"Enough, sheik," I replied, "I will accompany you whenever you are ready to make the journey."

"It is well," said Faris. "I did not misjudge my man. We will have supper, and start with the moon an hour later. But you cannot go in those clothes of yours; the seer would be afraid of you. You shall wear garments which Sedjur and I will lend you."

Poor Edwards! I can see his face now. How he argued with me about my madness in thinking of such a crack-brained expedition! But he argued in vain, and when he saw that I was too obstinate to listen to him, he changed his tone and did all he could to help me prepare for my ride, dressing me up in my borrowed clothes, packing my light saddle-bags, and insisting on stuffing my pockets with enough revolver ammunition to wipe out half the Bedouins of the desert. I handed him over my money belt, for safe keeping; gave him instructions about returning to Baghdad if I failed to put in an appearance within a certain time; then, after grasping his hand, I mounted my little horse, and rode off by the side of the sheik.

We followed no visible track, but my companion never hesitated. Occasionally he looked up at the stars, but otherwise he sat motionless in the saddle, forging ahead at a fair pace hour after hour. I kept close on his heels, with my eyes intent on the blade of his spear, which was visible high above his head. I did not dare to break the silence, as I had been warned that at any moment we might run across Bedouins who would probably prove enemies. Throughout that whole night, I may say, I rode with my heart in my mouth, and with my hand on my revolver. When the moon had sunk, the darkness was intense, and Faris slackened his speed, and more than once dismounted, to place his ear to the ground and listen. At dawn we halted on a rise, from which we could see the whole country for many miles around, when the sheik told me to get an hour's sleep while he watched; and I required no second bidding. On being awakened, I found my companion preparing to continue the journey; and after eating some dried dates and small cakes, we set out again, just as the sun commenced to rise over the boundless plain. No incident occurred to break the weariness of that day's ride; no human being, no beast, no bird was visible at any time; but before us always lay the mirage of distant water and the reflections of many buildings. Sometimes we halted to rest the horses and to snatch a meal or a nap; but such halts were of short duration, as the sheik insisted on pushing with all haste through what he now explained was a waterless region. We had almost expended on our horses and ourselves the water that we carried in our water-skins, and it was, therefore, a relief, at sundown, to see before us a far extending lake and marsh, which my friend assured me was no deceitful mirage. Tired as I was, I fully appreciated the delightful change of scene, as we rode through the scrub and green grass bordering the swamp, flushing snipe and waterfowl at almost every step.

"Are you sorry that you came?" asked the sheik, as we watered our gallant little beasts.

"No," I replied, "this alone is well worth it all. But, tell me, how far have we yet to go? I confess to you that I feel that I am in very truth a townsman, and not made of the same stuff as your horses and yourselves."

Faris smiled, and it was a pleasure to see his face relax, for throughout our ride he had worn a hard set expression, with eyes ever keen and restless. I knew, from the change, that he was no longer anxious, and he apologised profusely for having taxed my powers of endurance so highly.

"The worst is over," he said. "Because of the water, it was advisable to hurry. By midnight we shall have accomplished our journey."

It wanted yet an hour of midnight when, having ridden for some miles beyond the marsh, the moon showed us that we were entering extensive ruins. After picking our way through the débris of stone and brickwork for a considerable distance, the sheik stopped, and taking out some cords, thrust his spear into the ground and fastened our horses to it.

"Now listen," said he. "Twice will I call the owl, and once the jackal. If the cry of the hyæna comes back in reply all is well, and we can proceed."
