JULY.

Traveling along up the valley of the river, here 4,000 feet above the sea, in the afternoon of July 1, we caught a far and uncertain view of a faint blue ma.s.s in the west, as the sun sank behind it; and from our camp in the morning, at the mouth of Bijou, Long's peak and the neighboring mountains stood out into the sky, grand and luminously white, covered to their bases with glittering snow.

On the evening of the 3d, as we were journeying along the partially overflowed bottoms of the Platte, where our pa.s.sage stirred up swarms of musquitoes, we came unexpectedly on an Indian, who was perched upon a bluff, curiously watching the movements of our caravan. He belonged to a village of Oglallah Sioux, who had lost all their animals in the severity of the preceding winter, and were now on their way up the Bijou fork to beg horses from the Arapahoes, who were hunting buffalo at the head of that river. Several came into our camp at noon; and, as they were hungry, as usual, they were provided with buffalo-meat, of which the hunters had brought in an abundant supply.

About noon, on the 4th of July, we arrived at the fort, where Mr. St.

Vrain received us with his customary kindness, and invited us to join him in a feast which had been prepared in honor of the day.

Our animals were very much worn out, and our stock of provisions entirely exhausted, when we arrived at the fort; but I was disappointed in my hope of obtaining relief, as I found it in a very impoverished condition; and we were able to procure only a little unbolted Mexican flour, and some salt, with a few pounds of powder and lead.

As regarded provisions, it did not much matter in a country where rarely the day pa.s.sed without seeing some kind of game, and where it was frequently abundant. It was a rare thing to lie down hungry, and we had already learned to think bread a luxury; but we could not proceed without animals, and our own were not capable of prosecuting the journey beyond the mountains without relief.

I had been informed that a large number of mules had recently arrived at Taos, from Upper California; and as our friend, Mr. Maxwell, was about to continue his journey to that place, where a portion of his family resided, I engaged him to purchase for me ten or twelve mules, with the understanding that he should pack them with provisions and other necessaries, and meet me at the mouth of the _Fontaine-qui-bouit_, on the Arkansas river, to which point I would be led in the course of the survey.

Agreeably to his own request, and in the conviction that his habits of life and education had not qualified him to endure the hard life of a voyageur, I discharged here one of my party, Mr. Oscar Sarpy, having furnished him with arms and means of transportation to Fort Laramie, where he would be in the line of caravans returning to the States.

At daybreak, on the 6th of July, Maxwell was on his way to Taos; and a few hours after we also had recommenced our journey up the Platte, which was continuously timbered with cottonwood and willow, on a generally sandy soil. Pa.s.sing on the way the remains of two abandoned forts, (one of which, however, was still in good condition,) we reached, in ten miles, Fort Lancaster, the trading establishment of Mr. Lupton.

His post was beginning to a.s.sume the appearance of a comfortable farm: stock, hogs, and cattle, were ranging about on the prairie--there were different kinds of poultry; and there was a wreck of a promising garden, in which a considerable variety of vegetables had been in a flourishing condition; but it had been almost entirely ruined by the recent high waters. I remained to spend with him an agreeable hour, and set off in a cold storm of rain, which was accompanied with violent thunder and lightning. We encamped immediately on the river, sixteen miles from St.

Vrain's. Several Arapahoes, on their way to the village which was encamped a few miles above us, pa.s.sed by the camp in the course of the afternoon.

Night set in stormy and cold, with heavy and continuous rain, which lasted until morning.

7th.--We made this morning an early start, continuing to travel up the Platte; and in a few miles frequent bands of horses and mules, scattered for several miles round about, indicated our approach to the Arapaho village, which we found encamped in a beautiful bottom, and consisting of about one hundred and sixty lodges. It appeared extremely populous, with a great number of children--a circ.u.mstance which indicated a regular supply of the means of subsistence. The chiefs, who were gathered together at the farther end of the village, received us (as probably strangers are always received to whom they desire to show respect or regard) by throwing their arms around our necks and embracing us.

