Continuing down the river, we encamped at noon on the 14th, at its mouth, on the Arkansas river. A short distance above our encampment, on the left bank of the Arkansas, is a pueblo, (as the Mexicans call their civilized Indian villages,) where a number of mountaineers, who had married Spanish women in the valley of Taos, had collected together and occupied themselves in farming, carrying on at the same time a desultory Indian trade. They were principally Americans, and treated us with all the rude hospitality their situation admitted; but as all commercial intercourse with New Mexico was now interrupted, in consequence of Mexican decrees to that effect, there was nothing to be had in the way of provisions. They had, however, a fine stock of cattle, and furnished us an abundance of excellent milk. I learned here that Maxwell, in company with two other men, had started for Taos on the morning of the 9th, but that he would probably fall into the hands of the Utah Indians, commonly called the Spanish Yutes. As Maxwell had no knowledge of their being in the vicinity when he crossed the Arkansas, his chance of escape was very doubtful; but I did not entertain much apprehension for his life, having great confidence in his prudence and courage. I was further informed that there had been a popular tumult among the pueblos, or civilized Indians, residing near Taos, against the "foreigners" of that place; in which they had plundered their houses and ill-treated their families. Among those whose property had been destroyed, was Mr. Beaubien, father-in-law of Maxwell, from whom I had expected to obtain supplies, and who had been obliged to make his escape to Santa Fé.
By this position of affairs, our expectation of obtaining supplies from Taos was cut off. I had here the satisfaction to meet our good buffalo- hunter of 1842, Christopher Carson, whose services I considered myself fortunate to secure again; and as a reinforcement of mules was absolutely necessary, I dispatched him immediately, with an account of our necessities, to Mr. Charles Bent, whose principal post is on the Arkansas river, about seventy-five miles below Fontaine-qui-bouit. He was directed to proceed from that post by the nearest route across the country, and meet me, with what animals he should be able to obtain, at St. Vrain's fort. I also admitted into the party Charles Towns, a native of St. Louis, a serviceable man, with many of the qualities of a good voyageur. According to our observations, the latitude of the mouth of the river is 38° 15' 23", its longitude 104° 58' 30", and its elevation above the sea 4,880 feet.
On the morning of the 16th, the time for Maxwell's arrival having expired, we resumed our journey, leaving for him a note, in which it was stated that I would wait for him at St. Vrain's fort, until the morning of the 26th, in the event that he should succeed in his commission. Our direction was up the Boiling Spring river, it being my intention to visit the celebrated springs from which the river takes its name, and which are on its upper waters, at the foot of Pike's peak. Our animals fared well while we were on this stream, there being everywhere a great abundance of prele. Ipomea leptophylla in bloom, was a characteristic plant along the river, generally in large bunches, with two to five flowers on each. Beautiful clusters of the plant resembling mirabilis jalapa were numerous, and glycyrrhiza lepidota was a characteristic of the bottoms. Currants nearly ripe were abundant, and among the shrubs which covered the bottom was a very luxuriant growth of chenopodiaceous shrubs, four to six feet high. On the afternoon of the 17th we entered among the broken ridges at the foot of the mountains, where the river made several forks. Leaving the camp to follow slowly, I rode ahead in the afternoon in search of the springs. In the meantime, the clouds, which had been gathered all the afternoon over the mountains, began to roll down their sides; and a storm so violent burst upon me, that it appeared I had entered the storehouse of the thunder-storms. I continued, however, to ride along up the river until about sunset, and was beginning to be doubtful of finding the springs before the next day, when I came suddenly upon a large smooth rock, about twenty yards in diameter, where the water from several springs was bubbling and boiling up in the midst of a white incrustation, with which it had covered a portion of the rock. As this did not correspond with the description given the by the hunters, I did not stop to taste the water, but dismounting, walked a little way up the river, and, passing through a narrow thicket of shrubbery bordering the stream, stepped directly upon a huge white rock, at the foot of which the river, already become a torrent, foamed along, broken by a small fall. A deer which had been drinking at the spring was startled by my approach, and, springing across the river, bounded off up the mountain. In the upper part of the rock, which had apparently been formed by deposition, was a beautiful white basin, overhung by currant bushes, in which the cold clear water bubbled up, kept in constant motion by the escaping gas, and overflowing the rock, which it had almost entirely covered with a smooth crust of glistening white. I had all day refrained from drinking, reserving myself for the spring; and as I could not well be more wet than the rain had already made me, I lay down by the side of the basin, and drank heartily of the delightful water. The spring is situated immediately at the foot of lofty mountains, beautifully timbered, which sweep closely round, shutting up the little valley in a kind of cove. As it was beginning to grow dark, I rode quickly down the river, on which I found the camp a few miles below.
