Wednesday, August 31.—This has been a "red-letter" day with me, and one which I shall not soon forget, for my mind is clogged and my memory confused by what I have to-day seen. General Washburn and Mr. Hedges are sitting near me, writing, and we have an understanding that we will compare our notes when finished. We are all overwhelmed with astonishment and wonder at what we have seen, and we feel that we have been near the very presence of the Almighty. General Washburn has just quoted from the psalm:


"When I behold the work of Thy hands, what is man
that Thou art mindful of him!"

My own mind is so confused that I hardly know where to commence in making a clear record of what is at this moment floating past my mental vision. I cannot confine myself to a bare description of the falls of the Yellowstone alone, for these two great cataracts are but one feature in a scene composed of so many of the elements of grandeur and sublimity, that I almost despair of giving to those who on our return home will listen to a recital of our adventures, the faintest conception of it. The immense cañon or gorge of rocks through which the river descends, perhaps more than the falls, is calculated to fill the observer with feelings of mingled awe and terror. This chasm is seemingly about thirty miles in length. Commencing above the upper fall, it attains a depth of two hundred feet where that takes its plunge, and in the distance of half a mile from that point to the verge of the lower fall, it rapidly descends with the river between walls of rock nearly six hundred feet in vertical height, to which three hundred and twenty feet are added by the fall. Below this the wall lines marked by the descent of the river grow in height with incredible distinctness, until they are probably two thousand feet above the water. There is a difference of nearly three thousand feet in altitude between the surface of the river at the upper fall and the foot of the cañon. Opposite Mount Washburn the cañon must be more than half a vertical mile in depth. As it is impossible to explore the entire cañon, we are unable to tell whether the course of the river through it is broken by other and larger cataracts than the two we have seen, or whether its continuous descent alone has produced the enormous depth to which it has attained. Rumors of falls a thousand feet in height have often reached us before we made this visit. At all points where we approached the edge of the cañon the river was descending with fearful momentum through it, and the rapids and foam from the dizzy summit of the rock overhanging the lower fall, and especially from points farther down the cañon, were so terrible to behold, that none of our company could venture the experiment in any other manner than by lying prone upon the rock, to gaze into its awful depths; depths so amazing that the sound of the rapids in their course over immense boulders, and lashing in fury the base of the rocks on which we were lying, could not be heard. The stillness is horrible, and the solemn grandeur of the scene surpasses conception. You feel the absence of sound—the oppression of absolute silence. Down, down, down, you see the river attenuated to a thread. If you could only hear that gurgling river, lashing with puny strength the massive walls that imprison it and hold it in their dismal shadow, if you could but see a living thing in the depth beneath you, if a bird would but fly past you, if the wind would move any object in that awful chasm, to break for a moment the solemn silence which reigns there, it would relieve that tension of the nerves which the scene has excited, and with a grateful heart you would thank God that he had permitted you to gaze unharmed upon this majestic display of his handiwork. But as it is, the spirit of man sympathizes with the deep gloom of the scene, and the brain reels as you gaze into this profound and solemn solitude.

The place where I obtained the best and most terrible view of the cañon was a narrow projecting point situated two or three miles below the lower fall.[[H]] Standing there or rather lying there for greater safety, I thought how utterly impossible it would be to describe to another the sensations inspired by such a presence. As I took in this scene, I realized my own littleness, my helplessness, my dread exposure to destruction, my inability to cope with or even comprehend the mighty architecture of nature. More than all this I felt as never before my entire dependence upon that Almighty Power who had wrought these wonders. A sense of danger, lest the rock should crumble away, almost overpowered me. My knees trembled, and I experienced the terror which causes, men to turn pale and their countenances to blanch with fear, and I recoiled from the vision I had seen, glad to feel the solid earth beneath me and to realize the assurance of returning safety.

