The city was likewise wrapped in profound silence, but just as Rob was turning away he saw a head project stealthily over the edge of the wall before him, and recognized in the features one of the Turks who had robbed him.
Finding no one awake except the boy the fellow sat upon the edge of the wall, with his feet dangling downward, and grinned wickedly at his former victim. Rob watched him with almost breathless eagerness.
After making many motions that conveyed no meaning whatever, the Turk drew the electric tube from his pocket and pointed his finger first at the boy and then at the instrument, as if inquiring what it was used for. Rob shook his head. The Turk turned the tube over several times and examined it carefully, after which he also shook his head, seeming greatly puzzled.
By this time the boy was fairly trembling with excitement. He longed to recover this valuable weapon, and feared that at any moment the curious Turk would discover its use. He held out his hand toward the tube, and tried to say, by motions, that he would show the fellow how to use it. The man seemed to understand, by he would not let the glittering instrument out of his possession.
Rob was almost in despair, when he happened to notice upon his hand the ruby ring given him by the chief. Drawing the jewel from his finger he made offer, by signs, that he would exchange it for the tube.
