78 Mackenzie’s Voyages the west to be Cook’s River, and that the body of water or sea into which this river discharges itself at Whale Island communicates with Norton Sound. I made an advantageous proposition to this man to accompany me across the moun- tains to the other river, but he refused it.” Mackenzie then proceeded to an Indian camp to which he had been referred for more authentic information. On arriving there he found that his young men in attempting to land had their canoe seized and broken and were on the point of revenging this insult when he intervened. The interpreter was instructed to harangue the people assembled in council for the purpose of obtaining further geographical information, but met with little success. Aside from the statement that the tributaries of both great rivers ! take their rise in the western mountains, their information was a strange medley of folk-lore and fact. They themselves never went beyond the mountains, where they hunted the little white buffalo? and what they stated about the river was hearsay and fabulous speculation. Mackenzie, however, suspected that his interpreter, who was tired of the voyage, was not anxious to obtain, or to communicate to him, information which would be likely to induce him to follow new routes, or extend his quest over another season. The assembled Indians then entertained the explorers with a series of dances. “In this pastime old and young, male and female, continued their exertions till their strength was exhausted. This exercise was accompanied by loud imitations of the various noises produced by the reindeer, the bear, and the wolf.” 1 It is difficult to say whether these Indians had any knowledge of the Yukon, or whether they were referring to Peel River. 2 Qyis dalli, a white variety of mountain sheep.
