I think of the country which those who are going west will see, and of the region beyond,--the valley of the Yellowstone, the Missouri, the slopes of the Rocky Mountains, and the hills of Montana,--territory to be included in the future Empire of the Northwest. I have written the word, but it bears no political meaning in these notes. It has the same signification as when applied to the State of New York. The Empire of the Northwest will be the territory lying north of the central ridge of the continent. Milwaukie may be taken as a starting-point for a survey of this imperial domain. That city is near the 43d parallel; following it westward, we see that it passes over the mountain-range on whose northern slopes the southern affluents of the Yellowstone take their rise. All the fertile valleys of the Columbia and its tributaries lie north of this parallel; all the streams of the Upper Missouri country, and the magnificent water-system of Puget Sound, and the intricate bays and inlets of British Columbia, reaching on to Alaska, having their only counterpart in the fiords of Norway, are north of that degree of latitude. I have already taken a view of the region now comprised in the British dominions east of the Rocky Mountains; but equally interesting will be a review of the territories of the Republic,--Dakota, Montana, Idaho, Oregon, and Washington, also British Columbia and Vancouver. Dakota contains a little more than a hundred and fifty thousand square miles,--nearly enough territory to make four States as large as Ohio. "The climate and soil of Dakota," says the Commissioner of Public Lands, General Wilson, in his Report for 1869, "are exceedingly favorable to the growth of wheat, corn, and other cereals, while all the fruits raised in the Northern States are here produced in the greatest perfection.... The wheat crop varied from twenty to forty bushels to the acre. Oats have produced from fifty to seventy bushels to the acre, and are of excellent quality" (p. 144). Settlements are rapidly extending up the Missouri, and another year will behold this northern section teeming with emigrants. The northern section of the territory is bare of wood, but the southern portion is well supplied with timber in the Black Hills. Two thousand square miles of the region of the Black Hills, says Professor Hayden, geologist to the United States Exploring Expedition under General Reynolds, is covered with excellent pine timber. That is an area half as large as the State of Connecticut, ample for the southern section; while the settlers of the northern portion will be within easy distance by rail of the timbered lands of Minnesota.
