But as the day went on, and the sun rose higher, Coppinger began clearly to have had enough of it, though he was very game, and insisted on going on much longer than was safe. I must say I didn’t like it. You see the drop was seldom less than eighty feet from the top of the cliffs. However, at last he was forced to give it up. I suggested marching off to Santa Brigida forthwith, but he wouldn’t do that. There were three more cave-openings to be looked into, and if I wouldn’t do them for him, he would have to make another effort to get there himself. He tried to make out he was conferring a very great favour on me by offering to take a report solely from my untrained observation, but I flatly refused to look at it in that light. I was pretty tired also; I was soaked with perspiration from the heat; my head ached from the violence of the sun; and my hands were cut raw with the rope. Coppinger might be tired, but he was still enthusiastic. He tried to make me enthusiastic also. “Look here,” he said, “there’s no knowing what you may find up there, and if you do lay hands on anything, remember it’s your own. I shall have no claim whatever.” “Very kind of you, but I’ve got no use for any more mummies done up in goatskin bags.” “Bah! That’s not a burial cave up there. Don’t you know the difference yet in the openings? Now, be a good fellow. It doesn’t follow that because we have drawn all the rest blank, you won’t stumble across a good find for yourself up there.” “Oh, very well,” I said, as he seemed so set on it; and away I stumbled over the fallen rocks, and along the ledge, and then scrambled up by that fissure in the cliff which saved us the two-mile round which we had had to take at first. I wrenched out the crowbar, and jammed it down in a new place, and then away I went over the side, with hands smarting worse at every new grip of the rope. It was an awkward job swinging into the cave mouth because the rock above overhung, or else (what came to the same thing) it had broken away below; but I managed it somehow, although I landed with an awkward thump on my back, and at the same time I didn’t let go the rope. It wouldn’t do to have lost the rope then: Coppinger couldn’t have flicked it into me from where he was below. Now from the first glance I could see that this cave was of different structure to the others. They were for the most part mere dens, rounded out anyhow; this had been faced up with cutting tools, so that all the angles were clean, and the sides smooth and flat. The walls inclined inwards to the roof, reminding me of an architecture I had seen before but could not recollect where, and moreover there were several rooms connected up with passages. I was pleased to find that the other cave-openings which Coppinger wanted me to explore were merely the windows or the doorways of two of these other rooms.
