When the food was ready, Matt asked Siwash to release his hands so that he could help himself. But Siwash refused, and the prisoner was compelled to take his food from the ruffian's hairy paws.

A change appeared to come over Siwash Charley. He was moody and reflective, and kept his pipe going continuously.

Leaning back against the earthen wall of the room, he surrounded himself with a fog of vapor, which, because of the poor ventilation of the dugout, almost stifled Motor Matt.

The sun went down in a blaze of red, night fell, and Siwash closed the door and lighted the lamp. He neglected to curtain the window, however, which may have been an oversight on his part.

Matt fell to musing upon the aëroplane, and about the watch which he had left on the aëroplane seat.

Would anything happen to the machine while he was a prisoner in the hands of Murgatroyd and Siwash? He roused up suddenly.

"Siwash," he asked, "what's going to be done with that flying machine?"

"I've had all I want out o' you," growled the ruffian, with savage emphasis. "If ye know when ye're well off, ye'll hush."

Matt "hushed." Frogs began to croak, and their husky voices came faintly to the prisoner's ears. Somewhere inside the dugout a cricket chattered. A rat ran over Matt's feet and a lizard crawled slowly along the earthen shelf at his side.
