The ledge is scarcely large enough for tennis, it might be eight feet long and two or three feet wide; the name is just the overflow of the pretty wit of some early explorer. Above us rose threateningly the vertical rampart that separates Moss Ghyll and Steep Ghyll. We could see the jammed boulders a little higher up in our ghyll. They appear small from Hollow Stones, but from our ledge each looked almost as large as a church. Wastdale Church we had in mind. The opposite wall of the ghyll looked hopelessly inaccessible, and we were little surprised that so many before us had been content to look and return. The traverse into the ghyll again was not so easy. If the leader slipped it would require clever management of the rope on the part of the others to avoid an unwilling follow on, though I believe a party was once tested here in that manner--and survived the test. It was necessary to pass round a small buttress on to the scree bed of the gully. The first two steps were upwards, with just a steadying hold above for the hands. It was not desirable to keep too high, an unnecessary lengthening of the _mauvais pas_ that some climbers recommend. The footholds are not perfect; they are large, but slope the wrong way. When dry, the friction is ample to prevent slipping. Where the rocks are glazed, as I have good occasion to remember, the passage is distinctly dangerous, especially the return from the gully to the Tennis Court ledge. Thence, when all had rounded the corner safely, we walked up scree into the large cavern formed by the two jammed boulders. The one would of itself have formed a bridge across the gully, with a recess between it and the steep bed of the gully; the other, which is much larger, has fallen on to the first and roofed over the recess. When well within the cave we could see the ‘window’ high up between the two boulders, the one weak point by which the pitch could be attacked. I clambered up the interior of the cave and on to the window-sill. One of the others followed me, the third staying below to anchor the rope more firmly. From the window we could see the smooth steep wall on our right by which we were to traverse outwards. A couple of feet below our level we could observe that the rock formed a sharp horizontal edge six feet long, below which it overhung considerably. Just along this edge we were preparing to walk, using two steps that were sufficiently large for our needs. The first was the step cut by Dr. Collie. The second was at the further end of the short promenade, and was just capable of holding the toes of both boots. Starting with the right foot on the first step, the further end of the second step was taken in a long stride with the left. The right was then brought up to it, and the left reached round the corner at the end on to a respectable and satisfying foothold. The trick of balancing was not very difficult, providing of course that the body was kept as nearly as possible vertical. A tumble
