"But how did she get here?" asked Garry bewilderedly. "That's what I should like to know," said a grim voice in the doorway. The voice belonged to Mr. Blythe, and the students scattered before his indignant approach. They formed such a comical contrast, the soft-eyed, bewildered cow and the grim, wrathful man as they exchanged look for look, that laughter broke in a wave over the room. Mr. Blythe turned fiercely upon the boys. "This is no laughing matter," he cried. "I am sorry that any student of mine finds it so. It is an outrage and shall be reported at once to the principal." "The cow or the outrage?" Rooster whispered to Garry, but the latter nudged him to be silent. "Old Blythe's on the rampage," he warned. "Better lie low." "Take this animal outside," commanded the teacher irately. "Drive her out! Drive her out! Shoo!" Again laughter assailed the boys. It doubled them up until they were breathless and weak from glee. However, at another stern command from the teacher some of them got behind the animal, some of them before, in an attempt to urge the cow from this unfamiliar stamping ground. But bossy was scared now, and hard to move. Garry finally had an idea. He went out to the campus and returned with a handful of grass. Amid much hilarity he lured the animal inch by inch, step by step toward the front door. The progress was marked by great pomp and ceremony, fully half the students of the school watching it while they howled with laughter. Order was for a time completely suspended and chaos reigned. Arrived at the front door, the cow refused to go further, even for the tempting fodder in Garry's hand. It was necessary, therefore, for some half dozen boys to get behind and push. "Step on the accelerator," cried a wag, and again there was a gleeful outburst. Urged on irresistibly, the reluctant creature finally stepped out into the open. She had scarcely appeared there before a wrathful farmer came rushing up, declaring that he had searched over half of Lenox for his property. He took charge of the cow and led her off. Once more back in their classrooms, the "joke" assumed more serious proportions. With the cow removed, the boys could see that this incident of the animal's appearance in the schoolhouse had probably been conceived and carried out by the same mischief-makers who had ruined Mr. Blythe's map and tampered with the electric fans. "There's bound to be a big row over this," predicted Bill, as he and Garry were selecting the books they would need for the morning period. "Mr. Allen won't let this pass. He'll probably make a thorough investigation, and if he finds the fellows who planted that cow here, I feel sorry for them, that's all." Bill Sherwood was right about the course the principal would take. Mr. Blythe entered an indignant protest at the office, and Mr. Allen promised to discover and punish the offenders if such a thing were possible.
