in the shape of a jug, which is lined with dry sticks,
grass, or anything else that will protect its contents
from the dampness of the earth. In this place the goods
to be concealed are carefully stowed away; and the aperture
is then so effectually closed as to protect them from
the rains. In caching, a great deal of skill is often
required to leave no sign whereby the cunning savage may
discover the place of deposit. To this end, the excavated
earth is carried some distance and carefully concealed,
or thrown into a stream, if one be at hand. The place
selected for a cache is usually some rolling point,
sufficiently elevated to be secure from inundations.
If it be well set with grass, a solid piece of turf is
cut out large enough for the entrance. The turf is
afterward laid back, and, taking root, in a short time
no signs remain of its ever having been molested.
However, as every locality does not afford a turfy site,
the camp-fire is sometimes built upon the place, or the
animals are penned over it, which effectually destroys
all traces.

Father Hennepin[15] thus describes, in his quaint style, how he built
a cache on the bank of the Mississippi, in 1680:

We took up the green sodd, and laid it by, and digg'd a hole
in the Earth where we put our Goods, and cover'd them with
pieces of Timber and Earth, and then put in again the green
Turf; so that 'twas impossible to suspect that any Hole had
been digg'd under it, for we flung the Earth into the River.
