"I have heard," said the cuckoo, "that among the places there you would find the country of the little black dogs. You know what sort of creatures those are?"
"Yes, I suppose so," said Griselda, rather reluctantly.
"There are a good many of them in this world, as of course you know," continued the cuckoo. "But up there, they are much worse than here. When a child has made a great pet of one down here, I've heard tell the fairies take him up there when his parents and nurses think he's sleeping quietly in his bed, and make him work hard all night, with his own particular little black dog on his back. And it's so dreadfully heavy—for every time he takes it on his back down here it grows a pound heavier up there—that by morning the child is quite worn out. I dare say you've noticed how haggard and miserable some ill-tempered children get to look—now you'll know the reason."
