The following abstract of Commander Wilkes’ Report on Oregon came to hand while this work was in the press, and the author takes great pleasure in appending it to his work. Mr. Wilkes’ statistics of the Territory, it will be seen, agree in all essential particulars with those given in previous pages. There is one point only of any importance that needs to be named, in regard to which truth requires a protest; and that is contained in the commander’s concluding remarks. It will be seen on reference to them, that the agricultural capabilities of Oregon are placed above those of any part of the world beyond the tropics. This is a most surprising conclusion; at war with his own account of the several sections which he visited, and denied by every intelligent man living in the territory. What! Oregon, in this respect, equal to California, or the Valley of the Mississippi! This can never be, until Oregon be blessed with a vast increase of productive soil, and California {276} and our own unequalled Valley be greatly changed. _Extracts from the Report of Lieutenant Wilkes to the Secretary of the Navy, of the examination, by the Exploring Expedition, of the Oregon Territory._[88] The Territory embraced under the name of Oregon, extends from latitude 42° north to that of 53° 40′ north, and west of the Rocky Mountains. Its natural boundaries, were they attended to, would confine it within the above geographical boundaries. On the east it has the range of Rocky Mountains along its whole extent; on the south those of the Klamet range, running on the parallel of 42° and dividing it from California; on the west the Pacific Ocean; and on the north the western trend of the Rocky Mountains, and the chain of lakes near and along the parallels of 54° and 55° north, dividing it from the British territory. It is remarkable that, within these limits, all the rivers which flow through the Territory take their rise. The Territory is divided into three natural belts or sections, viz: {277} 1st. That between the Pacific Ocean and Cascade Mountains, (President’s range) or western section; 2nd. That between the Cascade mountains and blue mountain range, or middle section; 3rd. That between the Blue and Rocky Mountain chains, or eastern section. And this division will equally apply to the soil, climate, and productions. The mountain ranges run, for the most part, in parallel lines with the coast, and, rising in many places above the snow line (here found to be 6,500 feet), would naturally produce a difference of temperature between them, and also affect their productions. Our surveys and explorations were confined, for the most part, to the two first, claiming more interest from being less known, and more in accordance with my instructions.
