"It's all in fun, you know," explained Andy, as he let fly a snowball at the old janitor, who was always called Shout because he was so deaf.

"Hi there! you stop that!" roared Shout. And then, when they continued to snowball him, he came after them with a wooden snow-shovel.

"Look out! Here comes the enemy!" cried Randy gayly, and let fly a snowball which struck the upraised snow-shovel and sent a shower of loose snow into the janitor's face.

"You young rascals!" roared Plunger, and then lost his footing on some ice. In endeavoring to keep his balance he sent the snow-shovel whirling through the air. It landed at Andy's feet, catching that fun-loving youth in the shins and sending him flat on his face.

"Hurrah! One down!" came from Bob Nixon good-naturedly, and then the chauffeur picked up a large chunk of snow and threw it high in the air, to land directly on Randy's shoulder.

"Great pyramids of Egypt!" gasped Randy. "Is that a snowslide?" For some of the snow had filled his ear and gone down his neck.

"Oh, we didn't begin this, you know," cried the chauffeur gleefully. "Come on, Shout; let's show 'em what the older generation can do." And then he picked up another chunk of snow and hurled it at Andy, nearly burying that youth while he was endeavoring to regain his feet.

"Hi! Hi you!" spluttered Andy. "We went in for snowballing. We didn't go in for avalanches."

"When you start something, always be sure you can finish it," admonished Bob Nixon. And then he picked up a third chunk of snow; but before he could make use of it the Rover twins had dived out of sight around a corner of the school building.

"I guess that's the time we got the worst of it," remarked Andy ruefully.
