"My name is Edgar Blagrove. I am the son of a merchant, whose place of business is in the great square. Who are you, and how did this business begin?"

"My name is Sidi Ben Ouafy. I am the son of a chief. My father's tribe live in the oasis ten miles east of the old lake. I was riding from the town when these two men, for whom there was, as you see, plenty of room in the road, staggered suddenly against me, whether with evil intent or merely to enjoy the pleasure of seeing me rolling in the dust, I know not. They nearly unseated me from the suddenness of the attack, and as I recovered I certainly struck at them with my whip. One seized me by the foot and threw me off my horse, and then, as you saw, they fell upon me, beat me, and were dragging me to the fountain to throw me in when you came up. Had they not heard your horse coming along they would, I believe, have killed me. Henceforth you are my brother; my horses and all that I have are yours, and every sword of our tribe would leap from its scabbard in your defence were it needed. To-morrow I will ride in again, and my father himself will assuredly come with me. I cannot speak of my gratitude now, my head is still dizzy with the blows they gave me; even yet I cannot understand how it was that these two men have thus fallen before you, and you with no weapon in your hands. Are they dead?"

"Not they," Edgar said scornfully; "they are wondering what has happened to them, and fear to move, not knowing that their own knives might not be driven into their hearts did they venture to rise. Well, good-bye, Sidi; I will see you off first; and I should advise you, when you ride into the town again, to bring your pistols with you. Like enough these scoundrels will try to get revenge for this defeat."

"I will do so. I know not why I did not carry them to-day. I will not only bring them, but two of my tribesmen shall ride with me. But methinks that you will be in greater danger than I shall, brother."

"I shall be on the look-out, and will, for a time, carry pistols with me; but I do not often go out after dark, and have no occasion ever to enter the streets where rogues of this sort live. As to an open attack, I have no fear of it; but I have no doubt that either of those scoundrels would plant a knife between my shoulders if they had a chance to do so."

Both the lads mounted their horses, and after a few words of farewell rode off in different directions. Not until the sound of the horses' hoofs died away did the two figures in the road move, then they sat up.

"What has happened, Zeno?"

"I know not, save that my head is ringing. I feel as if my jaws were broken, and my nose is so swelled that it seems as big as my head."

"And I can scarcely see from my eyes," the other said. "Cospetto, never before have I been thus handled!"

"We will kill him!" the other said furiously.
