All that is necessary is to have a supply of coarsely sifted
sun-dried earth with which to cover the bottom of the vessel to be
used, and after use to cover the deposit. A small box of earth, and
a tin scoop are sufficient to prevent the gravest annoyance of the
sickroom. But, of course, for constant use, it is desirable to have
a more convenient apparatus--something which requires less care, and
is less troublesome in many ways.
To this end, the patent invention of Mr. Moule is applicable. This
comprises a tight receptacle under the seat, a reservoir for storing
dry earth, and an apparatus to measure out the requisite quantity, and
throw it upon the deposit.
[Illustration: Fig. 67.]
The arrangement at the mechanism is shown in Fig. 67. A hopper-shaded
reservoir, made of galvanized iron, is supported by a framework at the
back of the seat, which rests on the framework _a_, _a_. Connected with
the handle at the right-hand side, there is an iron lever, which
operates a movable box at the bottom of the reservoir, and causes it to
discharge its contents directly under the seat. When the handle is
dropped, the box returns to its position, and is immediately filled
preparatory to another use.
