October 23.—The damp raw weather, auguring the near approach of the autumnal rains, continues. A drizzling mist fell on us during the night, and the clouds were not dissipated when we resumed our voyage this morning. Passing through the straits of San Pablo and San Pedro, we entered a division of the bay called the bay of San Pablo. Wind and tide being in our favour, we crossed this sheet of water, and afterwards entered and passed through the Straits of Carquinez. At these straits the waters of the bay are compressed within the breadth of a mile, for the distance of about two leagues. On the southern side the shore is hilly, and canoned in some places. The northern shore is gentle, the hills and table-land sloping gradually down to the water. We landed at the bend of the Straits of Carquinez, and spent several hours in examining the country and soundings on the northern side. There is no timber here. The soil is covered with a growth of grass and white oats. The bend of the Straits of Carquinez, on the northern side, has been thought to be a favourable position for a commercial town. It has some advantages and some disadvantages, which it would be tedious for me now to detail.

[Subsequently to this my first visit here, a town of extensive dimensions has been laid off by Gen. Valléjo and Mr. Semple, the proprietors, under the name of "Francisca." It fronts for two or three miles on the "Soeson," the upper division of the Bay of San Francisco, and the Straits of Carquinez. A ferry has also been established, which crosses regularly from shore to shore, conveying travellers over the bay. I crossed, myself and horses, here in June, 1847, when on my return to the United States. Lots had then been offered to settlers on favourable conditions, and preparations, I understand, were making for the erection of a number of houses.]

About sunset we resumed our voyage. The Wind having lulled, we attempted to stem the adverse tide by the use of oars, but the ebb of the tide was stronger than the propelling force of our oars. Soon, in spite of all our exertions, we found ourselves drifting rapidly backwards, and, after two or three hours of hard labour in the dark, we were at last so fortunate as to effect a landing in a cove on the southern side of the straits, having retrograded several miles. In the cove there is a small sandy beach, upon which the waves have drifted, and deposited a large quantity of oat-straw, and feathers shed by the millions of water-fowls which sport upon the bay. On this downy deposit furnished by nature we spread our blankets, and slept soundly.

October 24.—We proceeded on our voyage at daylight, coasting along the southern shore of the Soeson. About nine o'clock we landed on a marshy plain, and cooked breakfast. A range of mountains bounds this plain, the base of which is several miles from the shore of the bay. These mountains, although of considerable elevation, exhibit signs of fertility to their summits. On the plain, numerous herds of wild cattle were grazing. About two o'clock, P.M., we entered the mouth of the Sacramento. The Sacramento and San Joaquin Rivers empty into the Bay of San Francisco at the same point, about sixty miles from the Pacific, and by numerous mouths or sloughs as they are here called. These sloughs wind through an immense timbered swamp, and constitute a terraqueous labyrinth of such intricacy, that unskilful and inexperienced navigators have been lost for many days in it, and some, I have been told, have perished, never finding their way out. A range of low sloping hills approach the Sacramento a short distance above its mouth, on the left-hand side as you ascend, and run parallel with the stream several miles. The banks of the river, and several large islands which we passed during the day, are timbered with sycamore, oak, and a variety of smaller trees and shrubbery. Numerous grape-vines, climbing over the trees, and loaded down with a small and very acid fruit, give to the forest a tangled appearance. The islands of the Sacramento are all low, and subject to overflow in the spring of the year. The soil of the river bottom, including the islands, is covered with rank vegetation, a certain evidence of its fertility. The water, at this season, is perfectly limpid, and, although the tide ebbs and flows more than a hundred miles above the mouth of the river, it is fresh and sweet. The channel of the Sacramento is remarkably free from snags and other obstructions to navigation. A more beautiful and placid stream of water I never saw.

At twelve o'clock at night, the ebb-tide being so strong that we found ourselves drifting backwards, with some difficulty we effected a landing on one of the islands, clearing a way through the tangled brush and vines with our hatchets and knives. Lighting a fire, we bivouacked until daylight.

October 25.—Continuing our voyage, we landed, about nine o'clock, A.M., at an Indian rancheria, situated on the bank of the river. An old Indian, his wife, and two or three children, were all the present occupants of this rancheria. The woman was the most miserable and emaciated object I ever beheld. She was probably a victim of the "sweat-house." Surrounding the rancheria were two or three acres of ground, planted with maize, beans, and melons. Purchasing a quantity of water and musk-melons, we re-embarked and pursued our voyage. As we ascended the stream, the banks became more elevated, the country on both sides opening into vast savannas, dotted occasionally with parks of evergreen oak.

The tide turning against us again about eleven or twelve o'clock, we landed at an encampment of Walla-Walla Indians, a portion of the party previously referred to, and reported to have visited California for hostile purposes. Among them was a Delaware Indian, known as "Delaware Tom," who speaks English as fluently as any Anglo-Saxon, and is a most gallant and honourable Indian. Several of the party, a majority of whom were women and children, were sick with chills and fever. The men were engaged in hunting and jerking deer and elk meat. Throwing our hooks, baited with fresh meat, into the river, we soon drew out small fish enough for dinner.

The specimens of Walla-Wallas at this encampment are far superior to the Indians of California in features, figure, and intelligence. Their complexion is much lighter, and their features more regular, expressive, and pleasing. Men and women were clothed in dressed skins. The men were armed with rifles.

At sunset we put our little craft in motion again, and at one o'clock at night landed near the cabin of a German emigrant named Schwartz, six miles below the embarcadero of New Helvetia. The cabin is about twenty feet in length by twelve in breadth, constructed of a light rude frame, shingled with tule. After gaining admission, we found a fire blazing in the centre of the dwelling on the earth-floor, and suspended over us were as many salmon, taken from the Sacramento, as could be placed in position to imbibe the preservative qualities of the smoke.

Our host, Mr. Schwartz, is one of those eccentric human phenomena rarely met with, who, wandering from their own nation into foreign countries, forget their own language without acquiring any other. He speaks a tongue (language it cannot be called) peculiar to himself, and scarcely intelligible. It is a mixture, in about equal parts, of German, English, French, Spanish, and rancheria Indian, a compounded polyglot or lingual pi—each syllable of a word sometimes being derived from a different language. Stretching ourselves on the benches surrounding the fire, so as to avoid the drippings from the pendent salmon, we slept until morning.
