We had nearly gained the spot when to my dismay I saw a dozen of the worshippers, divining our intention, approaching from the opposite direction in order to cut off our retreat.

It was an exciting moment. Behind, was a mad, fanatical mob of five hundred men and women led by the dwarfs shrieking vengeance against us; before us were a dozen determined men ready to seize us and convey us to a horrible death in the throat of the gigantic representation of their sacred reptile. Even if we safely descended the steps, we knew not the secret means by which we might reach the earth's surface, nor did either of us remember the exact point where the long dark tunnel joined the wonderful cavern.

None, however, knew that Omar himself was one of my fellow fugitives, for the dwarfs, being consigned to a subterranean life perpetually, had never set eyes upon him, and therefore he had been unrecognized. Another moment, and I knew he must be detected by some of the devotees. If so, the hostile feeling against us would be intensified, and we should probably be torn limb from limb.

I had retained the lead in this race for life, and seeing retreat cut off by the group of men gaining the top of the steps before us I turned quickly, and, although fearing the worst, made a long detour. Determined to sell my life dearly, I drew my long knife from its velvet sheath, and gripped it, ready to strike a deadly blow in self-defence. Luckily I armed myself in time, for almost next moment a man of huge stature sprang forward from behind one of the columns of rock where he had been secreted and threw himself upon me, clutching me by the throat.

Scarce had his sinewy fingers gripped me, when, by dint of frantic effort, I freed my right arm, and with a movement quick as lightning flash, I buried my knife full in his breast. One short, despairing cry escaped him, and as he staggered back I dashed forward again, without turning to look at the result of the swift blow I had delivered. But I was desperate, and being compelled to defend my life, I do not doubt that my blow was unerring, and that my blade penetrated his heart.

Hindered thus in my flight my two companions had reached the edge of the precipice ahead of me, and were skirting it, when suddenly I saw a body of our pursuers approaching, and cried to them in warning. In dismay I noticed they took no heed of my words, but continued their swift flight right in the direction of those who sought our destruction.

"Take care, Omar!" I shouted, in English. "Can't you see those devils in front?"

But he answered not, and I was about to halt and give up all thought of escape, when I saw them both suddenly throw themselves on their knees on the edge of the abyss, and almost instantly disappear over the precipice.

They had found another flight of steps!

Eagerly I sprang forward, and in a few seconds found myself descending the rough face of the rock, scrambling desperately down into the yawning chasm with a wild horde of excited fanatics shrieking and yelling above.
