6th.--The morning warm, the thermometer 46 at sunrise, and sky entirely clouded. After traveling about three miles over an extremely rocky road, the volcanic fragments began to disappear; and, entering among the hills at the point of the mountain, we found ourselves suddenly in a granite country. Here, the character of the vegetation was very much changed; the artemisia disappeared almost entirely, showing only at intervals towards the close of the day, and was replaced by Purshia tridentata, with flowering shrubs, and small fields of _dieteria divaricata,_ which gave bloom and gayety to the hills. These were everywhere covered with a fresh and green short gra.s.s, like that of the early spring. This is the fall or second growth, the dried gra.s.s having been burnt off by the Indians; and wherever the fire has pa.s.sed, the bright, green color is universal. The soil among the hills is altogether different from that of the river plain, being in many places black, in others sandy and gravelly, but of a firm and good character, appearing to result from the decomposition of the granite rocks, which is proceeding rapidly.

In quitting for a time the artemisia (sage) through which we had been so long voyaging, and the sombre appearance of which is so discouraging, I have to remark, that I have been informed that in Mexico wheat is grown upon the ground which produces this shrub; which, if true, relieves the soil from the character of sterility imputed to it. Be this as it may, there is no dispute about the gra.s.s, which is almost universal on the hills and mountains, and always nutritious, even in its dry state. We pa.s.sed on the way ma.s.ses of granite on the slope of the spur, which was very much weathered and abraded. This is a white feldspathic granite, with small scales of black mica; smoky quartz and garnets appear to const.i.tute this portion of the mountain.

The road at noon reached a broken ridge, on which were scattered many boulders or blocks of granite; and, pa.s.sing very small streams, where, with a little more than the usual timber, was sometimes gathered a little wilderness of plants, we encamped on a small stream, after a march of 22 miles, in company with a few Indians. Temperature at sunset 51; and the night was partially clear, with a few stars visible through drifting white clouds. The Indians made an unsuccessful attempt to steal a few horses from us--a thing of course with them, and to prevent which the traveler is on perpetual watch.

7th.--The day was bright, clear, pleasant, with a temperature of 45; and we breakfasted at sunrise, the birds singing in the trees as merrily as if we were in the midst of summer. On the upper edge of the hills on the opposite side of the creek, the black volcanic rock appears; and ascending these, the road pa.s.sed through a basin, around which the hills swept in such a manner as to give it the appearance of an old crater. Here were strata and broken beds of black scoriated rock, and hills composed of the same, on the summit of one of which there was an opening resembling a rent. We traveled to-day through a country resembling that of yesterday, where, although the surface was hilly, the road was good, being firm, and entirely free from rocks and artemisia. To our left, below, was the great sage plain; and on the right were the near mountains, which presented a smoothly-broken character, or rather a surface waved into numberless hills. The road was occasionally enlivened by meeting Indians, and the day was extremely beautiful and pleasant; and we were pleased to be free from the sage, even for a day. When we had traveled about eight miles, we were nearly opposite to the highest portion of the mountains on the left side of the Smoke River valley; and, continuing on a few miles beyond, we came suddenly in sight of the broad green line of the valley of the _Riviere Boisee_, (wooded river,) black near the gorge where it debouches into the plains, with high precipices of basalt, between walls of which it pa.s.ses, on emerging from the mountains. Following with the eye its upward course, it appears to be shut in among lofty mountains, confining its valley in a very rugged country.

Descending the hills, after traveling a few miles along the high plain, the road brought us down upon the bottoms of the river, which is a beautiful, rapid stream, with clear mountain water; and, as the name indicates, well wooded with some varieties of timber--among which are handsome cottonwoods. Such a stream had become quite a novelty in this country, and we were delighted this afternoon to make a pleasant camp under fine old trees again. There were several Indian encampments scattered along the river; and a number of their inhabitants, in the course of the evening, came to the camp on horseback with dried and fresh fish, to trade. The evening was clear, and the temperature at sunset 57.

