And the old man said, "Here are the very beans themselves!" He went on pulling out of his pocket a number of strange looking beans. “As you are so sharp,” says he, “I don’t mind doing a swop with you–your cow for these beans.”
“Walker!” says Jack; “wouldn’t you like it?”
“Ah! you don’t know what these beans are,” said the man; “if you plant them over-night, by morning they grow right up to the sky!”