It required some skill in horsemanship to keep the saddle during the performance of this ceremony, as our American horses exhibited for them the same fear they have for a bear, or any other wild animal. Having very few goods with me, I was only able to make them a meager present, accounting for the poverty of the gift by explaining that my goods had been left with the wagons in charge of Mr. Fitzpatrick, who was well known to them as the White Head, or the Broken Hand. I saw here, as I had remarked in an Arapaho village the preceding year, near the lodges of the chiefs; tall tripods of white poles supporting their spears and shields, which showed it to be a regular custom.

Though disappointed in obtaining the presents which had been evidently expected, they behaved very courteously; and, after a little conversation, I left them, and, continuing on up the river, halted to noon on the bluff, as the bottoms are almost inundated; continuing in the afternoon our route along the mountains, which were dark, misty, and shrouded--threatening a storm; the snow peaks sometimes glittering through the clouds beyond the first ridge.

We surprised a grizzly bear sauntering along the river, which, raising himself upon his hind legs, took a deliberate survey of us, that did not appear very satisfactory to him, and he scrambled into the river and swam to the opposite side. We halted for the night a little above Cherry creek; the evening cloudy, with many musquitoes. Some indifferent observations placed the camp in lat. 39 43' 53", and chronometric long. 105 24' 34".

8th.--We continued to-day to travel up the Platte: the morning pleasant, with a prospect of fairer weather. During the forenoon our way lay over a more broken country, with a gravelly and sandy surface; although the immediate bottom of the river was a good soil, of a dark and sandy mould, resting upon a stratum of large pebbles, or rolled stones, as at Laramie fork. On our right, and apparently very near, but probably 8 or 10 miles distant, and two or three thousand feet above us, ran the first range of the mountains, like a dark corniced line, in clear contrast with the great snowy chain which, immediately beyond, rose glittering five thousand feet above them. We caught this morning a view of Pike's peak; but it appeared for a moment only, as clouds rose early over the mountains, and shrouded them in mist and rain all the day. In the first range were visible, as at the Red b.u.t.tes on the North fork, very lofty escarpments of red rock.

While traveling through this region, I remarked that always in the morning the lofty peaks were visible and bright, but very soon small white clouds began to settle around them--brewing thicker and thicker as the day advanced, until the afternoon, when the thunder began to roll; and invariably at evening we had more or less of a thunder storm. At 11 o'clock, and 21 miles from St. Vrain's fort, we reached a point in this southern fork of the Platte, where the stream is divided into three forks; two of these (one of them being much the largest) issuing directly from the mountains on the west, and forming, with the eastern-most branch, a river of the plains. The elevation of this point is about 5,500 feet above the sea; this river falling 2,800 feet in a distance of 316 miles, to its junction with the North fork of the Platte. In this estimate, the elevation of the junction is a.s.sumed as given by our barometrical observations in 1842. On the easternmost branch, up which we took our way, we first came among the pines growing on the top of a very high bank, and where we halted on it to noon; quaking asp (_populus tremuloides_) was mixed with the cottonwood, and there were excellent gra.s.s and rushes for the animals.

During the morning there occurred many beautiful flowers, which we had not hitherto met. Among them, the common blue flowering flax made its first appearance; and a tall and handsome species of _gilia_, with slender scarlet flowers, which appeared yesterday for the first time, was very frequent to-day.

We had found very little game since leaving the fort, and provisions began to get unpleasantly scant, as we had had no meat for several days; but towards sundown, when we had already made up our minds to sleep another night without supper, Lajeunesse had the good fortune to kill a fine deer, which he found feeding in a hollow near by; and as the rain began to fall, threatening an unpleasant night, we hurried to secure a comfortable camp in the timber.

To-night the camp fires, girdled with _appolas_ of fine venison, looked cheerful in spite of the stormy weather.

