"Look out, Carlo! Look out!" cried Mirabell. "Be careful or you'll break my Lamb's string!"
But Carlo was not careful. He did not mean to make trouble, but he did. He barked and growled and jumped around until his legs were all tangled up in the cord.
"Oh, look!" suddenly cried Arnold. "Look at your Lamb!"
And, as he spoke, Carlo gave a big jump to get the tangling string off his legs. The string broke, but, as it did so, the Lamb started to roll toward the open coal hole. And, at the same moment, the driver of the wagon began shoveling some of the black lumps down the opening.
"Oh! Oh! Oh!" cried Mirabell.
And then the white, woolly Lamb on Wheels rolled across the sidewalk, and disappeared down into the dark coal hole!
CHAPTER VII
THE LAMB CARRIED AWAY
Mirabell and Arnold were so surprised for a moment at what had happened that they could only stand, looking at the hole in the sidewalk down which the Lamb on Wheels had fallen. Carlo, the fuzzy little dog, seemed to know he had done something wrong in getting tangled in the string, breaking it off, and so sending the Lamb wheeling along until she slid into the coal hole. And the dog gave a howl and ran back toward the house, having finally managed to get his legs loose from the cord.
"Bow-wow!" barked Carlo, as he ran.
