Fheir presence — and it is a singular but well known principle in chemistry, that mere 'presence is apower called catalytic — induces it to absorb oxygen from the atmosphere, and to produce what is called humic acid. With this acid the alkalies immediately combine and tbrm salts, called humates, which are soluble in water, and atlbrd nourishment to plants. Thus when lime is properly applied to land, it brings into fruitful action the hitherto inert vegetable mould. But it must be obvious that i...f no additional vegetable matter is given to the soil, the effect of lime will be to exhaust it utterly, in a shorter time than might otherwise be done by cropping. Hence the saying, that liming land enriches the lather but impoverishes the son. It must not be forgotten, however, that the lime has enriched the father, by giving abundantly to his crops food that would otherwise have remained dead in his soil, or been eliminated by other agents, through a series of years, in feeble proportions, to scant, and therefore protitless crops : while, if it impoverishesMie son, it is because a wretched husbandry has taken all from the land, and given nothing in return.
