'We found,' says Dr. Collie, 'that below the great slab which formed the roof, another smaller one was jammed in the gully, which, stretching across from side to side, formed the top of a great doorway. Under this we passed and clambered up on to the top of it. Over our heads the great rock roof stretched some distance over the gill. Our only chance was to traverse straight out along the side of the gill, till one was no longer overshadowed by the roof above, and then, if possible, climb up the face of rock and traverse back again above the obstacle into the gill once more. This was easier to plan than to carry out; absolutely no hand-hold, and only one little projecting ledge jutting out about a quarter of an inch and about two inches long to stand on, and six or eight feet of the rock wall to be traversed. I was asked to try it. Accordingly, with great deliberation, I stretched out my foot and placed the edge of my toe on the ledge. Just as I was going to put my weight on to it, off slipped my toe, and if Hastings had not quickly jerked me back, I should instantly have been dangling on the end of the rope. But we were determined not to be beaten. Hastings' ice-axe was next brought into requisition, and what followed I have no doubt will be severely criticised by more orthodox mountaineers than ourselves. As it was my suggestion I must take the blame. _Peccavi! I hacked a step in the rock_--and it was very hard work. But I should not advise any one to try and do the same thing with an ordinary axe. Hastings' axe is an extraordinary one, and was none the worse for the experiment. I then stepped across the _mauvais pas_, clambered up the rock till I had reached a spot where a capital hitch could be got over a jutting piece of rock, and the rest of the party followed. We then climbed out of the gill on the left, up some interesting slabs of rock. A few days later the gill was again ascended by a party led by Mr. J. Collier. They did not follow our track to the left after the overhanging rock had been passed, but climbed straight up, using a crack which looks impossible from down below, thus adding an extra piece of splendid climbing to the expedition.'