At the time of the first occupation of this region by parties engaged in the fur-trade, a small party of men, under the command of ----- Reid, const.i.tuting all the garrison of a small fort on this river, were surprised and ma.s.sacred by the Indians; and to this event the stream owes its occasional name of _Reid's river_. On the 8th we traveled about 26 miles, the ridge on the right having scattered pines on the upper parts; and, continuing the next day our road along the river bottom, after a day's travel of 24 miles, we encamped in the evening on the right bank of the river, a mile above the mouth, and early the next morning arrived at Fort _Boise_. This is a simple dwelling-house on the right bank of Snake river, about a mile below the mouth of Riviere Boisee; and on our arrival we were received with an agreeable hospitality by Mr. Payette, an officer of the Hudson's Bay Company, in charge of the fort, all of whose garrison consisted in a Canadian _engage_.

Here the road recrosses the river, which is broad and deep; but, with our good boat, aided by two canoes, which were found at the place, the camp was very soon transferred to the left bank. Here we found ourselves again surrounded by the sage; artemisia tridentata, and the different shrubs which during our voyage had always made their appearance abundantly on saline soils, being here the prevailing and almost the only plants. Among them the surface was covered with the usual saline efflorescences, which here consist almost entirely of carbonate of soda, with a small portion of chloride of sodium. Mr. Payette had made but slight attempts at cultivation, his efforts being limited to raising a few vegetables, in which he succeeded tolerably well; the post being princ.i.p.ally supported by salmon. He was very hospitable and kind to us, and we made a sensible impression upon all his comestibles; but our princ.i.p.al inroad was into the dairy, which was abundantly supplied, stock appearing to thrive extremely well; and we had an unusual luxury in a present of fresh b.u.t.ter, which was, however, by no means equal to that of Fort Hall--probably from some accidental cause. During the day we remained here, there were considerable numbers of miserable, half-naked Indians around the fort, who had arrived from the neighboring mountains. During the summer, the only subsistence of these people is derived from the salmon, of which they are not provident enough to lay up a sufficient store for the winter, during which many of them die from absolute starvation.

Many little accounts and scattered histories, together with an acquaintance which I gradually acquired of their modes of life, had left the aboriginal inhabitants of this vast region pictured in my mind as a race of people whose great and constant occupation was the means of procuring a subsistence; and though want of s.p.a.ce and other reasons will prevent me from detailing the many incidents which made this familiar to me, this great feature among the characteristics of the country will gradually be forced upon your mind.

Pointing to the group of Indians who had just arrived from the mountains on the left side of the valley, and who were regarding our usual appliances of civilization with an air of bewildered curiosity, Mr.

Payette informed me that, every year since his arrival at this post, he had unsuccessfully endeavored to induce these people to lay up a store of salmon for their winter provision. While the summer weather and the salmon lasted, they lived contentedly and happily, scattered along the different streams where fish are to be found; and as soon as the winter snows began to, fall, little smokes would be seen rising among the mountains, where they would be found in miserable groups, starving out the winter; and sometimes, according to the general belief, reduced to the horror of cannibalism--the strong, of course, preying on the weak. Certain it is they are driven to any extremity for food, and eat every insect, and every creeping thing, however loathsome and repulsive. Snails, lizards, ants-- all are devoured with the readiness and greediness of mere animals.

In common with all the other Indians we had encountered since reaching the Pacific waters, these people use the Shoshonee or Snake language, which you will have occasion to remark, in the course of the narrative, is the universal language over a very extensive region.

On the evening of the 10th, I obtained, with the usual observations, a very excellent emersion of the first satellite, agreeing very nearly with the chronometer. From these observations, the longitude of the fort is 116 47' 00", lat.i.tude 43 49' 22", and elevation above the sea 2,100 feet.

Sitting by the fire on the river bank, and waiting for the immersion of the satellite, which did not take place until after midnight, we heard the monotonous song of the Indians, with which they accompany a certain game of which they are very fond. Of the poetry we could not judge, but the music was miserable.

11th.--The morning was clear, with a light breeze from the east, and a temperature at sunrise of 33. A part of a bullock purchased at the fort, together with the boat, to a.s.sist him in crossing, was left here for Mr.

Fitzpatrick, and at 11 o'clock we resumed our journey; and directly leaving the river, and crossing the artemisia plain, in several ascents we reached the foot of a ridge, where the road entered a dry sandy hollow, up which it continued to the head; and, crossing a dividing ridge, entered a similar one. We met here two poor emigrants, (Irishmen,) who had lost their horses two days since--probably stolen by the Indians; and were returning to the fort, in hopes to hear something of them there. They had recently had nothing to eat; and I halted to unpack an animal, and gave them meat for their dinner. In this hollow, the artemisia is partially displaced on the hill-sides by gra.s.s; and descending it -- miles, about sunset we reached the _Riviere aux Malheurs_, (the unfortunate or unlucky river,)--a considerable stream, with an average breadth of 50 feet, and, at this time, 18 inches' depth of water.

