We saw, this day, the Grotto and the Deserted Chamber. Few visitors attempt the grotto, the entrance to it being in one part only a foot and a half high. We were obliged, not only to go on hands and knees, but to crawl lying flat. It is a sensation worth knowing, to feel oneself imprisoned in the very heart of a mountain, miles from the sun-light, and with no mode of escape but the imperceptible hole which a child might block up in five minutes. Never was there a more magnificent prison or sepulchre. Whether the singularity of our mode of access magnified to our eyes the beauties we had thereby come into the midst of, or whether Nature does work most con amore in retired places, this grotto seemed to us all by far the most beautiful part of the cave. The dry sandy floor was pleasant to the tread, after the loose limestone; the pillars were majestic; the freaks of nature most wild and elegant. The air was so fresh and cool that, if only a Rosicrucian lamp could be hung in this magnificent chamber, it would be the place of all others in which to spend the sultry summer's day,—entering when the beauties of the sunrise had given place to glare, and issuing forth at the rising of the evening star.

On our way to the Deserted Chamber, we cut off half a mile by a descent through a crevice, and a re-ascent by another. We were presently startled by the apparition of two yellow stars, at what appeared an immeasurable distance. In this cave, I was reminded, after a total forgetfulness of many years, of the night-mare visitations of my childhood; especially of the sense of infinite distance, which used to terrify me indescribably. Here, too, the senses and the reason were baulked. Those two yellow stars might have been worlds, many millions of miles off in space, or,—what they were,—two shabby lamps, fifty yards off. A new visitor had arrived; and the old man of the solitary house had brought him down, in hopes of meeting our larger party. One of the gentlemen presently slipped on the loose stones, and fell into a hole, with his back against a sharp rock; and he seemed at first unable to rise. This was the only misadventure we had; and it did not prove a serious one. He was somewhat shaken and bruised, and rendered unwilling to go with the rest to the Bottomless Pit: but there was no eventual injury. He and I staid in the Deserted Chamber, while our companions disappeared, one by one, through a crevice, on their way to the pit. The dead silence, and the glimmer of our single lamp, were very striking; and we were more disposed to look round upon the low-roofed apartment, piled with stones as far as the eye could reach, than to talk. I tried to swallow a piece of bread or cake, very like a shoe-sole, and speculated upon these piles of stones;—by whose hand they were reared, and how long ago. There is much cane—doubtless, once used for fuel—scattered about the deeper recesses of the cave; and these stones were evidently heaped up by human hands: and those not Indian. It is supposed that this cave was made use of by that mysterious race which existed before the Indians, and of which so many curious traces remain in the middle States of the West; a race more civilized, to judge by the works of their hands, than the Indians have ever been; but of which no tradition remains.

Our party returned safe, and refreshed by a draught of water, better worth having than my luncheon of bread. When we left the cave, our guides insisted upon it that we had walked, this morning, ten or eleven miles. I pronounced it four. Others of the party said seven; and the point remains unsettled. We all agreed that it was twice as much as we could have accomplished in the heat above ground; and perhaps the most remarkable walk we had ever taken in our lives. Our hostess was with us the whole time; and it was amusing to see in her the effect of custom. She trod the mazes of this cave just as people do the walks of their own garden.

The gush of sun-light pouring in at the mouth of the cave, green and soft, as we emerged from the darkness, was exquisitely beautiful. So was the foliage of the trees, after the rigid forms which had been printing themselves upon our eye-sight for so many hours. As we sat at the entrance, to accustom ourselves to the warm outward air, I saw, growing high in the steep woods, the richest of kalmias, in full bloom. One of the gentlemen ran to bring me some; and when it came, it was truly a feast to the eye. How apt are we to look upon all things as made for us! How many seasons has this kalmia bloomed?

We were truly sorry to bid farewell to our motherly hostess, and her "smart" sons. Theirs is a singular mode of life; and it left nearly as vivid an impression on our minds as their mighty neighbour, the cave. If any of us should ever happen to be banished, and to have a home to seek, I fancy we should look out for a plot of green sward, among flowering kalmias, near the mouth of an enormous cave, with humming birds flitting about it by day, and fire-flies and summer lightning by night.

