الصفحة 328 - Bodens, undertakes to be a courier. Indeed, Tom, you have betrayed yourself too soon !

An atmosphere of carbonic acid, formed at the expense of the oxygen of the air, surrounds every particle of decaying humus. The cultivation of land, by tilling and loosening the soil, causes a free and unobstructed access of air. An atmosphere of carbonic acid is therefore contained in every fertile soil, and is the first and most important food for...
