McAllister marched over to her, his arm raised threateningly; the girl sat and stared coolly back. For a moment the baffled man stood glaring at her. He would rather have met all the big boys in concerted rebellion than Nancy Caldwell, and felt that he must be fortified within before he could successfully combat her. He stepped up to his desk and clutching a half-empty bottle from it, drained the contents. The tension of the school was immediately relaxed; the pupils nudged each other and giggled and Nancy Caldwell laughed aloud and pulled Scotty out from his hiding place. As everyone expected, McAllister sank into his chair and glared sheepishly about him, making a desperate attempt to retain his dignity. Peter Lauchie stepped out from his post of observation, with a light heart; and strolled off leisurely in search of a weapon. Since the master was now on his way to a better frame of mind, Peter was not the one to retard his happy progress; so he sauntered about, knowing that Roarin' Sandy's Archie would summon him when the time was ripe. His commander did not fail him. With the keen eye of an old campaigner, Roarin' Sandy's Archie saw the moment to strike. The master had worked up a little energy and was again making for Nancy; now was the time to divert his attention; he beckoned to his henchman. As Peter Lauchie entered he showed himself a worthy follower of a worthy leader, for he strode solemnly up the aisle, dragging in his wake a respectably-sized hemlock tree, the branches of which swept up the floor and whipped the boys and girls in the faces, evoking shrieks of laughter. He paused before the master's desk and solemnly handed him the sapling. "Here's the switch to hide Scotty _MacDonald_, sir," he said with great seriousness, and a fine emphasis on the name. The master turned like an animal at bay, and the school broke into a torrent of laughter. He grasped the tree and raised it above his head. "Ah'll batter the cursed impidence out o' ye, ye curse o' a MacDonald!" he roared, making a drive at the boy. But Peter Lauchie knew that the master need not now be taken seriously; he darted down the aisle, McAllister after him, bearing his clumsy weapon, and mowing down all within three yards of his path. The boy leaped over the wood box, dodged round the stove, upset the water pail over the girls and came careering back. Number Nine rose to the occasion; their year of Jubilee, so long delayed, had come at last. The boys joined in the chase, and soon the master became the pursued as well as the pursuer. The girls shrieked and fled to the wall, all except such amazons as Nancy Caldwell and Roarin' Sandy's Teenie, who joined in the race, materially assisting Peter by getting in the master's way or catching hold of his flying coat-tails.
