CHAPTER XVIII.
Situation of the Columbia River.—Qualities of its Soil.—Climate, &c.—Vegetable and Animal Productions of the Country.
The mouth of the Columbia river is situated in 46° 19' north latitude, and 125° or 126° of longitude west of the meridian of Greenwich. The highest tides are very little over nine or ten feet, at its entrance, and are felt up stream for a distance of twenty-five or thirty leagues.
During the three years I spent there, the cold never was much below the freezing point; and I do not think the heat ever exceeded 76°. Westerly winds prevail from the early part of spring, and during a part of the summer; that wind generally springs up with the flood tide, and tempers the heat of the day. The northwest wind prevails during the latter part of summer and commencement of autumn. This last is succeeded by a southeast wind, which blows almost without intermission from the beginning of October to the end of December, or commencement of January. This interval is the rainy season, the most disagreeable of the year. Fogs (so thick that sometimes for days no object is discernible for five or six hundred yards from the beach), are also very prevalent.
The surface of the soil consists (in the valleys) of a layer of black vegetable mould, about five or six inches thick at most; under this layer is found another of gray and loose, but extremely cold earth; below which is a bed of coarse sand and gravel, and next to that pebble or hard rock. On the more elevated parts, the same black vegetable mould is found, but much thinner, and under it is the trap rock. We found along the seashore, south of Point Adams, a bank of earth white as chalk, which we used for white-washing our walls. The natives also brought us several specimens of blue, red and yellow earth or clay, which they said was to be found at a great distance south; and also a sort of shining earth, resembling lead ore.[V] We found no limestone, although we burnt several kilns, but never could get one ounce of lime.
We had brought with us from New York a variety of garden seeds, which were put in the ground in the month of May, 1811, on a rich piece of land laid out for the purpose on a sloping ground in front of our establishment. The garden had a fine appearance in the month of August; but although the plants were left in the ground until December, not one of them came to maturity, with the exception of the radishes, the turnips, and the potatoes. The turnips grew to a prodigious size; one of the largest we had the curiosity to weigh and measure; its circumference was thirty-three inches, its weight fifteen and a half pounds. The radishes were in full blossom in the month of December, and were left in the ground to perfect the seeds for the ensuing season, but they were all destroyed by the ground mice, who hid themselves under the stumps which we had not rooted out, and infested our garden. With all the care we could bestow on them during the passage from New York, only twelve potatoes were saved, and even these so shrivelled up, that we despaired of raising any from the few sprouts that still gave signs of life. Nevertheless we raised one hundred and ninety potatoes the first season, and after sparing a few plants for our inland traders, we planted about fifty or sixty hills, which produced five bushels the second year; about two of these were planted, and gave us a welcome crop of fifty bushels in the year 1813.
It would result from these facts, that the soil on the banks of the river, as far as tide water, or for a distance of fifty or sixty miles, is very little adapted for agriculture; at all events, vegetation is very slow. It may be that the soil is not everywhere so cold as the spot we selected for our garden, and some other positions might have given a better reward for our labor: this supposition is rendered more than probable when we take into consideration the great difference in the indigenous vegetables of the country in different localities.
The forest trees most common at the mouth of the river and near our establishment, were cedar, hemlock, white and red spruce, and alder. There were a few dwarf white and gray ashes; and here and there a soft maple. The alder grows also to a very large size; I measured some of twelve to fifteen inches diameter; the wood was used by us in preference, to make charcoal for the blacksmith's forge. But the largest of all the trees that I saw in the country, was a white spruce: this tree, which had lost its top branches, and bore evident marks of having been struck by lightning, was a mere, straight trunk of about eighty to one hundred feet in height; its bark whitened by age, made it very conspicuous among the other trees with their brown bark and dark foliage, like a huge column of white marble. It stood on the slope of a hill immediately in the rear of our palisades. Seven of us placed ourselves round its trunk, and we could not embrace it by extending our arms and touching merely the tips of our fingers; we measured it afterward in a more regular manner, and found it forty-two feet in circumference. It kept the same size, or nearly the same, to the very top.
