The only approach to the Gulf is over the hill-tops; and the entrance in past times, while it was still a cave, must have been a sink-hole in the roof of the largest chamber. This chamber is now the upper end of the Grand Gulf, and into it we descended by a rugged path, sufficiently difficult to maintain expectations of grandeur that are not doomed to disappointment. The precipitous walls, two hundred feet in height, bear a faithful record of the energy of circling floods; but instead of frowning, as some good people persistently accuse all noble heights of doing, they seem to look with conscious pride towards the windings of the great rough chasm, where every available spot has been seized on as a homestead for some form of vegetation. All the great, dark rock masses that interfere with easy progress along the lowest depth, were surrounded by a feathery setting of blooming white agaratum; and each turn in the winding course reveals new charms of rock and verdure with their varying lights and shadows until the crowning glory is reached at the Natural Bridge, about twelve hundred feet from the upper end of the cañon. This bridge is magnificent. It was impossible to secure photographs because the abrupt curve by which it is approached gave no point of view for a small camera; and it was equally impossible to reach desirable points for taking measurements, but the open arch is not less than twenty feet wide and considerably more than that in height. From the floor or bed of the Gulf to the road that crosses the bridge is more than two hundred feet. The passage under the bridge makes a curve, the shortest side of which measures exactly two hundred and nineteen feet, and as the width varies from twenty to forty feet, the other side is longer. Most of the floor is flat and level as also is the ceiling, the greatest irregularities being along the wall of greater length which shows at what points the rushing water has spent its force. No water flows through here now except in times of heavy rainfall. The other end of the bridge has a somewhat smaller span but is very handsome, and the outward views from both are exceedingly fine. After traversing about four hundred feet more of the beautiful, high-walled Gulf, we stood before the grand entrance to the cave, which is strikingly similar to the first arch of the bridge. The only picture I was able to get was taken from the slope of the Bridge-crown, one hundred feet below the road, and merely gives a suggestion of the magnificence waiting peacefully for the crowds of eager and enthusiastic sight-seers who will in the near future rush to this charming region in the "Land of the Big Red Apple."

My companions were the same as mentioned in the preceding chapter, a nephew, James Arther Owen, and an obliging, tall young man of twenty, who acted as guide and driver.

Relieving ourselves of all superfluous burdens just within the cave entrance, we lighted candles and sat down to wait for our eyes to adjust themselves to the changed condition, from brilliant sunlight to absolute darkness, broken only by the feeble strength of three candles. It was noticeable that in the moist atmosphere of the Missouri caves, three candles were not more than equal to one in the dry caves of South Dakota.

Very soon we were able to continue the inspection of our surroundings, and the large passage we were in would more properly be called a long chamber, of irregular width but averaging about thirty feet. This ends abruptly nearly five hundred feet from the entrance, but a small passage scarcely more than six feet high runs off at right angles, and into this we turn. It is not quite so nearly dry as the outer chamber, and at a distance of less than one hundred feet we suddenly come to the end of dry land at an elbow of the silently flowing river whose channel we had almost stepped into. The ceiling dipped so we were not able to stand straight, and the guide said he had never gone farther; but to his surprise here was a light boat which I am ready to admit he displayed no eagerness to appropriate to his own use, and swimming about it, close to shore, were numerous small, eyeless fish, pure white and perfectly fearless; the first I had ever seen, and little beauties.

By burning magnesium ribbon we saw that the passage before us was a low arch and occupied from wall to wall by water, the direction of the flow being into another of somewhat greater size at right angles to that by which we had come, and at the mouth of this lay the boat. The distance we could see in either direction was of tantalizing shortness, and the boat was provided with no means of guidance or control, save an abundance of slender twine which secured it to a log of drift from the outside; so I decided to leave my companions in charge of the main coil of twine while I went on an excursion alone, there being not much evident cause for apprehension as no living cow could ever have made the trip to this favored spot.

Although the water looked perfectly placid, the boat drifted with surprising speed, so that the two scared faces peering after me were soon lost sight of. The channel was nowhere more than six feet wide, consequently as the boat inclined to drive against either wall I was able with care to keep it off the rocks with my hands, and in the same way guide it around the sharp turns in safety. After several of these turns there appeared the mouth of a passage so much smaller that the roof was only twelve inches above the sides of the boat and I could touch both walls at the same time. By running the boat across this it was held in place by the current, and I could sit at ease and enjoy the position, which even the least imaginative person can readily conceive to have been a novel one.

The small eyeless fish had been noticeable in the water everywhere but now came swimming about the boat in an astonishing multitude, and as unconscious of any possible danger as bees in a flower garden. Having no eyes, they were naturally undisturbed by the light, so the candle could be held close to the water for a satisfactory examination of the happy creatures.

They bore a striking resemblance to minnows, although a few were larger, and it is claimed that four or five inches are sizes not unusual, but they happened not to be on exhibition. Even dipping a hand into the water in their midst occasioned no alarm, and they might have been caught by dozens.

The guide now loudly called that he had fears of the twine being cut on the sharp edges of rock, and that cutting off all possibility of the boat's return, which being sufficiently reasonable, explorations were indefinitely suspended, and a landing soon made. The camera and flash-light were then prepared for taking a view, and a point of light being needed to work by the nephew was asked to sit in the boat with his candle, to which he readily consented; but judging from the developed picture it may be doubted if his pleasure at the time was extremely keen.

On leaving the cave the guide said it would not be necessary to return to the upper end of the Gulf in order to reach the surface, as the ascent could be made in another place; and leading the way to the left of the entrance he started up the nearly perpendicular wall, more than two hundred feet high, by a sort of "blind trail" that would have caused a mountain sheep to sigh for wings, but it was very beautiful.
