The older and the newer caves and passages of Wookey Hole lie at five levels, one above the other like five storeys, the topmost of all representing the oldest channel of the subterranean Axe, which has in the course of ages forsaken first one and then the other, boring fresh passages in the Conglomerate. Of these five storeys, one alone, the nethermost, is known to the uninitiated visitor. Portions of the other four had been explored from time to time by Mr. Balch, who in 1903 made such discoveries of unknown continuations as fill us with hopes of penetrating deeply into the mysterious region beyond. Climbing into the Upper Series from a spot near the threshold of the Witch's Kitchen, we made our way eastward over dry rocks, and came speedily to the junction with another passage from nearer the cave mouth. Only a thin leaf of rock separates the two, for it is characteristic of all these upper passages that they run almost parallel to each other whilst rising to other levels. Altogether, we doubled back on our original direction three or four times, creeping through holes in the walls partitioning the corridors, and ascending to the top of several lofty bridges, formed by fragments that have fallen from roof and walls and wedged themselves securely. The construction of these bridges is often marvellous to see. In one case a number of rocks form an irregular arch, at the top of which a keystone wedges the whole cluster together. Obviously they must have fallen and come together practically at the same instant. This was what happened hard by with two great boulders that fell down the rift and caught each other in mid-air. Another impressive natural structure is known to explorers of Wookey Hole as the Spur and the Wedge. The huge horizontal peak of Limestone projecting into the chasm brings to mind a famous passage in Mr. Rider Haggard's _She_. This spot was the scene of a droll adventure that befell one of my companions years ago. With several other boys, he wandered into these passages, when suddenly the one candle they had with them went out. A boy had been commissioned to bring a supply of matches, but it was ascertained that he had only one left, which on being struck promptly went out. In this emergency, the lads could do nothing but sit still until help arrived. They had no food, and in trying to feel the time, they broke the hands of the only watch. They computed that they had been in durance three days when the rescue party reached the spot, but the protracted and hungry period of waiting turned out to be only eight hours. Their resting-place was the flat back of the pinnacle, with a 60-foot drop on one side and jagged rocks on the other.
