Présentation de l'éditeur

The Origin and Character of Soils Soils A re Rock Waste. Soils were not originally a part of the earths surface, but have been formed slowly by the crumbling and breaking up of the surface rocks into fine particles, such as clay and sand. Sometimes this breaking up occurred where the soils are now found, and the character of the soil is governed by the kind of rock that was left on the surface, while in other cases the rocks and the soil that came from them have been carried thousands of miles and mixed with other material, forming a conglomerate mixture from many sources. The highland and mountain soils in this country have, as a rule, been formed very near the places where they are now found, while the soils in the larger valleys, and along most of the coast line, have resulted from material washed down from the hills and deposited along the level stretches near the sea. Much of the soil of the more northern states has been brought down from Canada by the movement of ice along the surface. This breaking down of the rocks and formation and moving of the soil has taken a long time; but this work is yet going on, and the exposed rocks, boulders and ledges in our fields and mountains are yearly being attacked by the different forces, and are slowly yielding up material to help replenish the older soil. Different natural and artificial processes are also going on in the soils that may either improve or injure them. Most of these processes can be controlled by man and made to be his servant, so that he can become a great factor in the formation of profitable soil.
