"Mercy! What's that?" screamed Mrs. Bobbsey, turning pale.

Mr. Bobbsey made a rush for the kitchen. Nan and Bert, with Flossie, gathered about their mother. Then they heard Dinah calling:

"Stop it, Freddie! Stop it I done tell you! Does yo'-all want me t' git soaked? An' yo'-all will suah spoil them pancakes! Oh, now yo' hab done it! Yo' squirted right in mah mouf! Oh mah goodness sakes alive!"

Mrs. Bobbsey looked relieved.

"Freddie must be up to some prank," she said.

"Freddie, stop it!" commanded Mr. Bobbsey, and then he was heard to laugh. The others all went out to the kitchen and there they saw a curious sight.

Freddie, with his new toy fire engine, was pumping water on fat Dinah, who was laughing so heartily that she could do nothing to stop him. Mr. Bobbsey, too, was shouting with mirth, for the hose from the toy engine was rather small, and threw only a thin, fine spray.

"I'm a fireman!" cried Freddie, "and I'm pretending Dinah is on fire. See her red apron—that's the fire!" and the little fellow turned the crank of his engine harder than ever, throwing the tiny stream of water all over the kitchen.

"That's enough, Freddie," said Mr. Bobbsey, when he could stop laughing. Dinah was still shaking with mirth, and Freddie, looking in the tank of the engine, said:

"There's only a little more water left. Can't I squirt that?"
