One of the principal sources of subsistence of these frontier people in their long journeys through uninhabited regions was pemmican. This food was especially adapted to extreme northern countries, where in the winter it was sometimes impossible to make fires to cook with, and the means of transportation was by dog-trains, as it was equally good for man and beast. It was invented among the Hudson Bay people, many years ago, and undoubtedly from necessity. It was made in this way: The meat of the buffalo, without the fat, was thoroughly boiled, and then picked into shreds or very small pieces. A sack was made of buffalo skin, with the hair on the outside, which would hold about ninety pounds of meat. A hole was then dug in the ground of sufficient size to hold the sack. It was filled with the meat thus prepared, which was packed and pounded until it was as hard as it could be made. A kettle of boiling hot buffalo fat, in a fluid state, was then poured into it, until it was thoroughly permeated, every interstice from center to circumference being filled, until it became a solid mass, perfectly impervious to the air, and as well preserved against decomposition as if it had been enclosed in an hermetically sealed glass jar. Here you had a most nutritious preparation of animal food, all ready for use for both man and dog. An analysis of this compound proved it to possess more nutriment to the pound weight than any other substance ever manufactured, and with a winter camp appetite, it was a very palatable dish. Its great superiority over any other kind of food was its not requiring preparation and its portability. TRANSPORTATION AND EXPRESS.