The scenery surrounding the cañon and falls on both banks of the Yellowstone is enlivened by all the hues of abundant vegetation. The foot-hills approach the river, crowned with a vesture of evergreen pines. Meadows verdant with grasses and shrubbery stretch away to the base of the distant mountains, which, rolling into ridges, rising into peaks, and breaking into chains, are defined in the deepest blue upon the horizon. To render the scene still more imposing, remarkable volcanic deposits, wonderful boiling springs, jets of heated vapor, large collections of sulphur, immense rocks and petrifications abound in great profusion in this immediate vicinity. The river is filled with trout, and bear, elk, deer, mountain lions and lesser game roam the plains, forests and mountain fastnesses.

The two grand falls of the Yellowstone form a fitting completion to this stupendous climax of wonders. They impart life, power, light and majesty to an assemblage of elements, which without them would be the most gloomy and horrible solitude in nature. Their eternal anthem, echoing from cañon, mountain, rock and woodland, thrills you with delight, and you gaze with rapture at the iris-crowned curtains of fleecy foam as they plunge into gulfs enveloped in mist and spray. The stillness which held your senses spellbound, as you peered into the dismal depths of the cañon below, is now broken by the uproar of waters; the terror it inspired is superseded by admiration and astonishment, and the scene, late so painful from its silence and gloom, is now animate with joy and revelry.

The upper fall, as determined by the rude means of measurement at our command, is one hundred and fifteen feet in height. The river approaches it through a passage of rocks which rise one hundred feet on either side above its surface. Until within half a mile of the brink of the fall the river is peaceful and unbroken by a ripple. Suddenly, as if aware of impending danger, it becomes lashed into foam, circled with eddies, and soon leaps into fearful rapids. The rocky jaws confining it gradually converge as it approaches the edge of the fall, bending its course by their projections, and apparently crowding back the water, which struggles and leaps against their bases, warring with its bounds in the impatience of restraint, and madly leaping from its confines, a liquid emerald wreathed with foam, into the abyss beneath. The sentinel rocks, a hundred feet asunder, could easily be spanned by a bridge directly over and in front of the fall, and fancy led me forward to no distant period when such an effort of airy architecture would be crowded with happy gazers from all portions of our country. A quarter of the way between the verge and the base of the fall a rocky table projects from the west bank, in front of and almost within reaching distance of it, furnishing a point of observation where the finest view can be obtained. In order to get a more perfect view of the cataract, Mr. Hedges and I made our way down to this table rock, where we sat for a long time. As from this spot we looked up at the descending waters, we insensibly felt that the slightest protrusion in them would hurl us backwards into the gulf below. A thousand arrows of foam, apparently aimed at us, leaped from the verge, and passed rapidly down the sheet. But as the view grew upon us, and we comprehended the power, majesty and beauty of the scene, we became insensible to danger and gave ourselves up to the full enjoyment of it.

Very beautiful as is this fall, it is greatly excelled in grandeur and magnificence by the cataract half a mile below it, where the river takes another perpendicular plunge of three hundred and twenty feet into the most gloomy cavern that ever received so majestic a visitant. Between the two falls, the river, though bordered by lofty precipices, expands in width and flows gently over a nearly level surface until its near approach to the verge. Here a sudden convergence in the rocks compresses its channel, and with a gurgling, choking struggle, it leaps with a single bound, sheer from an even level shelf, into the tremendous chasm. The sheet could not be more perfect if wrought by art. The Almighty has vouchsafed no grander scene to human eyes. Every object that meets the vision increases its sublimity. There is a majestic harmony in the whole, which I have never seen before in nature's grandest works. The fall itself takes its leap between the jaws of rocks whose vertical height above it is more than six hundred feet, and more than nine hundred feet above the chasm into which it falls. Long before it reaches the base it is enveloped in spray, which is woven by the sun's rays into bows radiant with all the colors of the prism, and arching the face of the cataract with their glories. Five hundred feet below the edge of the cañon, and one hundred and sixty feet above the verge of the cataract, and overlooking the deep gorge beneath, on the flattened summit of a projecting crag, I lay with my face turned into the boiling chasm, and with a stone suspended by a large cord measured its profoundest depths. Three times in its descent the cord was parted by abrasion, but at last, securing the weight with a leather band, I was enabled to ascertain by a measurement which I think quite exact, the height of the fall. It is a little more than three hundred and twenty feet; while the perpendicular wall down which I suspended the weight was five hundred and ten feet.
