My presence of mind caused me just at that instant to grip the ledge above, otherwise I, too, must have gone with my unstable resting-place. It was indeed a narrow escape, and as clinging on with my hands, my legs again swinging in mid air, I heard the heavy rock, weighing perhaps a ton, strike a projection under me and then crash down, carrying all before it. There was an appalling shriek from below, and I dreaded to turn my gaze downward, fearing that my companions had been swept away by the great mass of stone. At last, however, I looked in trepidation and was gratified to notice that the projection struck by the rock had been left by the man preceding me, and that the course of the descending stone had been altered so that all had escaped. "Careful up there!" shouted Omar angrily. "Don't spring upon the steps, or they will become loosened like that one. It might have swept the whole lot of us into the valley if its course had not been turned. Lower yourselves slowly--very slowly--take plenty of time." "I did it, Omar," I cried breathlessly. "It was an accident. I could not avoid it, and nearly fell, too." But it was apparent that my voice did not reach him, for he slowly lowered himself over the next projection, and continued giving directions to the men who followed, while I, with the next ledge fallen away, was compelled to let myself drop a distance of about nine feet on to one that seemed far below. From that point the descent became much easier, although during the two hours it occupied I stumbled and nearly lost my foothold many times. My feet and hands were covered with blood, my elbows were severely grazed, and from my knees the skin was torn by the constant scrambling over the edges of the ledges. Truly the approach to the Land of the Great White Queen was fraught with a myriad dangers. When about half-way down the steep rock another piercing shriek broke forth immediately below me, and glancing down I saw one of our black companions who had dropped from one ledge to the next lose his footing, stumble, and fall headlong into the great chasm. Cries of horror escaped us as we saw him strike a rugged ledge of rock far below, rebound, and then fall head foremost to the rock's base, his skull already battered to a pulp. This terrible lesson was heeded by everyone, and for fully half an hour the silence was almost complete, save for the gasps and hard breathing of our followers as they toiled onward down the steep face of the gigantic rock.