9th.--On account of the low state of our provisions and the scarcity of game, I determined to vary our route, and proceed several camps to the eastward, in the hope of falling in with the buffalo. This route along the dividing grounds between the South fork of the Platte and the Arkansas, would also afford some additional geographical information. This morning, therefore, we turned to the eastward, along the upper waters of the stream on which we had encamped, entering a country of picturesque and varied scenery; broken into rocky hills of singular shapes; little valleys, with pure crystal water, here leaping swiftly along, and there losing itself in the sands; green spots of luxuriant gra.s.s, flowers of all colors, and timber of different kinds--every thing to give it a varied beauty, except game. To one of these remarkably shaped hills, having on the summit a circular flat rock two or three hundred yards in circ.u.mference, some one gave the name of Poundcake, which it has been permitted to retain, as our hungry people seemed to think it a very agreeable comparison. In the afternoon a buffalo bull was killed, and we encamped on a small stream, near the road which runs from St. Vrain's fort to the Arkansas.

10th:--Snow fell heavily on the mountains during the night, and Pike's peak this morning is luminous and grand, covered from the summit, as low down as we can see, with glittering white. Leaving the encampment at 6 o'clock, we continued our easterly course over a rolling country, near to the high ridges, which are generally rough and rocky, with a coa.r.s.e conglomerate displayed in ma.s.ses, and covered with pines. The rock is very friable, and it is undoubtedly from its decomposition that the prairies derive their sandy and gravelly formation. In six miles we crossed a head- water of the Kioway river, on which we found a strong fort and _coral_ that had been built in the spring, and halted to noon on the princ.i.p.al branch of the river. During the morning our route led over a dark and vegetable mould, mixed with sand and gravel, the characteristic plant being _esparcette_, (_on.o.brychis sativa_,) a species of clover which is much used in certain parts of Germany for pasturage of stock--princ.i.p.ally hogs. It is sown on rocky waste ground, which would otherwise be useless, and grows very luxuriantly, requiring only a renewal of the seed about once in fifteen years. Its abundance here greatly adds to the pastoral value of this region. A species of antennaria in flower was very common along the line of road, and the creeks were timbered with willow and pine. We encamped on Bijou's fork, the water of which, unlike the clear streams we had previously crossed, is of a whitish color, and the soil of the bottom a very hard, tough clay. There was a prairie dog village on the bottom, and, in the endeavor to unearth one of the little animals, we labored ineffectually in the tough clay until dark. After descending, with a slight inclination, until it had gone the depth of two feet, the hole suddenly turned at a sharp angle in another direction for one more foot in depth, when it again turned, taking an ascending direction to the next nearest hole. I have no doubt that all their little habitations communicate with each other. The greater part of the people were sick to-day, and I was inclined to attribute their indisposition to the meat of the bull which had been killed the previous day.

11th.--There were no indications of buffalo having been recently in the neighborhood; and, unwilling to travel farther eastward, I turned this morning to the southward, up the valley of Bijou. _Esparcette_ occurred universally, and among the plants on the river I noticed, for the first time during this journey, a few small bushes of the _absinthe_ of the voyageurs, which is commonly used for firewood, (_artemesia tridentata_.) Yesterday and to-day the road has been ornamented with the showy bloom of a beautiful lupinus, a characteristic in many parts of the mountain region, on which were generally great numbers of an insect with very bright colors, (_litta vesicatoria_.)

As we were riding quietly along, eagerly searching every hollow in search of game, we discovered, at a little distance in the prairie, a large grizzly bear, so busily engaged in digging roots that he did not perceive us until we were galloping down a little hill fifty yards from him, when he charged upon us with such sudden energy that several of us came near losing our saddles. Being wounded, he commenced retreating to a rocky piny ridge near by, from which we were not able to cut him off, and we entered the timber with him. The way was very much blocked up with fallen timber; and we kept up a running fight for some time, animated by the bear charging among the horses. He did not fall until after he had received six rifle b.a.l.l.s. He was miserably poor, and added nothing to our stock of provisions.

We followed the stream to its head in a broken ridge, which, according to the barometer, was about 7,500 feet above the sea. This is a piny elevation, into which the prairies are gathered, and from which the waters flow, in almost every direction, to the Arkansas, Platte, and Kansas rivers; the latter stream having here its remotest sources. Although somewhat rocky and broken, and covered with pines, in comparison with the neighboring mountains, it scarcely forms an interruption to the great prairie plains which sweep up to their bases.

