The Master Key [33]
"Those fellows were too cowardly to take part in a fair fight," declared the boy; but he was much disappointed, nevertheless, as he felt very helpless without the electric tube or the traveling machine.
The Tatar chief now called Rob to his tent and presented him with a beautiful ring set with a glowing pigeon's-blood ruby, in acknowledgment of his services. This gift made the boy feel very proud, and he said to the chief:
"You're all right, old man, even if you do look like a pirate. If you can manage to capture that city, so I can get my electrical devices back, I'll consider you a trump as long as I live."
The chief thought this speech was intended to express Rob's gratitude, so he bowed solemnly in return.
During the night that followed upon the first engagement of the Turks and Tatars, the boy lay awake trying to devise some plan to capture the city. The walls seemed too high and thick to be either scaled or broken by the Tatars, who had no artillery whatever; and within the walls lay all the fertile part of the oasis, giving the besieged a good supply of water and provisions, while the besiegers were obliged to subsist on what water and food they had brought with them.
Just before dawn Rob left his tent and went out to look at the great wall. The stars gave plenty of light, but the boy was worried to find that, according to Eastern custom, no sentries or guards whatever had been posted and all the Tatars were slumbering soundly.
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.
The Turk was much pleased with the idea, and nodded his head repeatedly, holding out his hand for the ring. Rob had little confidence in the man's honor, but he was so eager to regain the tube that he decided to trust him. So he threw the ring to the top of the wall, where the Turk caught it skilfully; but when Rob held out his hand for the tube the scoundrel only laughed at him and began to scramble to his feet in order to beat a retreat. Chance, however, foiled this disgraceful treachery, for in his hurry the Turk allowed the tube to slip from his grasp, and it rolled off the wall and fell upon the sand at Rob's very feet.
The robber turned to watch its fall and, filled with sudden anger, the boy grabbed the weapon, pointed it at his enemy, and pressed the button. Down tumbled the Turk, without a cry, and lay motionless at the foot of the wall.
Rob's first thought was to search the pockets of his captive, and to his delight he found and recovered his box of food tablets. The Record of Events and the traveling machine were doubtless in the possession of the other robbers, but Rob did not despair of recovering them, now that he had the tube to aid him.
Day was now breaking,