The bottom lands were generally one and a half mile broad, covered princ.i.p.ally with long dry gra.s.s; and we had difficulty to find sufficient good gra.s.s for the camp. With the exception of a bad place of a few hundred yards long, which occurred in rounding a point of hill to reach the ford of the river, the road during the day had been very good.

12th.--The morning was clear and calm, and the thermometer at sunrise 23.

My attention was attracted by a smoke on the right side of the river, a little below the ford, where I found, on the low banks near the water, a considerable number of hot springs, in which the temperature of the water was 193. The ground, which was too hot for the naked foot, was covered above and below the springs with an incrustation of common salt, very white and good, and fine-grained.

Leading for five miles up a broad dry branch of the Malheurs river, the road entered a sandy hollow, where the surface was rendered firm by the admixture of other rock; being good and level until arriving near the head of the ravine, where it became a little rocky, and we met with a number of sharp ascents over an undulating surface. Crossing here a dividing ridge, it becomes an excellent road of gradual descent down a very marked hollow; in which, after ten miles, willows began to appear in the dry bed of a head of the _Riviere aux Bouleaux_, (Birch river;) and descending seven miles, we found, at its junction with another branch, a little water, not very good or abundant, but sufficient, in case of necessity, for a camp. Crossing Birch river, we continued for about four miles across a point of hill; the country on the left being entirely mountainous, with no level spot to be seen; whence we descended to Snake river--here a fine- looking stream, with a large body of water and a smooth current; although we hear the roar, and see below us the commencement of rapids, where it enters among the hills. It forms here a deep bay, with a low sand island in the midst; and its course among the mountains is agreeably exchanged for the black volcanic rock. The weather during the day had been very bright and extremely hot; but, as usual, so soon as the sun went down, it was necessary to put on overcoats.

I obtained this evening an observation of an emersion of the first satellite, and our observations of the evening place this encampment in lat.i.tude 44 17' 36", and longitude 116 56' 45", which is the mean of the results from the satellite and chronometer. The elevation above the sea is 1,880 feet. At this encampment, the gra.s.s is scanty and poor.

13th.--The morning was bright, with the temperature at sunrise 28. The horses had strayed off during the night, probably in search of gra.s.s; and, after a considerable delay, we had succeeded in finding all but two, when, about nine o'clock, we heard the sound of an Indian song and drum approaching; and shortly after, three Cayuse Indians appeared in sight, bringing with them the two animals. They belonged to a party which had been on a buffalo-hunt in the neighborhood of the Rocky mountains, and were hurrying home in advance. We presented them with some tobacco and other things, with which they appeared well satisfied, and, moderating their pace, traveled in company with us.

We were now about to leave the valley of the great southern branch of the Columbia river, to which the absence of timber, and the scarcity of water, give the appearance of a desert, to enter a mountainous region, where the soil is good, and in which the face of the country is covered with nutritious gra.s.ses and dense forest--land embracing many varieties of trees peculiar to the country, and on which the timber exhibits a luxuriance of growth unknown to the eastern part of the continent and to Europe. This mountainous region connects itself in the southward and westward with the elevated country belonging to the Cascade or California range; and, as will be remarked in the course of the narrative, forms the eastern limit of the fertile and timbered lands along the desert and mountainous region included within the Great Basin--a term which I apply to the intermediate region between the Rocky mountains and the next range, containing many lakes, with their own system of rivers and creeks, (of which the Great Salt is the princ.i.p.al,) and which have no connection with the ocean, or the great rivers which flow into it. This Great Basin is yet to be adequately explored. And here, on quitting the banks of a sterile river, to enter on arable mountains, the remark may be made, that, on this western slope of our continent, the usual order or distribution of good and bad soil is often reversed; the river and creek bottoms being often sterile, and darkened with the gloomy and barren artemisia; while the mountain is often fertile, and covered with rich gra.s.s, pleasant to the eye, and good for flocks and herds.

