Mr. Hunt now set to work with all diligence, to prepare caches, in which to deposit the baggage and merchandise, of which it would be necessary to disburden themselves, preparatory to their weary march by land: and here we shall give a brief description of those contrivances, so noted in the wilderness.
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. Acircle 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 into the stream. After all this is done, the place is abandoned for the night, and, if all be right next morning, is not visited again, until there be a necessity for reopening the cache. Four men are sufficient, in this way, to conceal the amount of three tons weight of merchandise in the course of two days. Nine caches were required to contain the goods and baggage which Mr. Hunt found it necessary to leave at this place.
Three days had been thus employed since the departure of the several detachments, when that of Mr. Crooks unexpectedly made its appearance. A momentary joy was diffused through the camp, for they supposed succor to be at hand. It was soon dispelled.
Mr. Crooks and his companions had been completely disheartened by this retrograde march through a bleak and barren country; and had found, computing from their progress and the accumulating difficulties besetting every step, that it would be impossible to reach Henry's Fort and return to the main body in the course of the winter. They had determined, therefore, to rejoin their comrades, and share their lot.
One avenue of hope was thus closed upon the anxious sojourners at the Caldron Linn; their main expectation of relief was now from the two parties under Reed and M'Lellan, which had proceeded down the river; for, as to Mr. M'Kenzie's detachment, which had struck across the plains, they thought it would have sufficient difficulty in struggling forward through the trackless wilderness. For five days they continued to support themselves by trapping and fishing. Some fish of tolerable size were speared at night by the light of cedar torches; others, that were very small, were caught in nets with fine meshes. The product of their fishing, however, was very scanty. Their trapping was also precarious; and the tails and bellies of the beavers were dried and put by for the journey.
At length two of the companions of Mr. Reed returned, and were hailed with the most anxious eagerness. Their report served but to increase the general despondency. They had followed Mr. Reed for some distance below the point to which Mr. Hunt had explored, but had met with no Indians from whom to obtain information and relief. The river still presented the same furious aspect, brawling and boiling along a narrow and rugged channel, between rocks that rose like walls.
A lingering hope, which had been indulged by some of the party, of proceeding by water, was now finally given up: the long and terrific strait of the river set all further progress at defiance, and in their disgust at the place, and their vexation at the disasters sustained there, they gave it the indignant, though not very decorous, appellation of the Devil's Scuttle Hole.
