"Firemen have to slide on ropes!" Freddie spoke up, recovering himself, "and I'm going to be a fireman. I was one that time, because I tried to save somebody and didn't care if I got hurted!"

"You are a brave little boy," Aunt Sarah assured him. "You just sit here with sister while I try to get that naughty Frisky before she spoils the garden."

By this time the calf was almost lost to them, as she plunged in and out of the pretty hedges. Fortunately Bert and Harry just turned in the gate.

"Runaway calf! Runaway calf!" called the boys. "Stop the runaway!" and instantly a half-dozen other boys appeared, and all started in pursuit.

But Frisky knew how to run, besides she had the advantage of a good start, and now she just dashed along as if the affair was the biggest joke of her life.

"The river! The river!" called the boys

"She'll jump in!" and indeed the pretty Meadow Brook, or river, that ran along some feet lower than the Bobbseys' house, on the other side of the highway, was now dangerously near the runaway calf.

There was a heavy thicket a few feet further up, and as the boys squeezed in and out of the bushes Frisky plunged into this piece of wood.

"Oh, she's gone now, sure!" called Harry "Listen!"

Sure enough there was a splash!
