A cache is a term common among traders and hunters, to designate a hiding-place for provisions and effects.  It is derived from the French word “cacher”, to conceal, and originated among the early colonists of Canada and Louisiana; but the secret depository which it designates was in use among the aboriginals long before the intrusion of the white men.  It is, in fact, the only mode that migratory hordes have of preserving their valuables from robbery, during their long absences from their villages or accustomed haunts, on hunting expeditions, or during the vicissitudes of war.  The utmost skill and caution are required to render these places of concealment invisible to the lynx eye of an Indian.  The first care is to seek out a proper situation, which is generally some dry, low, bank of clay, on the margin of a water-course.  As soon as the precise spot is pitched upon, blankets, saddle-cloths, and other coverings are spread over the surrounding grass and bushes, to prevent foot-tracks, or any other derangement; and as few hands as possible are employed.  A circle of about two feet in diameter is then nicely cut in the sod, which is carefully removed, with the loose soil immediately beneath it, and laid aside in a place where it will be safe from anything that may change its appearance.  The uncovered area is then digged perpendicularly to the depth of about three feet, and is then gradually widened so as to form a conical chamber six or seven feet deep.  The whole of the earth displaced by this process, being of a different color from that an the surface, is handed up in a vessel, and heaped into a skin or cloth, in which it is conveyed to the stream and thrown into the midst of the current, that it may be entirely carried off.  Should the cache not be formed in the vicinity of a stream, the earth thus thrown up is carried to a distance, and scattered in such manner as not to leave the minutest trace.  The cave, being formed, is well lined with dry grass, bark, sticks, and poles, and occasionally a dried hide.  The property intended to be hidden is then laid in, after having been well aired:  a hide is spread over it, and dried grass, brush, and stones thrown in, and trampled down until the pit is filled to the neck.  The loose soil which had been put aside is then brought and rammed down firmly, to prevent its caving in, and is frequently sprinkled with water, to destroy the scent, lest the wolves and bears should be attracted to the place, and root up the concealed treasure.  When the neck of the cache is nearly level with the surrounding surface, the sod is again fitted in with the utmost exactness, and any bushes, stocks, or stones, that may have originally been about the spot, are restored to their former places.  The blankets and other coverings are then removed from the surrounding herbage; all tracks are obliterated; the grass is gently raised by the hand to its natural position, and the minutest chip or straw is scrupulously gleaned up and thrown
