“No, it is not thunder,” said Cruncher. “The captain is loading the boat with coal. Don’t be afraid.”

“I’m not afraid,” said Lightfoot. “Only coal is very black and dirty stuff.”

“Yes, it is,” agreed Nibbler. “But it may be a good thing for you, Lightfoot.”

“How?” asked the goat.

“In this way,” said Nibbler. “I have seen this boat loaded with coal before. They fill the hold as full as they can, and they don’t put the covers on.”

“But if they fill it full,” said Lightfoot, “they will cover me with the coal, and then how can I get out?”

“I’ll tell you,” answered Nibbler. “They will not fill all the boat at once. It takes about two days. And when half the boat is full the coal is in a pile in the middle, like a hill. You can climb up the side of the coal-hill, Lightfoot, and then you will be out of the hold. You can scramble up on top of our stable-cabin and from there you can easily jump to shore.”

“Oh, that will be fine!” cried the goat.

“Do you think you can walk up the hill of coal in this boat?” asked Cruncher.
