“I’m not going to scold him!” laughed Trent, ruffling the dog’s ears. “It’s many a long month since Buff needed a scolding. He didn’t drive the rabbit this way. The rabbit drove itself, before Buff could choose the direction. He——”

“Buff is splendid protection for you, isn’t he?” she broke in, a tinge of nervousness in her soft voice.

“Why, personally, I don’t stand in any great need of protection,” he smiled. “I’m not exactly a timid little flower. But he protects the farm and the house and the livestock as efficiently as a machine-gun company could. He’s a born watchdog.”