Leaving entirely the Snake river, which is said henceforth to pursue its way through canons, amidst rocky and impracticable mountains, where there is no possibility of traveling with animals, we ascended a long and steep hill; and crossing the dividing ridge, came down into the valley of _Burnt_ river, which here looks like a hole among the hills. The average breadth of the stream here is thirty feet; it is well fringed with the usual small timber; and the soil in the bottoms is good, with better gra.s.s than we had lately been accustomed to see.

We now traveled through a very mountainous country; the stream running rather in a ravine than a valley, and the road is decidedly bad and dangerous for single wagons, frequently crossing the stream where the water is sometimes deep; and all the day the animals were fatigued in climbing up and descending a succession of steep ascents, to avoid the precipitous hill-sides; and the common trail, which leads along the mountain-side at places where the river strikes the base, is sometimes bad even for a horseman. The mountains along this day's journey were composed, near the river, of a slaty calcareous rock in a metamorphic condition. It appears originally to have been a slaty sedimentary limestone, but its present condition indicates that it has been altered, and has become partially crystalline--probably from the proximity of volcanic rocks. But though traveling was slow and fatiguing to the animals, we were delighted with the appearance of the country, which was green and refreshing after our tedious journey down the parched valley of Snake river. The mountains were covered with good bunch-gra.s.s, (_festuca_;) the water of the streams was cold and pure; their bottoms were handsomely wooded with various kinds of trees; and huge and lofty picturesque precipices where the river cut through the mountain.

We found in the evening some good gra.s.s and rushes; and encamped among large timber, princ.i.p.ally birch, which had been recently burnt, and blackened, and almost destroyed by fire. The night was calm and tolerably clear, with the thermometer at sunset at 59. Our journey to-day was about twenty miles.

14th.--The day was clear and calm, with a temperature at sunrise of 46.

After traveling about three miles up the valley, we found the river shut up by precipices in a kind of canon, and the road makes a circuit over the mountains. In the afternoon we reached the river again, by another little ravine; and, after traveling along it for a few miles, left it enclosed among rude mountains; and, ascending a smaller branch; encamped on it about five o'clock, very much elevated above the valley. The view was everywhere limited by mountains, on which were no longer seen the black and barren rocks, but a fertile soil, with excellent gra.s.s, and partly well covered with pine. I have never seen a wagon-road equally bad in the same s.p.a.ce, as this of yesterday and to-day. I noticed where one wagon had been overturned twice, in a very short distance; and it was surprising to me that those wagons which were in the rear, and could not have had much a.s.sistance, got through at all. Still, there is no mud; and the road has one advantage, in being perfectly firm. The day had been warm and very pleasant, and the night was perfectly clear.

15th.--The thermometer at daylight was 42, and at sunrise 40; clouds, which were scattered over all the sky, disappeared with the rising sun.

The trail did not much improve until we had crossed the dividing-ground between the _Brulee_ (Burnt) and Powder rivers. The rock displayed on the mountains, as we approached the summit, was a compact trap, decomposed on the exposed surfaces, and apparently an altered argillaceous sandstone, containing small crystalline nodules of anolcime, apparently filling cavities originally existing. From the summit here, the whole horizon shows high mountains; no high plain or level is to be seen; and on the left, from south around by the west to north, the mountains are black with pines; while, through the remaining s.p.a.ce to the eastward, they are bald, with the exception of some scattered pines. You will remark that we are now entering a region where all the elevated parts are covered with dense and heavy forests. From the dividing grounds we descended by a mountain road to Powder river, on an old bed of which we encamped. Descending from the summit, we enjoyed a picturesque view of high rocky mountains on the right, illuminated by the setting sun.

From the heights we had looked in vain for a well known landmark on Powder river, which had been described to me by Mr. Payette as _l'arbre seul_, (the lone tree;) and, on arriving at the river, we found a fine tall pine stretched on the ground, which had been felled by some inconsiderate emigrant axe. It had been a beacon on the road for many years past. Our Cayuses had become impatient to reach their homes, and traveled on ahead to day; and this afternoon we were visited by several Indians who belonged to the tribes on the Columbia. They were on horseback, and were out on a hunting excursion, but had obtained no better game than a large gray hare, of which each had some six or seven hanging to his saddle. We were also visited by an Indian who had his lodge and family in the mountain to the left. He was in want of ammunition, and brought with him a beaver-skin to exchange, and which he valued at six charges of powder and ball. I learned from him that there are very few of these animals remaining in this part of the country.

