Book Synopsis The Formation of Vegetable Mould Through the Action of Worms (Annotated) by : Charles Darwin
Book excerpt: The share which worms have taken in the formation of the layer of vegetable mould, which covers the whole surface of the land in every moderately humid country, is the subject of the present volume. This mould is generally of a blackish colour and a few inches in thickness. In different districts it differs but little in appearance, although it may rest on various subsoils.
