My guides were hardy, rough fellows, and did not mind these omissions of meals for a day together, and had often, as now, slept without camp-fires at night. As the object seemed to be a trial of endurance, I resolved not to compromit myself by appearing a whit less hardy than they did, and uttered not a word that might even shadow forth complaint. This was, however, a cold and cheerless spot at best, with the wide prairie for a pillow, and black clouds, dropping rain, for a covering.
The next morning, as soon as it was at all light, we followed down the dry gorge in which we had lain, to Findley's Fork—a rich and well-timbered valley, which we descended about five miles. As we rode along through an open forest, soon after entering this valley, we observed the traces of the work of the beaver, and stopped to view a stately tree, of the walnut species, which had been partially gnawed off by these animals. This tree was probably eighteen or twenty inches in diameter, and fifty feet high. The animals had gnawed a ring around it, but abandoned their work. It had afterwards been undermined by the freshets of the stream, and had fallen. Was it too hard a work? If so, it would seem that some instinct akin to reason came to their aid, in leading them to give up their essay.
There was now every appearance of a change of weather. It was cold, and a wintry breeze chilled our limbs. I thought my blood was as warm as that of my guides, however, and rode on cheerfully. At length, Holt and Fisher, of their own motion, stopped to kindle a fire, and take breakfast. We had still plenty of fresh venison, which we roasted, as each liked, on spits. Thus warmed and refreshed, we continued down the valley, evidently in a better philosophical mood; for a man always reasons better, and looks more beneficently about him, this side of starvation.
I observed a small stream of pure water coming in on the north, side, which issued through an opening in the hills; and as this ran in the general direction we were pursuing, the guides led up it. We were soon enclosed in a lateral valley, with high corresponding hills, as if, in remote ages, they had been united. Very soon it became evident that this defile was closed across and in front of us. As we came near this barrier, it was found that it blocked up the whole valley, with the exception of the mouth of a gigantic cave. The great width and height of this cave, and its precipitous face, gave it very much the appearance of some ruinous arch, out of proportion. It stretched from hill to hill. The limpid brook we had been following, ran from its mouth. On entering it, the first feeling was that of being in "a large place." There was no measure for the eye to compute height or width. We seemed suddenly to be beholding some secret of the great works of nature, which had been hid from the foundation of the world. The impulse, on these occasions, is to shout. I called it Winoca.[9] On advancing, we beheld an immense natural vase, filled with pure water. This vase was formed from concretions of carbonate of lime, of the nature of stalagmite, or, rather, stalactite. It was greyish-white and translucent, filling the entire breadth of the cave. But, what was still more imposing, another vase, of similar construction, was formed on the next ascending plateau of the floor of the cave. The water flowed over the lips of this vase into the one below. The calcareous deposit seems to have commenced at the surface of the water, which, continually flowing over the rims of each vase, increases the deposit.
The height of the lower vase is about five feet, which is inferable by our standing by it, and looking over the rim into the limpid basin. The rim is about two and a half inches thick. Etruscan artists could not have formed a more singular set of capacious vases.
The stream of water that supplies these curious tanks, rushes with velocity from the upper part of the cavern. The bottom of the cave is strewed with small and round calcareous concretions, about the size of ounce balls, of the same nature with the vases. They are in the condition of stalagmites. These concretions are opaque, and appear to have been formed from the impregnated waters percolating from the roof of the cavern. There are evidences of nitric salts in small crevices. Geologically, the cavern is in the horizontal limestone, which is evidently metalliferous. It is the same calcareous formation which characterizes the whole Ozark range. Ores of lead (the sulphurets) were found in the stratum in the bed of a stream, at no great distance north of this cave; and its exploration for its mineral wealth is believed to be an object of practical importance.
I had now followed the geological formation of the country far south-westwardly. The relative position of the calcareous, lead-bearing stratum, had everywhere been the same, when not disturbed or displaced. Wide areas on the sources of the Maramec, Gasconade, and Osage, and also of the Currents, Spring river, and Eleven-points and Strawberry, were found covered by heavy drift, which concealed the rock; but wherever valleys had been cut through the formation by the stream, and the strata laid bare, they disclosed the same horizontality of deposit, and the same relative position of limestone and sandstone rock.
