with spruce-twigs, which had apparently been broken off by the weight of the snow. The summit was passed through an open space about twenty acres in extent. This glade was surrounded with a dense forest of spruce trees. There was no danger in walking except near the young trees, which had been bent down by the snow, but on passing these they often broke through, and experienced much difficulty in extricating themselves, particularly the poor Indians, with their heavy burdens. The breadth of snow passed over was about eight miles. At three o'clock they reached the Spipen [14] River, where they encamped: this camp was found to be two thousand five hundred and forty-one feet above the level of the sea. The vegetation appeared to our botanical gentlemen farther advanced on the east side than on the west, at the same height; the Pulmonarias and several small annuals were more forward. There were only a few pine trees, and those small, seen on the west side of the ridge; and on the east side, there was a species of larch, the hackmatack of the country. While they remained at this camp, they found a Pyrola, and some new ferns.
The country about the Spipen[14] is mountainous and woody, with a narrow strip of meadow-land along its banks. Mr. Waldron had, on arriving at the camp, sent Lachemere, one of the Indians, down the river to an Indian chief, in order to procure horses. Those that remained after providing for the baggage, were consequently assigned each to two or three individuals to ride and tye on their route.
On the 30th, they proceeded down the Spipen, making a journey of eighteen miles, and passed another branch of the river, the junction of which augmented its size very considerably. Its banks, too, became perpendicular and rocky, with a current flowing between them at the rate of six or seven miles an hour. After the junction, the stream was about one hundred feet broad, and its course was east-southeast.
The vegetation on the east side of the mountains was decidedly more advanced than that to the west, and several very interesting species of plants were met with by the botanists, on the banks of the streams: among them were Pæonia brownii, Cypripedium oregonium, Pentstemon, Ipomopsis elegans, and several Compositæ, and a very handsome flowering shrub, Purshia tridentata.
On the 31st, they continued their route over a rough country, in some places almost impassable for a horse from its steepness, and in others so marshy as to require much caution to prevent being mired.
During the morning, they met two Indians, who informed them that the chief of the Yakima tribe was a short distance in advance, waiting to meet them, and that he had several horses. At noon they reached a small prairie on the banks of the river, where old Tidias, the chief, was seen seated in state to receive Lieutenant Johnson; but this ceremony was unavoidably broken in upon by the necessity of getting the meridian observations. The chief, however, advanced towards him with every mark of friendship, giving the party a hearty welcome. In person he was tall, straight, and thin, a little bald, with long black hair hanging down his back, carefully tied with a worsted rag. He was grave, but dignified and graceful. When they had been seated, and after smoking a couple of pipes in silence, he intimated that he was ready for a talk, which then followed, relative to the rivers and face of the country; but little information was obtained that could be depended upon.
This tribe subsist chiefly upon salmon and the cammass-root: game is very scarce, and the beaver have all disappeared. The cammass-root is pounded and made into a sort of cake, which is not unpleasant, having a sweetish taste, but it is very dry, although some of the party took a fancy to it.
Tidias had with him an old man almost blind, who claimed much respect, and two young men, whose dress of buckskin, profusely ornamented with beads, was much admired by the party. During the talk, the old chief expressed himself delighted to see the white men, and spoke of his own importance, his immense territory, etc., in a style of boasting, to which the Indians are very much addicted. He said that he was desirous of affording all the accommodation he could to the party. But although he had eight or ten fine horses with him, he would not agree to part with them, as they were all his favourites. He was presented with a variety of articles, in return for which he gave the party a few dried salmon.
Towards evening, old Tidias took leave of them, saying that it was not proper for an Indian to encamp in the same place with a white man, and with a promise that he would have horses by ten o'clock the next day; but he had a game to play by procrastinating, in which he thoroughly succeeded.
In the morning they reached the Indian camp below, but no horses had arrived. It was far, they said, to Tidias's house; a man could not go thither and return in the same day; no horses or salmon could be brought; no one could be permitted to go. Lieutenant Johnson was then told that the road he had to follow was a "hungry" road. At last the Indian was induced by high offers to exchange good horses for a great number of bad ones, and finally consented to part with two more. On quitting him they became thoroughly aware that all the difficulties were owing, not to any indisposition to sell, but were created for the purpose of inducing high prices to be given.
The party now branched off at right angles to their former route, Lieutenant Johnson heartily sick and tired of his friend Tidias and his people. Two more of the Indians here left them. The country they entered, after passing a ridge about six hundred feet high, was quite of a different aspect, forming long sloping hills, covered with a scanty growth of pines. Many dry beds of rivulets were passed, and the soil of the hills produced nothing but a long thin grass. There are, however, some small valleys where the growth of grass is luxuriant, the pines are larger, and the scenery assumed a park-like appearance.
From the summit of one of the hills, a sketch of Mount Rainier, and of the intervening range, was obtained.
On the top of the ridge they fell in with a number of Spipen Indians, who were engaged in digging the cammass and other roots. The latter were those of an umbelliferous plant, oblong, tuberous, and in taste resembling a parsnip. The process used to prepare them for bread, is to bake them in a well-heated oven of stones; when they are taken out they are dried, and then pounded between two stones till the mass becomes as fine as corn meal, when it is kneaded into cakes and dried in the sun. These roots are the principal vegetable food of the Indians throughout Middle Oregon. The women are frequently seen, to the number of twenty or thirty, with baskets suspended from the neck, and a pointed stick in their hand, digging these roots, and so intently engaged in the search for them, as to pay no attention whatever to a passer-by. When these roots are properly dried, they are stored away for the winter's consumption. This day they made only fifteen miles, in a northern direction.
On the 2d of June, they reached the Yakima, after having crossed a small stream. The Yakima was too deep for the horses to ford with their packs, and they now for the first time used their balsas of India-rubber cloth, which were found to answer the purpose of floating the loads across the stream.
This river is one hundred and fifty feet wide, and pursues an east-southeast course, with a velocity of more than four miles an hour. At this place were found twenty migrating Indians, who have their permanent residence on the banks lower down.
The chief, Kamaiyah, was the son-in-law of old Tidias, and one of the most handsome and perfectly-formed Indians they had met with. He was found to be gruff and surly in his manners, which was thought to be owing to his wish to appear dignified. These Indians were living in temporary huts, consisting of mats spread on poles. Among them was seen quite a pretty girl, dressed in a shirt and trousers, with moccasins of skin very much ornamented with fringe and beads. They had a number of fine horses, but could not be induced to part with any of them.
Lieutenant Johnson had now succeeded in purchasing venison and salmon, and the party again had full allowance.
On the 3d, they continued their route to the northward, over gradually rising ground, and Lieutenant Johnson having succeeded in purchasing three more horses, only three of the party were now without them, so that the riding and tye system was not quite so often resorted to as before. On this plain was seen a number of curlews, some grouse, and a large species of hare. They encamped again near the snow, and found their altitude greater than any yet reached, the barometer standing at 24·750 in.: five thousand two hundred and three feet. They had again reached the spruces and lost the pine, which was only found on the hill-sides and plains.
At 4 a.m. on the morning of the 4th of June, the thermometer stood at 28°.
