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.

"That of course; I know not who he was, but we shall doubtless find out. I can hardly believe even now that it was with his hand that he struck us—it was done so quickly. He was there—then I struck at him, when—paff!—and it seemed to me that the air was full of stars; then, paff again! my jaws cracked, I fell backwards, there was a crash, and the world seemed to have come to an end. And you, Giaccamo, what did he do to you?"

"It was like that, except that I only had one blow, and there was an end of it. I was drawing my knife when it came—how, I know not. My knife flew from my hand—there was a flash of fire from my eyes, and I was on the ground, and thought it best to lie there, lest that accursed young Arab should take it into his head to sheathe my knife in my body. The next time we will give the young fellow no chance to try those strange tricks upon us."

"You are right, Giaccamo; I would sooner fight against even Thomasso, who is the best knife-player in Alexandria, than face that fellow again. Who can he be, I wonder?"

Edgar rode home, and after seeing his horse taken into the stable, went into the house.

"I have found my boxing of use, father."

"How is that, Edgar?"

The lad told him what had happened.

"You were quite right to strike, my boy," his father went on when he had heard the story; "'tis likely enough that those ruffians would have killed the lad. There are fellows here who would do murder for the sake of a few copper coins; and, doubtless, those men thought that the young chief would have some trinkets about him that would pay them for their trouble. I am sorry that you did not let the Arab put his knife into them; it would have been a good riddance, for the town abounds with rascals of that kind—the scum of the Mediterranean, men who have made their native towns too hot to hold them, and have committed crimes untold. As it is, you will have to be careful; fellows of this kind are not of a forgiving nature, and will be patient enough to wait for their revenge, but sooner or later they will attempt to take it."

"It was so dark, father, that they can scarcely have seen my face."

"Perhaps not, but no doubt they were able to make out your figure, and there are very few better-class young Europeans here. You will have to be on your guard, lad; you had better always carry pistols with you. Clever as you may be with your fists, if you were attacked by half-a-dozen fellows with knives, you would stand but little chance with them. Don't be out after dusk; in daylight you are fairly safe. At any rate, you would be, if you avoid the rookeries, where the lower class of European inhabitants live. I have a brace of short-barrelled pistols up-stairs I will give you. I carried them at one time when things were very unsettled here. You have made two bitter enemies, but, on the other hand, you have made a friend who may be useful. These Arabs, when they once form a friendship, are as true as steel, and in the event of any fanatical troubles here, you would find a sure refuge among them. The lad's father, Aboo Ben Ouafy, I know a little of, as he has made purchases of me. His tribe is not a large one, but he himself is a fine fellow. As the lad told you, their head-quarters are in an oasis some eight or ten miles, I believe, east of the old site of Lake Mareotis. They, of course, like all those people, are frequently absent on hunting or plundering expeditions."

The next day Sidi and his father, followed by half a dozen tribesmen, halted in front of Mr. Blagrove's place of business, and the two former dismounted and entered. The Bedouin chief saluted the merchant gravely, while Sidi went up to Edgar, who was sitting at a table, for he now worked for some hours a day in his father's office, and who rose at the lad's approach, and held out his hand in English fashion.

"You are none the worse for our scrimmage last night, Sidi?" he said heartily.

"No harm was done," Sidi replied gravely. "I am glad of what happened, for it has given me a friend, a brother."

"I am glad too," Edgar replied, "for I too am happy to have gained a friend."

In the meantime his father was saying to Mr. Blagrove, "I have come, effendi, to thank you and your son for the assistance he rendered to my boy yesterday. I have no doubt that he saved his life, and that at the peril of his own. It is wonderful what my son tells me, that, with his hands alone he beat to the ground the two men who had attacked him, though they were armed with knives. I know not how it could be done, but since it was done 'tis plain that he must possess skill unknown to us. Sidi has called him brother, and henceforth I shall regard him as a son, and my tribe will be his should he need their services. I doubt not that the attack was made in order to gain the horse my son rode, which is one of famous breed, and would sell at high price at Cairo or any other of the large towns. I feel sure that they would have
