"What do you know about this? Professor Lemm is keeping goats in his room!" cried Jack.

These and a score of other cries rent the air, while all the cadets crowded into the doorway of the room to see what was going on. In the bunch of boys were Slugger Brown and Nappy Martell, and it must be confessed that these two unworthies were enjoying the scene quite as much as anybody.

"I'll fix some of you for this!" roared Asa Lemm, as he struggled to his feet, slipping around and clutching the end of his bed as he did so. "I'll have some of you suspended! Where is Colonel Colby? Send for Colonel Colby at once!"

Evidently Patrick, the larger goat, did not like the looks of the irate teacher, who was now shaking his fists at the grinning cadets. Suddenly the goat made another leap, this time striking Asa Lemm in the shoulder, and once more the professor went down, this time with his feet sliding directly under the bed, so that he became somewhat wedged in from his waist down. Then the goat made another leap and charged toward the door to the hallway.

"Look out!" warned Jack, and was just in time to push Fred out of danger. Then the goat made a rush, and the next minute came full tilt into Slugger Brown, sending the bully crashing into those behind him. The second goat also leaped from the bed, and made for the doorway, hitting Martell as he passed.

"Look out for the battering-ram!"

"This is only a battering goat—but it's just as bad!" yelled Andy. "Go it, goat! Go it!" he added gleefully.

Both goats did "go it." They raced through the hallway, knocking down cadets right and left. One younger boy, named Stowell, but who was always called Codfish by the others because of his unusually broad mouth, was attacked at the head of the stairs and sent hurtling down to the bottom.

"Oh! oh! I'm killed! He has knocked me to pieces!" yelled Codfish.

With the two goats racing around the school, the excitement increased. But gradually the goats were driven by the Rovers to a lower hallway, and then toward a side door, which Jack and Fred lost no time in opening.
