Sand is often cemented with lime, organic matter, iron, etc., into hardpan, whichis often troublesome, but ordinarily it is loose and porous to a great depth. Theproductive ability of a sand soil is very largely dependent upon the size of its granules,upon which in turn depends its ability to imbibe plant-food and moisture. Sandalmost always looks sterile and forbidding; but it is unsafe to judge a soil for forestalpurposes from the appearance of its surface. A sand soil may look, in fact may beabsolutely sterile on the surface, and yet a few inches below be rich in appearance of the surface of such a soil would condemn it of course for agricul-tural but not for forestal purposes, because the roots of trees would soon penetrate.
