148 Mackenzie’s Voyages supplies of salmon, after tedious parleying, and many alarums and excursions, entered into friendly communication with them, imparting the information that the river flowed south to the sea where white people were building houses. In three places it was impassable. The current was everywhere strong, while in the places mentioned it was impossible either to run the rapids or pass over the mountains which rose sheer from the water. The inhabitants were numerous; one tribe particularly which lived in underground houses * was described as being malignant. The explorers were warned against going any farther, their informants stating that those below were armed and would undoubtedly destroy them. In the course of the day they met other parties lower down who confirmed these reports, and added that the distance to the sea overland was comparatively short, and that a well-beaten path led to a river which emptied into a “lake”? whose waters were nauseous. White men in big vessels as large as islands came there and traded iron and various articles for the furs and skins which these inland natives were in the habit of carrying to the coast, over the road mentioned, Mackenzie himself thought that the distance overland could not be more than five or six degrees. He recalled Captain John Meares’ statement regarding the inland extension of the sea at Nootka, which Mackenzie thought must reach as far east as 126° west longitude. What his own expectations were he does not disclose. According to the account of the Indians the overland route from the 1The interior Salish tribes, like the Lillooets, Thompsons and Shuswaps, lived in circular, semi-subterranean houses excavated in the dry soil, some of which were sixty feet in diameter, and capable of housing thirty people. From December to March they thus gained a certain amount of protection from the cold.
