I had quitted the gully by this variation three years before, and wanted both on my own account and that of my friends to work out the alternative route. I started up the right wall, at first steadied by the left, but soon found myself too far out of the chimney to feel at all comfortable. Thirty feet up was a jammed stone blocking the narrow way, apparently very effectually. But we had heard of a possible wriggle behind the jammed stone, and with a reprehensible lack of daring I made a traverse to the chimney again, and began working up it with back and knee in the orthodox manner. The situation was safe enough, but the effort of lifting oneself inch by inch was supremely fatiguing, and when I discovered the hole behind the boulder to be about half my minimum sectional area I began to regret the scheme. But it was too late to return, and with a dread fear of closing up the ‘through’ route for ever, I straightened out one arm above my head and thrust it through the hole. Fortunately I had no camera sack to hold me back, a frequent source of annoyance in a tight place. Here we were all travelling light, and I had nothing to thrust through the aperture but a limp body that was at every moment lessening its rigidity. As soon as both shoulders were well in, the rest followed more easily by vigorous prisings with the elbows, which are so useful in upward thrusting. Dragging myself into a standing position on the jammed boulder, I called on the others to follow. They chose the outside course, making two little détours out and back on the vertical wall, probably the exact plan adopted by Dr. Collier in the first ascent. My position in this little ‘sentry-box’ was secure, and the rope could be manipulated with all necessary care till the three of us were gathered close together in the tiny recess. Then we had a somewhat easier scramble up the next vertical portion of the chimney, to pass some small jammed stones twenty feet higher. We used the same wall and found the footholds in it more obviously arranged for our convenience. The first climber had surely a bad time of it on this wall, seeing that it was all moss-covered, and required an immense amount of preliminary clearing before the holds could be discerned. But moss has had no chance of growing there for the last four years, and we had none to trouble us. A couple of minutes carried us from the sentry-box to the top of the next pitch. The slope of the ghyll suddenly became easier, scree led to a short and easy rock pitch, somewhat spoilt by loose stones, and then a walk to the top brought us in contact with friends and the commissariat.
