“I don’t care what you want. Come alongside, and I’ll use this wrench on you!”

“Oh, no you won’t!”

Terry Walters slipped round the engine and tripped up the aviator. Before that irate person knew what was happening he found himself flat on his back with a hundred and sixty pounds of young American kneeling on his chest, menacing him with his own monkey-wrench.

“That’s not a nice way to talk to a lady!” Terry remarked dispassionately eyeing his victim. “Ask her pardon like a good little boy. Do it quickly, my friend, or I’ll plant this wrench in the middle of that bush you call a face!”

“I didn’t mean nossing,” the man grunted.

“Try again!” Terry whacked his captive’s shin with the wrench. “Also try to cut the double negatives. Our English teacher says they’re bad form and—”

Terry’s banter stopped with a yelp of pain as the man’s head jerked upward and his teeth snapped on the hand which held the wrench.

Dorothy, who had swum to within a few feet of the amphibian, saw Terry thrown to one side. Like cats, the boy and the man seemed to land on their feet—but now it was the strange aviator who held the monkey-wrench.

“Look out, Terry!” shrieked the girl as she saw the man’s arm swing upward.

The small deck forward of the lower wing section was far too narrow to permit dodging. Terry did the only thing possible under the circumstances to save himself. Three seasons on the football team of the New Canaan High had made that young man a quick thinker. He dove below the swinging blow and tackled the aviator just above his knees. It was a well aimed tackle and the two went hurtling overside to disappear with a splash.
