The Indians who then occupied these regions killed only what was required for the supply of the camps-a mere speck in the dense herds that roamed up to the very doors of the wigwams; but when the trader pushed his adventurous way into the fur regions of the North, the herds of the Saskatchewan plains began to experience a change in their surroundings. The meat, pounded down` and mixed with fat into "pemmican," was found to supply a most excellent food for transport service, and accordingly vast numbers of buffalo were destroyed to supply the demand of the fur traders. In the border-land between the wooded country and the plains, the Crees, not satisfied with the ordinary methods of destroying the buffalo, devised a plan by which great multitudes could be easily annihilated. This method of hunting, consists in the erection of strong wooden enclosures called pounds, into which the buffalo are guided by the supposed magic power of a medicine-man. Sometimes for two days the medicine-man will live with the herd, which he half guides and half drives into the enclosures; sometimes he is on the right, sometimes on the left, and sometimes, again, in rear of the herd, but never to windward of them. At last they approach the pound, which is usually concealed in a thicket of wood. For many miles from the entrance to this pound two gradually diverging lines of tree-stumps and heaps of snow lead out into the plains. Within these lines the buffalo are led by the medicine-man, and as the lines narrow towards the entrance, the herd, finding itself hemmed in on both sides, becomes more and more alarmed, until at length the great beasts plunge on into the pound itself, across the mouth of which ropes are quickly thrown and barriers raised. Then commences the slaughter. From the wooded fence around arrows and bullets are poured into the dense plunging mass of buffalo careering wildly round the ring. Always going in one direction, with the sun, the poor beasts race on until not a living thing is left; then, when there is nothing more to kill, the cutting-up commences, and pemmican-making goes on.
