"Well," resumed Dutch, "some of us have rigged up an effigy, in the shape of a student in a dress suit, and at this moment the said imitation student is strung on this wire, which extends from your window across the campus, to the clump of elms just beyond Booker Memorial chapel. The effigy is a sort of trolley car, and this is the wire. This cord, which I just hauled up is also attached to the figure. Now at the proper time, when Proc. Zane goes out to catch some poor chap, who has been off to see his best girl, and has stayed too late, I'll pull this string, the figure will slide along the wire, with the feet just touching the ground, and the proctor thinking it is a student, will rush up to identify him. There will be something interesting when the two meet," and Dutch began to chuckle. "But how can we see it?" asked Tom. "It's as dark as a pocket to-night." "All the better. The fellows hidden in the clump of elms have an automobile search light, which they will turn on at the proper moment. Do you catch on?" "Wow! It's rich!" cried Phil. "All to the mustard and the spoon, too!" decided Tom. "A lallapaloosa!" was Sid's comment. "And not a bit of danger," added Dutch. "As soon as the search light flashes on the scene, and the proctor is made aware of the joke, I'll cut the wire from your window, it will fall to the ground, be hauled in by the fellows in the elms, together with the figure, and not a bit of evidence will remain." "Great!" commented Tom. "But how can you be sure that the proctor will be out there?" "Oh, we've arranged for that. Snail and Holly took pains to converse, rather loudly, in Mr. Zane's hearing to-night, though they pretended not to see him. They intimated that they might try to sneak in about eleven o'clock." "Then the trick comes off then?" asked Phil. "Exactly. We've got half an hour yet." The students sat and talked of many things while waiting, chiefly baseball, until a slight vibration of the wire and a tug of the cord warned them that the time for action had arrived. Dutch explained that he had arranged a code of signals with his chums so that he knew when to haul in on the cord which would pull the stuffed figure along the wire. "There it goes!" he whispered finally. "Now watch the fun!" He began to haul, and the sagging of the wire told of a weight on it. Listening, as they peered from the window into the darkness, Tom and his friends could hear some one running across the campus. Then came a challenge. "Stop, if you please, sir! I see you, and it is useless to try and sneak into college at this hour! I demand your name, sir!" "That's Zane!" whispered Phil. A moment later the wire was violently agitated. "He's caught him!" exclaimed Dutch. "Why don't they turn on the light, so he can see it's only a stuffed scarecrow?"
