British Columbia has a length of 800 miles, and averages 400 miles in width. To whoever crosses the country it seems the scene of a vast earth-disturbance, over which mountains are scattered without system. In fact, however, the Cordillera belt is there divided into four ranges, the Rockies forming the eastern boundary, then the Gold Range, then the Coast Range, and, last of all, that partially submerged chain whose upraised parts form Vancouver and the other mountainous islands near the main-land in the Pacific. A vast valley flanks the south-western side of the Rocky Mountains, accompanying them from where they leave our North-western States in a wide straight furrow for a distance of 700 miles. Such great rivers as the Columbia, the Fraser, the Parsnip, the Kootenay, and the Finlay are encountered in it. While it has a lesser agricultural value than other valleys in the province, its mineral possibilities are considered to be very great, and when, as must be the case, it is made the route of communication between one end of the territory and the other, a vast timber supply will be rendered marketable. The Gold Range, next to the westward, is not bald, like the Rockies, but, excepting the higher peaks, is timbered with a dense forest growth. Those busiest of all British Columbian explorers, the "prospectors," have found much of this system too difficult even for their pertinacity. But the character of the region is well understood. Here are high plateaus of rolling country, and in the mountains are glaciers and snow fields. Between this system and the Coast Range is what is called the Interior Plateau, averaging one hundred miles in width, and following the trend of that portion of the continent, with an elevation that grows less as the north is approached. This plateau is crossed and followed by valleys that take every direction, and these are the seats of rivers and watercourses. In the southern part of this plateau is the best grazing land in the province, and much fine agricultural country, while in the north, where the climate is more most, the timber increases, and parts of the land are thought to be convertible into farms. Next comes the Coast Range, whose western slopes are enriched by the milder climate of the coast; and beyond lies the remarkably tattered shore of the Pacific, lapped by a sheltered sea, verdant, indented by numberless inlets, which, in turn, are faced by uncounted islands, and receive the discharge of almost as many streams and rivers--a wondrously beautiful region, forested by giant trees, and resorted to by numbers of fish exceeding calculation and belief. Beyond the coast is the bold chain of mountains of which Vancouver Island and the Queen Charlotte Islands are parts. Here is a vast treasure in that coal which our naval experts have found to be the best on the Pacific coast, and here also are traces of metals, whose value industry has not yet established.
