"The earth must be dry and sifted.
"Sand must not be used.
"No 'slops' must be thrown down.
"The handle must be pulled up with a jerk, and let fall sharply."
REPEATED USE OF EARTH
Concerning the value and use of the product of the earth-closet, the
following is copied from the London company's circular. (It will be
noticed that reference is made, to _the repeated use of the same
earth._ When the ordure is completely dried and decomposed, it has
not only lost its odor, but it has become, like all decomposed organic
matter, an excellent disinfectant, and the fifth or sixth time that
the same earth is passed through the closet it is fully as effective
in destroying odors as it was when used for the first time, and of
course each use adds to its value as manure, until it becomes as strong
as Peruvian guano, which is now worth seventy-five dollars per ton.
In fact, it may be made so rich that _one hundred pounds will be a
good dressing for an acre of land_.)
"If the closet is over a water-tight cesspool or pit, it will require
emptying at the end of three or six months. The produce, which will
be quite inodorous, should be thrown, together in a heap, sheltered
from wet, and occasionally turned over.