The temperature at sunset was 61, and the evening clear. I obtained, with other observations, an immersion and emersion of the third satellite.

Elevation 3,100 feet.

16th.--For several weeks the weather in the daytime has been very beautiful, clear, and warm; but the nights, in comparison, are very cold.

During the night there was ice a quarter of an inch thick in the lodge; and at daylight the thermometer was at 16, and the same at sunrise, the weather being calm and clear. The annual vegetation now is nearly gone, almost all the plants being out of bloom.

Last night two of our horses had run off again, which delayed us until noon, and we made to-day but a short journey of 13 miles, the road being very good, and encamped in a fine bottom of Powder river.

The thermometer at sunset was at 61, with an easterly wind, and partially clear sky; and the day has been quite pleasant and warm, though more cloudy than yesterday; and the sun was frequently faint, but it grew finer and clearer towards evening.

17th.--Thermometer at sunrise 25. The weather at daylight was fine, and the sky without a cloud; but these came up, or were formed by the sun, and at seven were thick over all the sky. Just now, this appears to be the regular course--clear and brilliant during the night, and cloudy during the day. There is snow yet visible in the neighboring mountains, which yesterday extended along our route to the left, in a lofty and dark-blue range, having much the appearance of the Wind River mountains. It is probable that they have received their name of the _Blue mountains_ from the dark-blue appearance given to them by the pines. We traveled this morning across the affluents to Powder river, the road being good, firm, and level, and the country became constantly more pleasant and interesting. The soil appeared to be very deep, and is black and extremely good, as well among the hollows of the hills on the elevated plats, as on the river bottoms, the vegetation being such as is usually found in good ground. The following a.n.a.lytical result shows the precise qualities of this soil, and will justify to science the character of fertility which the eye attributes to it:

From the waters of this stream, the road ascended by a good and moderate ascent to a dividing ridge, but immediately entered upon ground covered with fragments of an altered silicious slate, which are in many places large, and render the road racking to a carriage. In this rock the planes of deposition are distinctly preserved, and the metamorphism is evidently due to the proximity of volcanic rocks. On either side, the mountains here are densely covered with tall and handsome trees; and, mingled with the green of a variety of pines, is the yellow of the European larch, (_pinus larix_,) which loses its leaves in the fall. From its present color, we were enabled to see that it forms a large proportion of the forests on the mountains, and is here a magnificent tree, attaining sometimes the height of 200 feet, which I believe is elsewhere unknown.

About two in the afternoon we reached a high point of the dividing ridge, from which we obtained a good view of the _Grand Rond_--a beautiful level basin, or mountain valley, covered with good gra.s.s, on a rich soil, abundantly watered, and surrounded by high and well-timbered mountains-- and its name descriptive of its form--the great circle. It is a place--one of the few we have seen on our journey so far--where a farmer would delight to establish himself, if he were content to live in the seclusion which it imposes. It is about 20 miles in diameter, and may, in time, form a superb county. Probably with the view of avoiding a circuit, the wagons had directly descended into the _Rond_ by the face of a hill so very rocky and continuously steep as to be apparently impracticable, and, following down on their trail, we encamped on one of the branches of the Grand Rond river, immediately at the foot of the hill. I had remarked, in descending, some very white spots glistening on the plain, and, going out in that direction after we had encamped, I found them to be the bed of a dry salt lake, or marsh, very firm and bare, which was covered thickly with a fine white powder, containing a large quant.i.ty of carbonate of soda, (thirty-three in one hundred parts.)

The old gra.s.s had been lately burnt off from the surrounding hills, and, wherever the fire had pa.s.sed, there was a recent growth of strong, green, and vigorous gra.s.s; and the soil of the level prairie, which sweeps directly up to the foot of the surrounding mountains, appears to be very rich, producing flax spontaneously and luxuriantly in various places.

The elevation of this encampment is 2,940 feet above the sea.

18th.--It began to rain an hour before sunrise, and continued until ten o'clock; the sky entirely overcast, and the temperature at sunrise 48.

