The steamer gives you an hour in which to drift about in the sunshine and meditate upon the inferiority of any material other than water for the macadamizing of roads.
If the money now spent in macadamizing were spent in making the necessary bridges, the resources of the country would be much more fully opened out than they are at present; a garre-waller, or cart-man, can always appreciate a bridge, never a macadamized road. At present the bridges on this road are all wooden, and liable to be carried away by the first heavy flood.
It has nearly been accomplished already, by several different modes of construction; and there are very many streets where the luxury of wood pavement, which wears very rapidly, cannot be afforded, and where macadamizing will not stand the wear and tear of the heavy traffic.
Along its upper line, dig a trench five or six feet deep and six feet wide. Level the bottom of the trench, and make it impermeable by paving, by macadamizing, by bitumen, or, more simply and cheaply, by a layer of clay. By the side of this trench dig another, and throw the earth from it into the first, and so on until you have rendered the subsoil of the whole parcel impermeable to rain-water.
The road was filled in between the rails with cracked stones, such as are used for macadamizing streets. They keep the dust down, I suppose, for I could not think of any other use for them. By and by the glorious valley which stretches along through Chester and Lancaster Counties opened upon us.
