast as they appear,or drawing if in with a grading machine, nearly the same end will be ac-complished; but less perfectly and requiring a longer time. The first vehiclepassing over the road does comparatively little injury; it is when ruts havebeen formed which hold water and other wheels follow in these tracks thatthe greatest damage is done.
