Lightfoot, the Leaping Goat: His Many Adventures by Richard Barnum

Lightfoot stamped his hoofs on the hard rocks, shook his horns, wiggled the little bunch of whiskers that hung beneath his chin, and called to another goat who was not far away:
“I’m going up on the high rocks!”
“Oh, you’d better not,” said Blackie. “If you go up there you may slip and fall down here and hurt yourself, or some of the big goats may chase you back.”
“Well, if they do I’ll just jump down again,” went on Lightfoot, as he stood on his hind legs.
“You can’t jump that far,” said Blackie, looking up toward the high rocks which were far above the heads of herself and Lightfoot.
