The disastrous surprisal of this hunting party is cited by Captain Bonneville to show the importance of vigilant watching and judicious encampments in the Indian country.

At length his horses having recovered strength sufficient for a journey, he prepared to return to the Nez Perces, or rather to visit his caches on Salmon River; that he might take thence goods and equipments for the opening season. Accordingly, leaving sixteen men at Snake River, he set out on the 19th of February with sixteen others on his journey to the caches.

On the 21st he was again floundering through the snow, on the great Snake River plain, where it lay to the depth of thirty inches. It was sufficiently incrusted to bear a pedestrian, but the poor horses broke through the crust, and plunged and strained at every step. So lacerated were they by the ice that it was necessary to change the
