"I'll bet that Tim Roon threw it!" stormed Meg. "You wait!"

Meg was very quick to think and to act, and the sight of her favorite
brother, one blue eye almost closed, roused her to strong measures.

"Come on, and rush 'em!" she cried, her little arms waving like
windmills. "Don't stand here, throwing balls. Let's capture their old
fort!"

For an instant they stared at her, and then, the idea appealing, the
whole Black army poured over the side of the fort, and charged on the
enemy, shrieking wildly. Bobby, who could barely see where he was
going, was swept along with the rest.

Upstairs in the schoolhouse, the teachers looked at each other in
surprise, and Mr. Carter was equally astonished.

"Surrender!" shouted Meg, the first to leap the wall of the Orange fort.

The Orange army simply backed. It was very funny to see them. They
had not expected an open attack, and they were too taken by surprise to
guard their piles of ammunition. As the opposing forces climbed their
wall they dumbly gave way and moved back, back, till, with a cry of
joy, the Black fighters swooped upon the orderly mounds of snowballs.
With their ammunition gone, of course the Oranges could do nothing less
than give in.

Mr. Carter came up laughing.
