"Whoop!" cried Bunny. "That's great!"

"I wouldn't whoop," observed Sue, shaking her finger at her brother.

"Why not?" he asked.

"Because this isn't a bonfire. Somebody's shed is burning up; and though it looks nice it isn't any fun for them. We ought to be sorry."

"Well I am," said Bunny. "I'm sorry for them, but I'm glad for myself that I'm going to see the fire. Is that all right, Momsie?"

"I guess so," answered Mrs. Brown, and then she hurried on to the fire with the children, while Uncle Tad raced ahead with the red fire-cracker extinguishers.

Over the fields, from other farmhouses, people came running. Men and women, and boys and girls. They, also, wanted to see the fire. As Bunny and Sue, with their mother, hurried on they saw that the blaze was in a low shed, and from this shed came wild squeals.

"They sound like pigs!" said Bunny.

"I guess it is the pig-pen on fire," replied Mother Brown.

Bunny and his sister, with their mother, were at the fire almost as soon as Daddy Brown and Uncle Tad. Then they saw for sure that what was blazing was a big pig-pen built on the side of a barn. The barn had not yet caught fire.
