"We can't tell you that!" he said in a low tone. "We're not spies!"

CHAPTER XIII

A GREAT SURPRISE

From the tone in which the remark was made Jimmie understood that the speaker was referring contemptuously to either himself or Dave.

He thought that he recognized the voice, but could not at once determine the identity of the one who made the statement. Just at the moment there appeared to be a world of canvas and ropes wound about his head and body. He gasped for breath.

Struggling to free himself from the entangling mass of cloth that seemed to be smothering and weighing him down, the lad presently found an opening, through which he thrust his head. Blinking rapidly as he cleared his eyes from the dust that had arisen because of the sudden downfall of the tent, the lad gazed about in astonishment.

"Here, here; cut it out!" he cried as he felt a rough hand laid upon his ankle. "What do you think you are doing, anyway?"

"Aus!" a rough voice sounded in his ear.

For a moment Jimmie lay without making an effort to rise. He was trying to regain his sense of location that had been momentarily disturbed because of his fall and sudden change of scene.
