It was not until the 6th, and after a continuation of the most incredible sufferings, already narrated, that the party reached Sutter's Fort, where, it is needless to say, they were warmly and cordially received by that gentleman,--and to close this stirring narrative, we will only add as an evidence of the terrible sufferings to which they had been subjected, that out of sixty-seven horses and mules with which the expedition was commenced, only thirty-three reached the valley of the Sacramento, and they had to be led. In quoting above from Fremont's narrative, a continuous record has not been kept, as we have used only such portions as contain the narrative of incidents directly connected with the expedition, and of which, though scarcely mentioned throughout, save in the most incidental manner, Carson might well say, and with pride, _magna pars fui_. In the course of this narrative we have frequently used the word _cache_, and a brief interpretation of its meaning, we are sure will not be uninteresting to the uninitiated. 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 any thing 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.