The morning of the 18th was beautiful and clear; and, all the people being anxious to drink of these famous waters, we encamped immediately at the springs, and spent there a very pleasant day. On the opposite side of the river is another locality of springs, which are entirely of same nature. The water has a very agreeable taste, which Mr. Preuss found very much to resemble that of the famous Selter springs in the grand duchy of Nassau, a country famous for wine and mineral waters; and it is almost entirely of the same character, though still more agreeable than that of the famous Bear springs, near Bear river of the Great Salt lake. The following is an analysis of an incrustation with which the water had covered a piece of wood lying on the rock:
| Carbonate of lime, | 92.25 |
| Carbonate of magnesia, | 1.21 |
| Sulphate of lime, | .23 |
| Chloride of calcium, | |
| Chloride of magnesia, | |
| Silica, | 1.50 |
| Vegetable matter, | .20 |
| Moisture and loss, | 4.61 |
| 100.00 |
At eleven o'clock, when the temperature of the air was 73°, that of the water in this was 60.5°; and that of the upper spring, which issued from the flat rock, more exposed to the sun, was 69°. At sunset, when the temperature of the air was 66°, that of the lower springs was 58°, and that of the upper 61°.
19th.--A beautiful and clear morning, with a slight breeze from the northwest; the temperature of the air at sunrise being 57.5°. At this time the temperature of the lower spring was 57.8°, springs was 58°, and that of the upper 54.3°.
The trees in the neighborhood were birch, willow, pine, and an oak resembling quercus alba. In the shrubbery along the river are currant bushes, (ribes,) of which the fruit has a singular piny flavor; and on the mountain side, in a red gravelly soil, is a remarkable coniferous tree, (perhaps an abies,) having the leaves singularly long, broad and scattered, with bushes of spiraea ariaefolia. By our observations, this place is 6,350 feet above the sea, in latitude 38° 52' 10", and longitude 105° 22' 45".
Resuming our journey on this morning, we descended the river, in order to reach the mouth of the eastern fork, which I proposed to ascend. The left bank of the river here is very much broken. There is a handsome little bottom on the right, and both banks are exceedingly picturesque--strata of red rock, in nearly perpendicular walls, crossing the valley from north to south. About three miles below the springs, on the right bank of the river, is a nearly perpendicular limestone rock, presenting a uniformly unbroken surface, twenty to forty feet high, containing very great numbers of a large univalve shell; which appears to belong to the genus inoceramus.
In contact with this, to the westward, was another, stratum of limestone, containing fossil shells of a different character; and still higher up on the stream were parallel strata, consisting of a compact somewhat crystalline limestone, and argillaceous bituminous limestone in thin layers. During the morning, we traveled up the eastern fork of the Fontaine-qui-bouit river, our road being roughened by frequent deep gullies timbered with pine, and halted to noon on a small branch of the stream, timbered principally with the narrow-leaved cottonwood, (populus angustifolia,) called by the Canadians liard amere. On a hill near by, were two remarkable columns of a grayish-white conglomerate rock, one of which was about twenty feet high, and two feet in diameter. They are surmounted by slabs of a dark ferruginous conglomerate, forming black caps, and adding very much to their columnar effect at a distance. This rock is very destructible by the action of the weather, and the hill, of which they formerly constituted a part, is entirely abraded.
