There was a larger party than he supposed in this encampment. In another minute the whole crowd would be in action.

"Hey, Mid!" hissed Rex.

He got no reply from his friend, but the individual from the second tent turned as quick as a flash and sprang to tackle him. The charge was so unexpected that Rex went down under the weight of his silent opponent. Whoever the fellow was he didn't shout for help.

Rex twisted and heaved, using every wrestling trick he knew to break the hold of his antagonist. It was like a band of steel about his middle. Rex was too plucky himself, however, to call again for his friend, as long as this stranger fought the battle in silence.

They rolled over and over upon the saturated ground. Rex realized that there was confusion inside the lighted tent. The cardplayers had jumped up and were stumbling over each other to get outside and investigate the disturbance.

"Whole pack will be on me in a minute!" thought the Walcott Hall youth, and the idea stirred him to additional effort.

He managed to get a grip on the other fellow's shoulders, and held him off. His thumbs sought the bunch of muscles and nerves at the joint of the upper arm and shoulder. Pressure here brought a pained grunt from his victim's lips.

His grip on Kingdon relaxed. Slippery as an eel in his bathing suit, the latter wriggled free, rolled over, and leaped to his feet.

Between him and the lighted tent loomed suddenly an unmistakably lanky figure. "Hold 'em in the tent, Jawn," Rex panted, "till I find out what sort of a thing this is that grabbed me. It strikes me it's deaf and dumb."

"Right-o!" agreed the big fellow, and a sudden smack upon the wet canvas, and a wild roar inside, betrayed the collision of the spare tent stake in Midkiff's hands athwart the parting fly of the main tent.
