Andy was demonstrating his famous "double-hammer-grip-half-Nelson-three-quarter-leg-lock-hold-trip," as it was afterward christened.
"You just put up your right arm so," said Andy to John North, "and then you stick out your left foot, and then you take hold of the other fellow's left hand. Then you take a long breath, lean against him, draw back your other foot and—there you are!"
As Andy spoke John was forced to execute a twist, and found himself sitting on the grass, looking at his companions with such a strange expression that they couldn't help laughing.
"That's how it's done," said Andy, with just a trace of a laugh.
"So—so I see," grunted John, as he arose.
"Oh, rats!" exclaimed Jack. "I thought you were going to do it slow, so we could see the different motions."
"That's the trouble with it," went on Andy. "It has to be done quickly, or it won't work, proving to you that I have nothing up my sleeves," he went on, in the tone of a professional magician; "and that the hand is quicker than the eye. Ahem!"
"Oh, cut it out!" yelled several.
"Yes, show us how it's done. We're all friends of yours," went on Jack. "We may need it in our business when it comes to hazing the Freshmen."
"All right, I'll show you," and with that Andy proceeded to demonstrate slowly, and with much explanation, how the trick fall was brought about. It was really a knack of making the other lad trip himself, by pulling him forward, and then suddenly compelling him to change his center of gravity; and Andy had it down to perfection.
