The routes of ancient traffic, determined in part by the geographical contour of the regions through which they pass, are familiar to the historical students in the Old World. The ancient lines traversed by the traders between the Persian Gulf and the Levant; the routes of caravans by way of the oases, across the centre of the Arabian peninsula to the Red Sea; the lines of access by road and river from the Baltic to the Danube; and from the British Isles and the North Sea, by the valley of the Rhone, to the Mediterranean: are all indicated by a variety of evidence. The geography of Central Africa appears to have been familiar to the Arabian traders from remote ages. Similar well-trodden routes, and traverses by lake and river, are well known to the investigators of American antiquity. The great trail across Pennsylvania to the Mississippi; the route by the great lakes and by portage to the Hudson valley, and so to the Atlantic; from Lake Ontario, by the Humber and Lake Simcoe, to the Georgian Bay; from Lake Superior, by the Mitchipicotten river, to the Hudson Bay; and by the Mississippi and its tributaries to the Gulf of Mexico: are all demonstrated by abundant traces of the interchange of the products of widely severed regions, as disclosed in ancient burial mounds, and deposits assignable to remote periods and to long-extinct races. West of the Rocky Mountains the trails from the Pacific coast to the interior, and through the passes of that lofty range, have been recovered. Owing to the bold contours of the region, in the abrupt descent from the western slope of the Rocky Mountains to the Pacific, the routes of travel are more strictly defined by the physical geography of the country than in the long stretches of the continent to the east of that mountain range. An interchange of commodities between the tribes of the coast and the interior appears to have been carried on from remote times. Dr. Dawson’s own personal observations in British Columbia have satisfied him that trading intercourse was prosecuted by the coast tribes with those of the interior, along the Fraser River Valley; Bella Coola Valley, from head of Benetinck Arm; Skeena River; Stiking River; and Chilkoot Pass, from the head of Lynn Canal. By the second of the above routes oolacten oil was carried far into the interior; and the old trail leading from Bella Coola and Fraser river is chiefly associated by the inland Indians with this traffic. The habitual traffic engendered by the local advantages of some of the tribes on the northern Pacific coast has manifestly developed some peculiarities which distinguish them from other Indians of the northern continent. The Bilqula, a people inhabiting a limited tract in the vicinity of Dean Inlet and Benetinck Arms, by reason of their geographical position have held command of the most important natural pass and trade route from the ocean to the interior between the Skeena and the Fraser rivers, a distance of upwards of 400 miles.
