Unless, therefore, the freshes of the str be loaded with line sand, Avliich ( decompose the. turf, the em- bankment should always be under- taken at a considerable distance from the edge of a river. By placing die artificial bank at half the breadth of the stream, from its natural banks, its channel will thus be nearly doubled, and the detached space, in general, afford excellent pasturage. 2.