We resumed our journey somewhat later than usual, travelling in a nearly north direction across the beautiful valley; and about noon reached a place on one of the princ.i.p.al streams, where I had determined to leave the emigrant trail, in the expectation of finding a more direct and better road across the Blue mountains. At this place the emigrants appeared to have held some consultation as to their further route, and finally turned directly off to the left; reaching the foot of the mountain in about three miles, which they ascended by a hill as steep and difficult as that by which we had yesterday descended to the Rond. Quitting, therefore, this road, which, after a very rough crossing, issues from the mountains by the heads of the _Umatilah_ river, we continued our northern course across the valley, following an Indian trail which had been indicated to me by Mr. Payette, and encamped at the northern extremity of the Grand Rond, on a slough-like stream of very deep water, without any apparent current. There are some pines here on the low hills at the creek; and in the northwest corner of the Rond is a very heavy body of timber, which descends into the plain. The clouds, which had rested very low along the mountain sides during the day, rose gradually up in the afternoon; and in the evening the sky was almost entirely clear, with a temperature at sunset of 47. Some indifferent observations placed the camp in longitude 117 28' 26", lat.i.tude 45 26' 47"; and the elevation was 2,600 feet above the sea.

19th.--This morning the mountains were hidden by fog; there was a heavy dew during the night, in which the exposed thermometer at daylight stood at 32, and at sunrise the temperature was 35.

We pa.s.sed out of the Grand Rond by a fine road along the creek, which, for a short distance, runs in a kind of rocky chasm. Crossing a low point, which was a little rocky, the trail conducted into the open valley of the stream--a handsome place for farms; the soil, even of the hills, being rich and black. Pa.s.sing through a point of pines, which bore evidences of being very much frequented by the Indians, and in which the trees were sometimes apparently 200 feet high, and three to seven feet in diameter, we halted for a few minutes in the afternoon at the foot of the Blue mountains, on a branch of the Grand Rond river, at an elevation of 2,700 feet. Resuming our journey, we commenced the ascent of the mountains through an open pine forest of large and stately trees, among which the balsam pine made its appearance; the road being good, with the exception of one steep ascent, with a corresponding descent, which might both have been easily avoided by opening the way for a short distance through the timber. It would have been well had we encamped on the stream where we had halted below, as the night overtook us on the mountain, and we were obliged to encamp without water, and tie up the animals to the trees for the night. We halted on a smooth open place of a narrow ridge, which descended very rapidly to a ravine or piny hollow, at a considerable distance below; and it was quite a pretty spot, had there been water near.

But the fires at night look very cheerless after a day's march, when there is no preparation for supper going on; and, after sitting some time around the blazing logs, Mr. Preuss and Carson, with several others, volunteered to take the India-rubber buckets and go down into the ravine in search of water. It was a very difficult way in the darkness down the slippery side of the steep mountain, and harder still to climb about half a mile up again; but they found the water, and the cup of coffee (which it enabled us to make) and bread were only enjoyed with greater pleasure.

At sunset the temperature was 46; the evening remarkably clear; and I obtained an emersion of the first satellite, which does not give a good result, although the observation was a very good one. The chronometric longitude was 117 28' 34", lat.i.tude 45 38' 07", and we had ascended to an elevation of 3,830 feet. It appeared to have snowed yesterday on the mountains, their summits showing very white to-day.

20th.--There was a heavy white frost during the night, and at sunrise the temperature was 37.

The animals had eaten nothing during the night; and we made an early start, continuing our route among the pines, which were more dense than yesterday, and still retained their magnificent size. The larches cl.u.s.ter together in ma.s.ses on the side of the mountains, and their yellow foliage contrasts handsomely with the green of the balsam and other pines. After a few miles we ceased to see any pines, and the timber consisted of several varieties of spruce, larch, and balsam pine, which have a regularly conical figure. These trees appeared from 60 to nearly 200 feet in height; the usual circ.u.mference being 10 to 12 feet, and in the pines sometimes 21 feet. In open places near the summit, these trees became less high and more branching, the conical form having a greater base. The instrument carriage occasioned much delay, it being frequently necessary to fell trees and remove the fallen timber. The trail we were following led up a long spur, with a very gradual and gentle rise. At the end of three miles, we halted at an open place near the summit, from which we enjoyed a fine view over the mountainous country where we had lately traveled, to take a barometrical observation at the height of 4,460 feet.

After traveling occasionally through open places in the forest, we were obliged to cut a way through a dense body of timber, from which we emerged on an open mountain-side, where we found a number of small springs, and encamped after a day's journey of ten miles. Our elevation here was 5,000 feet.
