We issued into a good-sized passage. Immediately on the left a twisting fissure went down to the head of the first perpendicular drop; but, leaving this for a while, we spent nearly an hour exploring the lofty chamber straight ahead of us. It rises to an unknown height in a vertical fissure, narrowing gradually. At the bottom is a deep cutting, which some of us passed by back and knee work, at a height above the floor. On the left, that is the eastern, wall are openings into a parallel tunnel with good stalactites. At the far end both this tunnel and the passage itself are blocked with clay and gravel.[3] On our second visit, a day or two later, I explored a tunnel in the other wall 10 feet from the floor. It led into another of the vast sloping fissures already described, which I was too much exhausted to explore very far. These fissures, all inclined at the same angle, and either parallel or else lying in one plane, are most impressive features of the Eastwater Cavern; their extent is evidently enormous, and it seems as if only a few frail pillars of jammed stones served to prevent the great mass of the hill from settling down and crushing roof and floor together. On a more minute survey it may turn out that these are all portions of one huge fissure, merely partitioned off by different chokes. [3] Recently, October 1906, Mr. Balch dug through an obstruction here and entered a vast fissure chamber, which he climbed to a height of 150 feet: it has a remarkable shaft as its outlet. It was four in the afternoon when we entered the twisting fissure leading to the first vertical descent, and two of the party had now to return. Through an oversight in not bringing a short rope for harnessing the pulley, nearly two hours were spent in rigging up the tackle, the situation being awkward for letting men down safely. We were ensconced in a little chamber, the boulder floor of which opened into the top of a narrow rift widening downwards, where, about 60 feet beneath, the walls funnelled into a yawning pit 60 feet deep. This pit had been explored previously, and was found to be choked at the bottom; it formed a safe and certain receptacle for anything lost or dislodged by persons descending the cliff above it. The configuration of our hole was such that only one man at a time could get a steady pull on the life-line, which ran over a pulley. A manilla rope was therefore let down from the same belaying-pin, for a man to climb up and down by, so far as he was able, the life-line being used merely as a safeguard. One by one the explorers dropped over into the abyss. The last three or four had the best of it, since, with a hauling party below, full use could be made of the pulley.
