The Oregon territory is usually divided into three great divisions, the lower, middle, and upper regions. The upper includes the Rocky Mountains, with the head waters of most of the rivers running west and east, north and south, and extends west to the Blue and Spokan ranges of mountains. The lower includes the belt of country bounded on the west by the Pacific, and on the east by the Nesqually, Cascade, and California Mountains. The middle region lies between the two, and embraces probably far the greatest extent of country, and is in some respects the most desirable for settlers.

The number of rainy days, during the winter season, in the lower country, is thought to be about eighty-five one-hundredths; while the number of rainy days during the same season in the upper (or middle) country, is about fifteen one-hundredths. {166} There is but little more snow during the winter season in the middle than in the lower region of the Columbia river, or upon the plains. Of course the depth of snow upon the mountains, depends upon their height.

The lower country is subject to inundations, to a greater or less extent, from the Columbia river, which gathering into standing pools, with the great amount of vegetable decay consequent upon low prairie countries, produces to some extent unhealthy fogs during the summer season. This, however, is greatly moderated by the sea breezes from the Pacific. The middle region is entirely free from these evils, and has probably one of the most pacific, healthy, and every way most desirable climates in the world. This, with its extensive prairies, covered with a superior quality of grass tuft, or bunch grass, which springs fresh twice a year, and spotted and streaked everywhere with springs and streams of the purest, sweetest water, renders it admirably adapted to the herding system. The lower country will ever have greatly the advantage in its proximity to market, its extensive sea coast, and from the fact that it contains one of the largest and best harbors in the world, viz. Puget's sound, running far inland, the mouth of which is protected by Vancouver's island, easy of access at all seasons and under all winds.

But to go into detail. Myself and wife were appointed missionaries by the American Board of Commissioners for Foreign Missions, and destined to this field, and with our worthy associates, Dr. Whitman, and lady, arrived in this country in the fall of 1836. The Doctor settled among the Cayuses near fort Wallawalla, and myself at this place, where we have ever since continued to dwell. Our duties have called us to travel more or less every year to visit the distant bands and tribes, as also to pack our supplies. I have traversed this middle region in seventeen different routes, of from 60 to 300 miles. Over many of the routes I have passed probably in every month in the year, have marked the progress of vegetation from its earliest shooting forth; the effects of this climate {167} upon the animal constitution; the rapidity with which exhausted poor animals regain their flesh and activity, when turned upon the plains; and have kept tables under some of these heads, as also a meteorological table for several years.

Let me here observe that my views of the country have been materially changed by a more accurate acquaintance with its true nature. I once thought the valleys only susceptible of habitation; considering the plains too dry for cultivation. But I am now prepared to say this is not the case. The plains suffer far less from drought than the valleys, on account of the reflection of heat from the surrounding hills. The country, however, is nowhere peculiarly subject to drought, as was once thought. My place is one of the deepest valleys, and consequently the most exposed to the reflection from the high bluffs around, which rise from two to three thousand feet; but my farm, though prepared for irrigation, has remained without it for the last four years. I find the ground becomes more moist by cultivation. Three years ago I raised six hundred bushels of shelled corn from six acres, and good crops of wheat on the same piece the two following years, without irrigation. Eight years ago I raised 1500 bushels of potatoes from one acre and a half; measuring some of the bags in which they were brought to the cellars, and so judging of the whole amount. I gave every eleventh bag for digging and fetching, and kept a strict account of what every person brought, so that I was able to make a pretty accurate estimate of the whole amount. My potatoes and corn are always planted in drills.

Every kind of grain or vegetable which I have tried or seen tried in this upper country, grows well. Wheat is sown in the fall, and harvested in June at this place; at Dr. Whitman's in July, being a more open country. Corn is planted in April and ripens in July; peas the same.

EXTENT OF COUNTRY

The southern boundary of Oregon territory is the 42d degree of north latitude. The northern boundary is not yet settled;[222] {168} both England and The United States claim north of the Columbia river to latitude 49°. But this vast fertile region, well timbered upon the mountains and river sources, and well watered, besides having the fine harbor above named, Puget's sound, must ever remain the most important portion of Oregon, especially on account of this harbor, which will naturally control these seas, and consequently the country. Should the British flag finally exclusively wave over its placid waters, it will be to the rest of Oregon as Quebec is to Canada, or Gibraltar to the Mediterranean. Vancouver's Island is doubtless another reason why Great Britain wishes to make the Columbia river her northern boundary. The line of 49° passes a little north of the southern half of the island. The whole island contains a territory considerably larger than England and Scotland, produces every kind of grain and vegetable well, and has a climate very similar to our Middle and Southern states. Whatever nation possesses this island, or the south portion of it, with its neighboring harbor, Puget's sound, possesses nearly all of a national consideration which pertains to Oregon, and will consequently control it. But if this island, or this portion of it, with this harbor, add their ever controlling influence to the undivided interests of Oregon, this young colony, but yesterday begun, and whose country and existence were but yesterday disputed, will at no distant day, under the softening, life-giving influence of civilization and our holy religion, take its place among the wealthiest, happiest, and best nations of the earth.

The country of Oregon, should it extend to 49° north latitude, is probably capable of sustaining as great a population as two-thirds of the territory of the States, and with far less hard labor.