We had an excellent view of Pike's peak from this camp, at the distance of forty miles. This mountain barrier presents itself to travelers on the plains, which sweep almost directly to its bases--an immense and comparatively smooth and gra.s.sy prairie, in very strong contrast with the black ma.s.ses of timber, and the glittering snow above them. With occasional exceptions, comparatively so very small as not to require mention, these prairies are everywhere covered with a close and vigorous growth of a great variety of gra.s.ses, among which the most abundant is the buffalo gra.s.s, (_sesleria dactyloides_.) Between the Platte and Arkansas rivers, that part of this region which forms the basin drained by the waters of the Kansas, with which our operations made us more particularly acquainted, is based upon a formation of calcareous rocks.

The soil of all this country is excellent, admirably adapted to agricultural purposes, and would support a large agricultural and pastoral population. A glance at the map, along our several lines of travel, will show you that this plain is watered by many streams. Throughout the western half of the plain, these are shallow, with sandy beds, becoming deeper as they reach the richer lands approaching the Missouri river; they generally have bottom lands, bordered by bluffs varying from fifty to five hundred feet in height. In all this region the timber is entirely confined to the streams. In the eastern half, where the soil is a deep, rich, vegetable mould, retentive of rain and moisture, it is of vigorous growth, and of many different kinds; and throughout the western half it consists entirely of various species of cottonwood, which deserves to be called the tree of the desert--growing in sandy soils, where no other tree will grow --pointing out the existence of water, and furnishing to the traveler fuel, and food for his animals. Add to this that the western border of the plain is occupied by the Sioux, Arapaho, and Cheyenne nations, with the p.a.w.nees and other half-civilized tribes in its eastern limits, for whom the intermediate country is a war-ground, and you will have a tolerably correct idea of the appearance and condition of the country. Descending a somewhat precipitous and rocky hillside among the pines, which rarely appear elsewhere than on the ridge, we encamped at its foot, where there were several springs, which you will find laid down upon the map as one of the extreme sources of the Smoky Hill fork of the Kansas. From this place the view extended over the Arkansas valley, and the Spanish peaks in the south beyond. As the greater part of the men continued sick, I encamped here for the day, and ascertained conclusively, from experiments on myself, that their illness was caused by the meat of the buffalo bull.

On the summit of the ridge, near the camp, were several rock-built forts, which in front were very difficult of approach, and in the rear were protected by a precipice entirely beyond the reach of a rifle-ball. The evening was tolerably clear, with a temperature at sunset of 63.

Elevation of the camp seven thousand and three hundred feet.

Turning the next day to the southwest, we reached, in the course of the morning, the wagon-road to the settlements on the Arkansas river, and encamped in the afternoon on the _Fontaine-qui-bouit_ (or Boiling Spring) river, where it was fifty feet wide, with a swift current. I afterwards found that the spring and river owe their names to the bubbling of the effervescing gas in the former, and not to the temperature of the water, which is cold. During the morning a tall species of _gilia_, with a slender white flower, was characteristic; and, in the latter part of the day, another variety of _esparcette_, (wild clover,) having the flower white, was equally so. We had a fine sunset of golden brown; and in the evening, a very bright moon, with the near mountains, made a beautiful scene. Thermometer, at sunset, was 69, and our elevation above the sea 5,800 feet.

13th.--The morning was clear, with a northwesterly breeze, and the thermometer at sunrise at 46. There were no clouds along the mountains, and the morning sun showed very clearly their rugged character.

We resumed our journey very early down the river, following an extremely good lodge-trail, which issues by the head of this stream from the bayou Salade, a high mountain valley behind Pike's peak. The soil along the road was sandy and gravelly, and the river well timbered. We halted to noon under the shade of some fine large cottonwoods, our animals luxuriating on rushes, (_equisetum hyemale_,) which, along this river, were remarkably abundant. A variety of cactus made its appearance, and among several strange plants were numerous and beautiful cl.u.s.ters of a plant resembling _mirabilis jalapa_, with a handsome convolvulus I had not hitherto seen, (_calystegia_.) In the afternoon we pa.s.sed near the encampment of a hunter named Maurice, who had been out into the plains in pursuit of buffalo calves, a number of which I saw among some domestic cattle near his lodge. Shortly afterwards, a party of mountaineers galloped up to us--fine-looking and hardy men, dressed in skins, and mounted on good fat horses; among them were several Connecticut men, a portion of Wyeth's party, whom I had seen the year before, and others were men from the western states.

