"The climate of Idaho varies considerably with the degrees of latitude through which its limits extend, but not so much as would naturally be supposed from its great longitudinal extension; the isothermal lines of the Territory, running from east to west, have a well-defined northward variation, caused by the influence of air currents from the Pacific Ocean. Throughout the spring, summer, and autumn months, in the northern as well as the southern sections, the weather is generally delightful and salubrious; in the winter months the range of the thermometer depends greatly upon the altitude of the surface,--the higher mountains being visited by extreme cold and by heavy falls of snow; the lower mountain-ranges and the plains having winters generally less severe than those of northern Iowa and Wisconsin or central Minnesota, while greater dryness of the atmosphere renders a lower fall of the thermometer less perceptible; and the valleys being rarely visited by cold weather, high winds, or considerable falls of snow. Considered in its yearly average, the climate is exactly adapted to sheep-growing and the production of wool, the herding of cattle, and manufacture of dairy products, the raising of very superior breeds of horses, as well as the culture of all Northern varieties of fruits, such as apples, pears, plums, cherries, peaches, grapes, and all of the ordinary cereals and vegetables" (p. 164). This is all different from what we have conceived the Rocky Mountains to be. When the government reports of the explorations of 1853 were issued, Jeff Davis was Secretary of War, and he deliberately falsified the report of Governor Stevens's explorations from Lake Superior to the valley of the Columbia. Governor Stevens reported that the route passed through a region highly susceptible of agriculture; but the Secretary of War, even then plotting treason, in his summary of the advantages of the various routes, asserted that Governor Stevens had overstated the facts, and that there were not more than 1,000 square miles, or 640,000 acres, of agricultural lands. The Land Commissioner in his Report estimates the amount of agricultural lands at 16,925,000 acres. The amount of improved lands in Ohio in 1860 was 12,665,000 acres, or more than 4,000,000 less than the available agricultural lands in Idaho. These are lands that need no irrigation. Of such lands there are 14,000,000 acres, which, in the language of the Commissioner, are "redeemable by irrigation into excellent pasture and agricultural lands." The grazing-lands are estimated at 5,000,000 acres, the timbered lands at 7,500,000 acres, besides 8,000,000 acres of mineral lands. Although the population of Idaho probably does not exceed 50,000, half of whom are engaged in mining, the value of the agricultural products for 1868 amounted to $12,000,000, while the mineral product was $10,000,000. Passing on to Oregon we find a State containing 95,000 square miles, two and a half times larger than Ohio.
