From a field, not far away, came a noise that sounded like:

“Boo! Boo! Boo!”

“Bow wow!” barked Don.

“Yes, that’s the bull all right,” said Bob. “But we’ll drive him back in the lot where he belongs, won’t we, Don, old fellow?”

“Bow wow!” barked Don again. I suppose he was saying: “Yes, yes! Of course we will!”

Don knew nothing about bad black bulls, and Bob was not a very big boy. Still he was brave, and so was Don.

“Come on, old fellow!” called Bob to the dog.

“Bow wow!” barked Don. “I’m coming!”

“Oh dear!” cried Sallie. She couldn’t help being just a little bit afraid. Girls are made that way on purpose, so boys and dogs can protect them.
