When the road must be constructed out of the mate-rial over which it passes, it is often possible to select aroute where the soil is better adapted for the purposethan that found where first located. Upon one sideof a valley the surface may be clay, upon the oppositeside gravel, and in the bottom of the valley the soilis usually alluvial—higher up the ground is generallyfar more fit for raad purposes. In starting the construction of any road tlie wiilthand shape of the cross section has necessarily to bedetermuied. The practice is too common of design-ing a uniform cross section for a roa .i regardless ofthe character of the soil and the drainage area tluit theditches must serve. A uniform cross secticm for allparts of the road should not lie adopted.
