Whilst taking our ease at Kamloops it may be well to consider the question of the practicability of a road across the mountains by the Yellow Head, or Leather Pass. The necessity for opening a communication between the eastern and western sides of the Rocky Mountains, and the advantages of a route across the continent which passes through British territory, will, we apprehend, appear clearly enough upon a more intimate acquaintance with the resources and requirements of British Columbia. At present we wish merely to show that a road might be constructed by the Yellow Head Pass without any great difficulty, and that this route is in many respects superior to others hitherto more generally known. In the first place, then, we may safely state that, with the exception of one or two rocky and precipitous bluffs-- few and trifling obstructions, compared with those which have been so successfully overcome in making the road along the Fraser--there are no engineering difficulties of any importance. From the Red River Settlement to Edmonton, about 800 miles, the road lies through a fertile and park-like country, and an excellent cart trail already exists. From Edmonton to Jasper House, a distance of about 400 miles, the surface is slightly undulating, the lower ground universally swampy, and everywhere covered with thick forest. There is little doubt that a better trail than the one at present used might be found for this portion of the way, by keeping to the higher ground, for the pioneers of the Hudson’s Bay Company sought the swamps in the first instance, as offering fewer impediments to their progress, on account of their being less heavily timbered. From Jasper House to Tête Jaune Cache--the pass through the main ridge of the Rocky Mountains, about 100 or 120 miles in length--a wide break in the chain, running nearly east and west, offers a natural roadway, unobstructed except by timber. The rivers, with the exception of the Athabasca and the Fraser, are small and fordable; even at their highest. The ascent to the height of land is very gradual, and, indeed, hardly perceptible; the level only 3,760 feet above the sea;[11] and the descent on the western slope, although more rapid, is neither steep nor difficult. From The Cache the road might be carried in almost a straight line to Richfield, in Cariboo, lying nearly due west; the western extremity of the pass, Tête Jaune Cache, being in latitude 52 deg. 58 min.,[12] and Richfield in latitude nearly 53 deg. 3 min. 9 sec.[13] The region to be traversed is mountainous and densely wooded, but the distance is not more than ninety miles, according to the recent calculation of Dr. Rae, which agrees with the six days’ journey, the estimate given us by the Shushwaps of The Cache; and a road has already been made from the Mouth of Quesnelle, on the Fraser, to Richfield, through similar country. This would, therefore, complete the line of communication through Cariboo to Victoria.
