The Formation of Vegetable Mould through the action of worms with observations of their habits

Darwin, Charles

A classic in naturalist observation. A grasp of the common earthworm’s importance is essential to a full understanding of soil fertility and plant health. Thanks to David Price for doing such an accurate scan of this book. Contains an interesting introduction by Sir Albert Howard, taken from a Faber & Faber edition, published about 1945.
