right and thrust the left knee well into the crack. The position was one that could admit of no slip, the leg being sufficient to hold the body well in; and before quitting that favoured spot I untied the rope and slipped the free end through the hole at the back of the jammed stone before tying on again. The others had descended by this time to the platform and were taking in all the slack. Whatever the difficulty of the few remaining moves to the cave, I was insured against a big fall and could trust to the belaying of the little angular block that had so neatly adjusted itself to our needs. As a matter of fact the precaution was scarcely necessary, though eminently proper under the circumstances. The ledges above me were good and firm, and with the rope gently paid out from below I reached the cave without more trouble. The floor was sloping; but a comfortable and reposeful attitude could be indulged in, well at the back, far from the dripping eaves of the cave. But I had committed an error of judgment with the rope, threading the hole from above the jammed stone instead of from below, before tying the bowline round my waist. At the time the importance of that consideration had not occurred to me, but now in my ease, hauling up the slack between myself and the second, I felt a sudden jerk. The rope was wrapped completely round the jammed stone, whose angularity, that had before commended itself to the hands, now introduced so much friction that the rope would no longer slip freely round it. We were perplexed for a while, till our enterprising middleman, who had many times before offered a key to our difficulties, proposed climbing up as a leader, with the second rope attached to his waist, and the fixed rope above him used for steadying purposes whenever necessary. We knew that the jammed stone that fixed the upper rope could not be dislodged easily, and indeed I was able to hold on to my end and oppose any dangerous leverage. He climbed up with every confidence, and reached the crack safely. Then, repeating my movement with the left leg, he held on while disentangling my rope, tying himself to its lower end as soon as the complications were unravelled. A few moments more gave me a companion in the cave, and built, as it was, for two persons only, he mildly suggested my withdrawal for the benefit of the third man. Thence our method of advance was practically identical with Robinson’s. We had a little walk of six feet over towards the left wall of the gully, by ledges that lay on the very verge of a sheer drop of eighty feet to the foot of the pitch. Then the ascent was continued by a narrow crack that commenced in a somewhat sensational manner, not so much by reason of its difficulty as by the feeling of nothingness to fall back upon in case of a slip. The second was at my heels, and he was firmly braced up by the sole remaining tenant of the cave. Lifting the left leg as high
