Thus the merchants discoursed in the tent; but the guard, who was stationed around the camp, began to be uneasy. A considerable troop of armed horsemen was seen at a distance of half an hour's ride, and seemed to be making directly for the camp. One of the guard therefore went into the tent to announce that they would probably be attacked. The merchants conferred with one another as to what was to be done: whether they had better ride out and meet the attack, or await it in camp. The two eldest merchants were in favor of the latter course; but the fiery Muley and Zaleukos chose the first, and called on Selim to follow their example. But Selim quietly drew a small blue cloth, covered with red stars, from his girdle, tied it to a spear, and ordered one of the slaves to fasten it to the top of the tent, saying he would pledge his life that when the horsemen saw this signal they would draw off quietly. Muley placed no faith in the result, but the slave fixed the lance on top of the tent. In the meantime all those in camp had seized their weapons, and looked for the horsemen in intense expectancy. But they had apparently caught sight of the signal on the tent, as they suddenly changed their course, and moved off from the camp in an opposite direction. The merchants gazed in wonder, now at the vanishing horsemen, and then on Selim. But he stood before the tent, looking out unconcernedly over the plain, as if nothing unusual had happened.

"You rate my power much higher than it is," answered Selim Baruch. "I provided myself with this token when I fled from captivity. What it signifies, I do not know myself; only this much I do know: that whoever travels with this sign stands under powerful protection." The merchants thanked Selim and called him their deliverer; and really the number of the horsemen was so great that the caravan could not have resisted them very long. With lighter hearts the merchants laid down to rest; and when the sun began to set, and the evening breeze blew over the plains of sand, they broke camp, and resumed their journey. The next day they camped within a day's march of the end of the desert. When the travelers had gathered once more in the large tent, Lezah the merchant began to speak:
