Earthworms are among the greatest
OF the agencies for soil irnpro wing. An.
gle worms move through the soil and
eat narrow hole. swallowing the earth.
In their stomachs, the grains of sand
are somewhat ground Up. In moist
countries, earthworms pass through
| their bodies each year about 10 tons
of dry earth per acre, making the soil
| fertile, allowing it 10 dry. and subject
ing 1t to the action Of the air. (See
| Darwin-Formatlon of Vegetable
Mould) In dry countries. the work OF
the earthworlns may not be wholly
beneficial. because they make the land
porous and IL thus becomes too dry.
Where the land surface Is too fiat for
rapid drainage, a deposit of humus or
peat is often formed Dry earth that
is porous burns up organic matter kept
under IL; hence. TO bury decaylng or.
ganlc matter beneath thin layer of
