82 Mackenzie’s Voyages the idea of ascending these western mountains while he had the opportunity. There may have been a half-formed thought in his mind that by attaining the summit, the river in the west would open out to view. The distance to the Pacific was greatly foreshortened on all maps of the day. But the size, volume and direction of the Liard must have convinced him that it drained an extent of country westward greater than that indicated on the maps of that time. Leaving camp at four in the afternoon, Mackenzie with a young Indian set off through the woods towards the range in the west. The forest was difficult to penetrate. Coming out at last to rising ground they obtained their first view, since leaving the canoe, of the mountains which appeared to be as far off as ever. Proceeding, the travellers ran into marshy ground which effectually halted their pro- gress, and they were reluctantly compelled to return, reaching the canoes at midnight. The hunters reported coming upon Indian camps, and Mackenzie asked English Chief to search for the natives, but he was backward in complying. Mackenzie was evidently greatly dissatisfied with the meagre information that he had so far been able to secure, relating to the existence of a river flowing westward to the ocean. Ever since leaving the delta the suspicion had been growing in his mind that the Indians along the river knew more than they communicated, and that English Chief communicated less than he heard. “They were afraid that I should obtain such accounts of the other river as would induce me to travel overland to it, and that they should be called upon to accompany me. I was indeed informed by one of my own people, that English Chief, his wives and companions had determined to leave me on this side of Slave Lake in order to go to the country of the Beaver Indians.”
