This stream has two principal branches; the one rising in the Coast Range, runs for twenty miles in a south-easterly direction, through a beautiful and fertile valley of twelve miles in width, handsomely covered with groves of white oak, and other timber; which is intersected with numerous spring branches, the banks of which are lined with timber, leaving in some places fine bottom prairies, covered with a rich sward of grass. Between this fork and the Shahalam is a range of hills averaging about two miles in width, extending from a part of the Coast Range, to within three miles of the Willamette. They are of steep ascent, some of them rising to five or six hundred feet in height, well covered with grass, and from their sides issue numerous spring rivulets, which near their origin are lined with fir trees; thence passing through groves of white oak, alder and willow, to the bottom lands, which in crossing some of them disappear, and others after joining together, continue their courses until they unite with the Shahalam and Yam-hill. The grasses on these hills are a species of red clover, that grows in the summer season about one foot high, and a fine grass, which after the clover disappears, keep them clad in green during the winter. Thus they furnish a perpetual supply of food for cattle the whole year. The soil upon these hills is a mixture of clay and loam, of a reddish color, and in the bottoms it is a rich {92} mixture of loam and muck. However, there are some of the hills somewhat sandy, and occasionally interspersed with stony places.

From the source of this branch of the Yam-hill, (which in the country is called the North Fork,) passes the trace, along which the people on Clatsop plains drive their cattle a distance of about forty miles, when they reach the coast, fifteen miles south of Cape Lookout.

The south fork of Yam-hill has its source in the Coast Range; where it emerges from the mountains, for the first ten miles, its banks are well supplied with large fir trees, as are its several tributaries; its banks are generally steep, bearing the appearance of having washed out a channel from fifteen to twenty feet in depth. It runs an eastern course for about ten miles, then northeast for some miles, and finally takes a northern direction, until it connects with the North fork, near the Falls, after having flowed a distance of about twenty-five miles.

The valley watered by this stream is about fifteen miles wide, after the stream emerges from the heavy growth of firs already noticed; for there are firs, more or less, its whole length. From the water courses, upon an average of a little over one fourth of a mile, the valley is fine prairie land, soil light and rich, occasionally interspersed with fine groves, and well adapted to agricultural purposes. It is well covered with grass, as is every portion of the country that has oaken groves, and the lower bottoms yield an abundant supply of the Camas, a tuberous rooted plant, shaped something like an onion, which it resembles in appearance. It is devoured greedily by hogs, and affords very good nutriment. The Indians make much use of it as an article of food. Between these streams and within six miles of their junction, commences the high lands of the Coast Range; the first plateau is about ten miles wide, and well covered with grass. The second plateau, for a few miles is fern openings, with an occasional grove of timber; after this westward to the coast the country is heavily timbered with firs, pine, and occasionally cedar, hemlock, balsam, and nearly all species of the evergreen timber. The streams last described furnish good sites for hydraulic purposes, near the mountains. A considerable portion of the valley of the Yam-hill is not only claimed, but settled, and finely improved.[141]

Leaving the Yam-hill and ascending the Willamette twenty-five miles, we reach the mouth of the Rickerall, a stream {93} which has its source in the same range as the Yam-hill; for the first ten miles it runs rapidly over a pebbly bed, and from thence to the mouth has a deep channel, worn in a rich soil, with timbered banks. It flows in an easterly course from the mountains eighteen miles, and unites with the Willamette. The valley through which this stream flows resembles that described as watered by the Yam-hill; perhaps the soil is a little richer. It is nearly all claimed, and will soon be well settled. Upon this stream there is erected a grist mill, and there was a saw mill, but the freshets washed it away last spring.[142] Five miles above Yam-hill commence a range of hills that extend south to the Rickerall, similar to those between Shahalam and Yam-hill. These hills vary from one to four miles in width, leaving a bottom about six miles wide to skirt the Willamette, which is of good soil, well watered and timbered. Upon the slopes of these hills are several thousands of acres of white oak, from six to twenty feet in height, some of them of large diameter and all with large and bushy tops; the ground being covered with grass, at a distance they look like old orchards. The timber of these trees is very solid, and promises great durability.[143] The valley between the Yam-hill and Rickerall is called the Applegate settlement; there are three brothers of the Applegates, they have fine farms, with good herds of fat and thrifty cattle.[144] The Yam-hill plains is called the Hemerey settlement, from a family of this name there settled.[145]

Upon the Rickerall are the Gillams, Fords and Shaws, all doing well.[146] The Gays and Matheneys are settled upon the bottom of the Willamette, between Yam-hill and Rickerall.[147]

Twelve miles above the Rickerall, empties the Lucky muke into the Willamette; it heads in the same range as the Yam-hill, and, like it, has two principal branches, of about the same length, depth and width, and passes through an excellent valley of land, with the same diversities and excellent qualities for farming which are attributed to the Yam-hill valley—the timber being more of oak and less of fir. Upon this stream several claims are entered, and there is a fine opening for others who may desire to settle there.

Mouse river joins the Willamette about thirty-five miles above the Lucky-muke.[148] It has its origin in the Coast range, has two principal branches, which unite near the mountains, passes ten miles over a pebbly bottom, and then becomes more sluggish to its mouth. This, like the other streams described, {94} has timber upon its borders, but less than some; good country, fine prospects, and but few claims made.
