He was signalling to someone on the brow of the precipice!
Open-mouthed I watched the result. The glare of his torch prevented me from distinguishing the crest of the rock distinctly, yet as I looked in the direction he was gazing I presently saw far away on the summit, glittering like a brilliant star, a bright light that seemed in answer to Omar's signals to appear and disappear rapidly, evidently flashing back a reply from the mysterious realm above.
Suddenly the distant light became totally obscured, and from Omar's lips there fell an expression of disappointment. His own fire-brand was burning but dimly, therefore, rushing to the embers, he drew another from the fire, blew upon it violently until it flamed, and then recommenced the puzzling signals, the system of which seemed very similar to those used in the British Army.
Again and again he repeated the long and short waves of the flaming torch, but no answering light appeared. All was dark upon the towering summit, that loomed up black and lonely against the deep vault of dark, star-lit blue. His was a weird figure, standing in the centre of the circle of uncertain light shed by the flambeau, watching eagerly, and waving his signals with untiring energy.
"Fools!" he cried aloud to himself. "They are so fearful of treachery that they feign not to be able to distinguish the name of their ruler."
But ere the words had fallen from his lips the star-like light again shone forth white, with intense brilliancy, but in a different position. It seemed to have moved along the brink of the precipice, nearer to us, and its whiteness had been somehow intensified. In appearance it was very similar to an electric search-light, and so powerful were its rays that they streamed forth in a long line of brilliancy that slowly swept the valley where the corpses of the Arabs lay piled until it reached us, illuminating our camp with a light almost bright as day.
Several minutes elapsed, and Omar, standing in the centre of the light, casting a long grotesque shadow behind, continued waving the word he was so desirous of signalling. In the meantime those who were working the light had undoubtedly ascertained the extent of our numbers, for very soon the light slowly travelled over the adjoining rocks, and even searched the further end of the valley; then suddenly it shed upon us again, and instantly became obscured.
Nothing daunted, Omar continued his signals until at last they were evidently noticed and read, for suddenly the light streamed forth again and commenced a series of vivid flashes that lit up the valley like shafts of lightning.
Thus came the answer, for next second Omar, overjoyed, and unable to contain himself, again cried aloud:
"Seen! Hurrah! At last!"
