Of course Giraffe was indignant.

"Why, I could beat Bumpus with one hand tied behind me!" he declared.

"Oh! you don't say so?" mocked Step-hen, who for some reason seemed desirous of arousing the feeling of rivalry between these two scouts, and egged them on as a boy who loved to see dogs fight, would sick one on the other.