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 princ.i.p.ally 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 Fe.

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 princ.i.p.al 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 lat.i.tude 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 cl.u.s.ters 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, pa.s.sing 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 Na.s.sau, 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 a.n.a.lysis 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,------} Chloride of calcium, }----- .23 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 lat.i.tude 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 sh.e.l.l; which appears to belong to the genus _inoceramus_.

In contact with this, to the westward, was another, stratum of limestone, containing fossil sh.e.l.ls 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 princ.i.p.ally 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 const.i.tuted a part, is entirely abraded.

A shaft of the gun-carriage was broken in the afternoon; and we made an early halt, the stream being from twelve to twenty feet wide, with clear water. As usual, the clouds had gathered to a storm over the mountains, and we had a showery evening. At sunset, the thermometer stood at 62, and our elevation above the sea was. 6,530 feet.

20th.--This morning (as we generally found the mornings under these mountains) was very clear and beautiful, and the air cool and pleasant, with the thermometer at 44. We continued our march up the stream, along a green sloping bottom; between pine hills on the one hand; and the main Black hills on the other; towards the ridge which separates the waters of the Platte from those of the Arkansas. As we approached the diving ridge, the whole valley was radiant with flowers; blue, yellow, pink, white, scarlet; and purple, vie with each other in splendor. Esparcette was one of the highly characteristic plants, and a bright-looking flower (_gaillardia aristata_) was very frequent; but the most abundant plant along our road today, was _geranium maculatum_, which is the characteristic plant on this portion of the diving grounds. Crossing to the waters of the Platte, fields of blue flax added to the magnificence of this mountain garden; this was occasionally four feet in height, which was a luxuriance of growth that I rarely saw this almost universal plant attain throughout the journey. Continuing down a branch of the Platte, among high and very steep timbered hills, covered with fragments of sock, towards evening we issued from the piny region, and made a late encampment near Poundcake rock, on that fork of the river which we had ascended on the 8th of July. Our animals enjoyed the abundant rushes this evening, as the flies were so bad among the pines that they had been much hara.s.sed. A deer was killed here this evening; and again the evening was overcast, and a collection of brilliant red clouds in the west was followed by the customary squall of rain.

_Achillea millefolium_ (milfoil) was among the characteristic plants of the river bottoms to-day. This was one of the most common plants during the whole of our journey, occurring in almost every variety of situation.

I noticed it on the lowlands of the rivers, near the coast of the Pacific, and near to the snow among the mountains of the _Sierra Nevada_.

During this excursion, we had surveyed to its head one of the two princ.i.p.al branches of the upper Arkansas, 75 miles in length, and entirely completed our survey of the South fork of the Platte, to the extreme sources of that portion of the river which belongs to the plains, and heads in the broken hills of the Arkansas dividing ridge, at the foot of the mountains. That portion of its waters which were collected among these mountains, it was hoped to explore on our homeward voyage.

Reaching St. Vrain's fort on the morning of the 23d, we found Mr.

Fitzpatrick and his party in good order and excellent health, and my true and reliable friend, Kit Carson, who had brought with him ten good mules, with the necessary pack-saddles. Mr. Fitzpatrick, who had often endured every extremity of want during the course of his mountain life, and knew well the value of provisions in this country, had watched over our stock with jealous vigilance, and there was an abundance of flour, rice, sugar, and coffee, in the camp; and again we fared luxuriously. Meat was, however, very scarce; and two very small pigs, which we obtained at the fort, did not go far among forty men. Mr. Fitzpatrick had been here a week, during which time his men had been occupied in refitting the camp; and the repose had been very beneficial to his animals, which were now in tolerably good condition.
