"You can only bring him by a charm, and if you are not very careful, he may burst out and kill you."
"Is he so very violent?" said Jobson.
"Very. His breath is scalding hot, and he is a more expensive giant than either my brother or myself."
"Must you pay him, then?" said Jobson's wife.
"He will work without pay, but he needs to be kept hot. He will not work at all unless he is seated right on the top of blazing coals."
"What a funny giant!" said Jobson's little boy. "Does he not burn up?"
"No, the hotter you make the fire the stronger he grows, but when the fire grows cold, all his strength seems to die."
The Jobsons had a long talk over this, and decided that they had better not have anything to do with this strange giant. But once, when they wanted a great deal of heavy stones carried up the hill, they were driven to ask Aquafluens if he would tell them the charm.
"Yes," said he; "it is very simple, but you must not be afraid."
"No," said they, "we will not be afraid."
