What reading level is The Principles And Practice of Land Drainage book?
To quickly assess the difficulty of the text, read a short excerpt:
There is sometimes found at the depth of a foot, or it may be of two or three feet below the surface, a layer of impervious clay, through Avhich no water can pass, but on the top of which it must flow, if there be an inclination in any direction, with the effect of keep- ing the surface constantly damp and cold. In all parts of the state such lands may be found ; they appear mel- low and rich, but are always cold and weedy, and produce no valuable crop. They are much more easily and cheaply und...erdrained than clayey lands, because a differ- ent system may be pursued; and when drained, they soon lose all their disagreeable and unproductive qualities.
5. Clayey and Impervious Soils. — Clayey soils trans- mit water downward, but slowly; and consequently, in a wet time, the surface soon becomes perfectly saturated with moisture. It is too wet for crops, too wet to till, too wet to bear the tread of animals ; in short, it is too wet for anything. In drying, it sets hard, and becomes more unmanageable than ever ; the roots of grasses or other plants can not penetrate to any considerable depth, and clayey lands are therefore the first to suffer from ex- cessive drought, as well as from excessive moisture ; there is scarcely a season that exactly suits them, and only a limited portion of the best of seasons that they can be comfortably worked.
