And it was late on a Saturday afternoon, when the ladies and the girls had gone to Dexter's Corners to do some shopping, and while the fathers were busy reading and writing, that the events occurred with which the present story opens.

As Dick Rover ran into the farmhouse he heard a slight scream coming from the sitting-room. The scream was followed by exclamations from two men, and then a wild thumping as if someone was hitting the floor with a cane.

"It's a mouse—several of 'em!" came in the voice of Grandfather Rover.

"Oh, my! oh, my! wherever did they come from?" exclaimed old Aunt Martha.

"Never mind where they came from, I'll fix 'em," asserted old Randolph Rover, and then followed another thumping as he rushed around between the chairs and behind the sofa, trying to slaughter some of the scampering mice with his heavy walking stick.

"Where are they? Where are those mice?" demanded Tom Rover, giving a hasty glance around the kitchen.

"There is one—under the sink!" ejaculated his brother Sam, and catching up a stove lifter he let fly with such accurate aim that the unhappy rodent was despatched on the spot.

"I see another one back of the pantry door," said Tom Rover a moment later, and then made a dive into the pantry. Here, in a side closet, the door of which was partly open, he saw a broom and grabbed it quickly. Then he made a wild pass at the mouse, but the rodent eluded him and scrambled over the kitchen floor and into the sitting-room.

"Oh, dear! Oh, dear! Did you ever see so many mice?" came in a wailing voice from Aunt Martha. She had clambered up on a chair and stood there holding her dress tightly around her feet.

"It's another of those boys' tricks, that's what it is," asserted Grandfather Rover. "They ought to be punished for it."
