WAPPATOO ISLAND AND ROOT.

Wappatoo Island is a large extent of country lying between the Multnomah River and an arm of the Columbia. The island is about twenty miles long, and varies in breadth from five to ten miles. The land is high, and extremely fertile, and on most parts is supplied with a heavy growth of cottonwood, ash, and willow. But the chief wealth of this island consists of the numerous ponds in the interior, abounding with the common arrowhead (Sagittaria sagittifolia), to the root of which is attached a bulb growing beneath it, in the mud. This bulb, to which the Indians give the name of wappatoo, is the great article of food, and almost the staple article of commerce, on the Columbia. It is never out of season; so that, at all times of the year, the valley is frequented by the neighboring Indians who come to gather it. It is collected chiefly by the women, who employ for the purpose canoes from ten to fourteen feet in length, about two feet wide, and nine inches deep, tapering from the middle, where they are about twenty inches wide. They are sufficient to contain a single person and several bushels of roots; yet so light, that a woman can carry one with ease. She takes one of these canoes into a pond where the water is as high as the breast, and, by means of her toes, separates from the root this bulb, which, on being freed from the mud, rises immediately to the surface of the water, and is thrown into the canoe. In this manner, these patient females remain in the water for several hours, even in the depth of winter. This plant is found through the whole extent of the valley in which we now are, but does not grow on the Columbia farther eastward.

SCENERY OF THE RIVER AND SHORES.

Above the junction of the Multnomah River, we passed along under high, steep, and rocky sides of the mountains, which here close in on each side of the river, forming stupendous precipices, covered with the fir and white cedar. Down these heights frequently descend the most beautiful cascades,—one of which, a large stream, throws itself over a perpendicular rock, three hundred feet above the water; while other smaller streams precipitate themselves from a still greater elevation, and, separating into a mist, again collect, and form a second cascade before they reach the bottom of the rocks.

The hills on both sides of the river are about two hundred and fifty feet high, generally abrupt and craggy, and in many places presenting a perpendicular face of black, hard, basaltic rock. From the top of these hills, the country extends itself, in level plains, to a very great distance.

To one remarkable elevation we gave the name of Beacon Rock. It stands on the north side of the river, insulated from the hills. The northern side has a partial growth of fir or pine. To the south, it rises in an unbroken precipice to the height of seven hundred feet, where it terminates in a sharp point, and may be seen at the distance of twenty miles. This rock may be considered as the point where tidewater commences.

April 19.—We formed our camp at the foot of the Long Narrows, a little above a settlement of Skilloots. Their dwellings were formed by sticks set in the ground, and covered with mats and straw, and so large, that each was the residence of several families.

The whole village was filled with rejoicing at having caught a salmon, which was considered as the harbinger of vast quantities that would arrive in a few days. In the belief that it would hasten their coming, the Indians, according to their custom, dressed the fish, and cut it into small pieces, one of which was given to every child in the village; and, in the good humor excited by this occurrence, they parted, though reluctantly, with four horses, for which we gave them two kettles, reserving to ourselves only one.

We resumed our route, and soon after halted on a hill, from the top of which we had a commanding view of the range of mountains in which Mount Hood stands, and which continued south as far as the eye could reach; their summits being covered with snow. Mount Hood bore south thirty degrees west; and another snowy summit, which we have called Mount Jefferson, south ten degrees west.

Capt. Clarke crossed the river, with nine men and a large part of the merchandise, to purchase, if possible, twelve horses to transport our baggage, and some pounded fish, as a reserve, on the passage across the mountains. He succeeded in purchasing only four horses, and those at double the price that had been paid to the Shoshonees.
