Not indexed. Not illustrated. 1866 Excerpt: . . . both track and machinery. Where the ballast sinks, many of the sleepers will be left clear and hanging by the rails. These, on the passage of a train, deflect deeply, thus opposing a heavy grade against the wheels. This is proved by the oozing of mud from under the ends of the sleepers in wet weather, and the dissipation of clouds of dust in dry seasons. Water, standing in contiguity to earthwork, is equally injurious. No matter what may be the height of an embankment of loam, sand, or clay, water, if in reach of it, will rise to the top, being carried by absorption, and will produce all the effects just stated. Water not only destroys the cohesion of the material of the road-bed, but swells its bulk. It is sure to displace the best laid track. In cuttings, water will thus convert the whole road-bed into mud. Whenever this dries in the sun it is partly dissipated in dust, while clayey soils will shrink and crack in every direction. The slopes, already worn into gullies by the action of running water, will also fill with dust. On the other hand, frost setting in just after a heavy rain, or while the road-bed is otherwise soaked from stand ing water, will heave the track irregularly and hold it there, as rigid as rock. No condition can be worse. When, in the following spring, the frost is coming out of the ground, and the road-bed is washed by the thaws from adjacent lands, the earthwork reaches its complete stage of saturation. Stratified soils will thus slip, if ever. In an economical view, the damage occasioned by water is far greater than the utmost cost of its removal. It does not need extreme conditions to produce the effects stated. Partial saturation, occasional washing of banks and moderate rigidity in winter, are all sufficient to disturb the track. . .
