The soil originally consisted simply of the debris of the rocks or clay. It is composed of the elements of the rocks, together with an intimate admixture of some mim ral sub- stances. In limited patches the soil partakes of the charac- ter of the formations underneath. Thus, in iron districts, the soil in places shows the presence, in considerable quan- tities, of iron, making the earth red or brown. In sand- stone countries the clay has a* quantity of sand overlying it, and among the primitive... rocks scales of mica glisten on every side. The weight of a cubic foot of thoroughly dried soil averages as follows: (113) Pounda. Siliceous sand 111. 3 Calcareous sand, 113. 6 Sandy clay 97. 8 Loamy clay, 88. 8 Stiff clay 80. 3 Slaty marl 112. Fertile mould 68. 7 Common arable soil 84. 5 Chemists, from the earliest times, have been struck with the great proportion of insoluble to soluble substances in the soil. These insoluble substances will resist the action of acid and alkali in any quantities short of destroying vegetation.
