Impetuous by nature, he made a dive in the direction indicated, only speedily to come to grief; for he tripped over some hair cushions that may have been purposely thrown into the aisle, and measured his length on the floor.

Paul had himself discovered a moving figure over in the quarter mentioned. There could not be the slightest doubt about it being a boy, he believed, and in the hope of at least getting near enough to recognize the interloper, he hastened forward as fast as policy would permit.

With that lamp in his hand he did not want to follow the sad example of Bobolink for such an accident might result in setting fire to the building.

Now the figure began to put on more speed. Evidently the escaping party believed there was considerable danger of his being caught; and

could guess what must follow if he fell into the hands of the aroused scouts.

Just in time did Paul discover that a piece of clothes line, probably taken from a yard close by, had been cleverly fastened across the aisle about six inches from the floor. It was undoubtedly intended to trip any who unguardedly came along that way.

"'Ware the rope, fellows!" he called back over his shoulder; for some of his comrades were pushing hotly after him.

The warning came too late, for there was a crash as one scout made a dive; and from the various cries that immediately arose Paul judged that the balance of the detail had swarmed upon the fallen leader, just as though they had the pigskin oval down on the football field.

By now the escaping figure had reached the open window through which he must have entered some time previously, taking time to lay these various traps by means of which he expected to baffle pursuit.

Paul believed that such an ingenious artifice could have originated in no brain save that of Ted Slavin, or possibly his crony, Ward Kenwood. Hence he was trying his best to discover something familiar about the figure now clambering up over the windowsill.
