50 From Fort Smith there is an unobstructed run of about 1,300 miles, to Fort McPherson at the head of the delta of the Mackenzie, by way of Slave river, Great Slave lake, and Mackenzie river, and recent soundings have shown that the steamers that make this run could continue out to the Arctic ocean nearly 200 miles farther through one of the eastern channels of the Mackenzie. The steamers of the Hudson’s Bay Company, the Northern Trading Company, and Lampson and Hubbard Company make the trip to the delta of the Mackenzie once a season, but they are run on no regular schedule and solely for the convenience of these companies. The round trip is made in about four weeks. These boats each make a second trip later in the season either to Norman or Good Hope. This trip, made in August, is usually the last of the season, though navigation could be extended into September. Accommodation is provided for passengers on all these boats, but if travellers propose getting into the country away from the main line of travel on the Mackenzie river they must make their own arrangements for transportation up the tributaries of the Mackenzie. 7 Besides those water routes over which steamers now run and which have a total length of river and lake shore-line of about 3,600 miles, there are, in the northern section of the basin, navigable waterways tributary to Mackenzie river which have a total length of over 3,000 miles of river and lake shore-line. The whole system of waterways is divided naturally into four sections, each of which is separated from the adjoining one by natural obstructions or falls or heavy rapids which steamers cannot surmount. These sections are: (1) Atha- baska River section; (2) Peace River section; (8) Athabaska Lake section; and (4) Mackenzie River section.