In strong contrast in my mind with such a scene as this, stands a gay encampment in the wilderness, at which I soon after arrived. The watering places among the Virginia mountains are as new and striking a spectacle as the United States can afford. The journeyings of those who visit them are a perpetual succession of contrasts. I may as well give the whole journey from Cincinnati to the eastern base of the Alleghanies.

We left Cincinnati at noon on the 25th of June: as sultry a summer's day as ever occurs on the Ohio. The glare was reflected from the water with a blinding and scorching heat; and feather fans were whisking all day in the ladies' cabin of our steam-boat. Hot as it was, I could not remain in the shady cabin. The shores of the Ohio are so beautiful, that I could not bear to lose a single glimpse between the hills. It is holiday-travelling to have such a succession of pictures as I saw there made to pass noiselessly before one's eyes. There were the children running among the gigantic trees on the bank, to see the boat pass; the girl with her milk-pail, half way up the hill; the horseman on the ridge, or the wagoner with his ox-team pausing on the slope. Then there was the flitting blue jay under the cool shadow of the banks; the butterflies crossing the river in zig-zag flight; the terrapins (small turtle) floundering in the water, with their pert little heads above the surface; and the glancing fire-flies every night.

On the afternoon of this day, we were met by the storm which swept over the whole country, and which will be remembered as having caused the death of the son of Chief-Justice Marshall, at Baltimore, on his way to his dying father. I watched, from the deck, the approach of the storm. First, the sky, above the white clouds, was of a dark grey, which might have been mistaken for the deep blue of twilight. Then a mass of black clouds came hurrying up below the white. Then a flash escaped from out of the upper grey, darting perpendicularly into the forest; and then another, exploding like the four rays of a star. I saw the squall coming in a dark line, straight across the river. Our boat was hurried under the bank to await it. The burst was furious: a roaring gust, and a flood of rain, which poured in under our cabin door, close shut as it was. All was nearly as dark as night for a while, and all silent but the elements. Then the day seemed to dawn again; but loud peals of thunder lasted long, and the lightning was all abroad in the air. Faint flashes now wandered by; and now a brilliant white zig-zag quivered across the sky. One splendid violet-coloured shaft shot straight down into the forest; and I saw a tall tree first blaze and then smoulder at the touch. A noble horse floated by, dead and swollen. When we drew out into the middle of the river, it was as if spring had come in at the heels of the dog-days; all was so cool and calm.

The company on board were of the lowest class we ever happened to meet with in our travels. They were obliging enough; as everybody is throughout the country, as far as my experience goes; but otherwise they were no fair specimens of American manners. One woman excited my curiosity from the beginning; but I entertained a much more agreeable feeling towards her when we parted, after several days' travelling in company. Her first deed was to ask where we were going; and her next, to take my book out of my lap, and examine it. Much of the rest of her time was occupied in dressing her hair, which was, notwithstanding, almost as rough as a negro's. She wore in her head a silver comb, another set with brilliants, and a third, an enormous tortoiseshell, so stuck in, on one side, as to remind the observer, irresistibly, of a unicorn. She pulled down her hair in company, and put it up again, many times in a day, whenever, as it seemed to me, she could not think of anything else to be doing. Her young companion, meantime, sat rubbing her teeth with dragon-root. The other cabin company seemed much of the same class. I was dressing in my state room between four and five the next morning, when an old lady, who was presently going ashore, burst in, and snatched the one tumbler glass from my hand. She was probably as much amazed at my having carried it out of sight as I was at her mode of recovering it.

I loved the early morning on the great rivers, and therefore rose at dawn. I loved the first grey gleams that came from between the hills, and the bright figures of people in white, (the men all in linen jackets in hot weather,) on the banks. I loved to watch the river craft; the fussy steamer making rapid way; the fairy canoe shooting silently across; the flat-boat, with its wreath of blue smoke, stealing down in the shadow of the banks, her navigators helping her along in the current by catching at the branches as they passed: and the perilous looking raft, with half-a-dozen people on it, under their canopy of green boughs, their shapeless floor bending and walloping in the middle of the stream. I loved the trees, looking as if they stood self-poised, their roots were washed so bare. I loved the dwellings that stood behind their screen, those on the eastern bank seeming fast asleep; those on the western shore gay with the flickering shadows cast on them by the breezy sunrise through the trees.
