"Know you," said the first Arab, "that your illness cost us the life of our sheik, Abbas-ibn-Rashid, who was ever your friend?"

"I know that he was killed," was the reply, "but he died as he would have wished, and you must all die at one time or another."

"That is indeed true both for you and for us," said the first speaker, "but I would have you know that I am now sheik in my uncle's place, and I have neither his generosity nor his kindness. I have sworn to avenge his death, not only by slaying his murderer, Faris of the Jelas curs, but also by demanding that you shall render up forthwith that for which you would have received 2000 kerans had you kept to your agreement."

"Fine words, Ahmed," replied the seer, quite unperturbed. "Yet pause before you act foolishly. You and your men have come here with naked spear points, which in itself is an insult to the goddess whom I serve. You come to this sacred spot prepared for robbery of the basest kind—robbery from an old man, unable to defend himself with weapons made by human hands. Now, look you, I take these eight beads from my rosary, and I shall let them fall one by one to the floor; when the fourth bead drops you will know that my appeal has reached the gods whom I serve; ere the sixth strikes the ground you must have gone out from this chamber; for, the seventh is the bead of ruin and destruction, and the eighth brings the avenging fire."

What was about to happen I could not conjecture; the old seer, now standing, broke the string of his rosary, and slowly counted out eight beads. I held my breath as I watched him, and wondered if I were dreaming. Faris laid his hand on my arm and held it as in a vice. Then the seer, muttering a few words, stretched out his hand with a bead between the finger and thumb. It dropped to the ground and, rebounding from the bricks, rolled away. The three Bedouins looked at one another and smiled; and Ahmed, rising, addressed the seer.

"Let fall your beads," said he, "and invoke your gods to the utmost. We know them not, and we curse them as vile impostors."

The seer did not vouchsafe a reply, but holding out his hand, let fall a second bead. A slight pause ensued, then the third bead dropped. It seemed to me that the Bedouins now showed some signs of wavering; they no longer smiled; and they shifted in their seats uneasily. The fourth bead was already between finger and thumb, and, like the others, it fell to the ground. Then the Bedouins rose, and I momentarily expected to see them hurl themselves on the strange figure confronting them. But the fifth bead had dropped before they moved, and as it struck the brick floor, it broke in pieces, and, as I thought, gave out some sparks. Whatever occurred was better seen by the Bedouins than by myself, and I noticed that all three of them recoiled. As the sixth bead was raised by the seer, I thought that I saw Ahmed clutch at his spear, but he and his companions now seemed unable to move. The sparks this time were unmistakable; and their effect on the Bedouins was to cause them to step hurriedly back, as if in flight. It was, however, too late, for the seventh bead left the seer's fingers immediately after the sixth; and the eighth followed the seventh as rapidly. In place of dropping this last one like the others, he hurled it with all his force at the very feet of the Arabs. It struck the ground with a report like that of a bomb, and instantly that portion of the floor seemed to open, and give forth great tongues of flame, which leaped up to the roof, and filled the whole chamber. It was a dreadful sight, and I could not restrain myself from shrieking aloud at the horror of it all.

"Fly," shouted Faris, clutching convulsively at my arm, "fly, before we also perish."

Great flames licked up the door in front of us, sweeping it away, then, bursting into the air, shot up, and cast a lurid glare over the ruins. By the light thus given, we were able to dash up the steps and through the piles of broken masonry, out of the hollow, with all speed. At last, when at a safe distance, we stopped, and turned to look back. The flames still poured forth, but now spasmodically, and the smoke grew thicker and blacker. Neither of us spoke, and from what I could see of his face, my companion was as much puzzled at what had occurred as was I. Dawn was approaching, and, as if afraid of the daylight, the flames died down, though the black smoke continued to belch forth through the doorway.

"Sheik," I said in a low voice, hardly daring to break the silence, "what was it?"
