The Formation of Vegetable Mould Through the Action
of Worms 1881
• In which we learn that worms are
indifferent to the sounds of shouting,
bassoons, and piano
• That the monoliths at Stonehenge are
being slowly buried by worms
• That worms can turn over mould at an
average rate of 5.6 mm/year
• And that in many parts of England
nearly 10 tons of dry earth passes
through their bodies annually!

“The plough is one of the most ancient and most
valuable of man’s inventions; but long before
he existed the land was in fact regularly
ploughed by earth-worms.” C. Darwin
