To return to the separating line that suggested this digression. Those who have sought to define it theoretically have been of the foolish ones, for it has no absolute position for mankind. Each individual possesses a line of his own, and at first in looking for it he causes it to re-arrange itself. What was once impossible for him becomes easy. But his search is more rapid than its advance, and a time comes when he realizes that he is perilously near; and in wisdom he vows evermore to keep at so many feet or centimetres (according to his choice of units) from its nearest point. The nearer he habituates himself to approach, the oftener does he discover some obvious retreat of his line. Those who live far from it find that it can narrow its limits. Which things are an allegory, for this line is a closed curve and limits us in all directions, only one of which leads to rock-climbing. Our walk along the foot of the Scawfell wall by the Rake’s Progress showed three breaks in the cliff after we left Steep Ghyll. The first marked Moss Ghyll, the second Keswick Brothers’ Climb, the third Collier’s Climb. The history of Moss Ghyll and its gradual yielding to the persistent attacks of active parties has been recorded in the first section. The news of its ascent came as a surprise to all who knew the place, so great a surprise that no room was left for wonderment when Dr. Collier a few months later proved the practicability of his route. But whereas Moss Ghyll became popular in a week by reason of the writing-up it immediately received, Collier’s Climb was almost untouched for three years. The unknown is always the most terrible, and the brief note in the Wastdale climbing book recording its first ascent left much to an anxious imagination. Queer tales were told round at the inn of men who were flung back over the Rake’s Progress after rising only ten feet. Even Dr. Collier was reported to have said he never wished to see the place again. Report was inaccurate, but that made no difference. I candidly admit that there seemed little chance of ever getting up such an awful wall. It was not till I found myself twenty feet up the crack that the attack seemed in the least degree hopeful.
