“Why thot?” he asked, puzzled.

“Becos,” the Master answered, “'im as did this killed for blood—and for blood only. If had bin ony other dog—greyhound, bull, tarrier, or even a young sheep-dog—d'yo' think he'd ha' stopped wi' the one? Not he; he'd ha' gone through 'em, and be runnin' 'em as like as not yet, nippin' 'em, pullin' 'em down, till he'd maybe killed the half. But 'im as did this killed for blood, I say. He got it—killed just the one, and nary touched the others, d'yo 'see, Jim?”

The postman whistled, long and low.

“It's just what owd Wrottesley'd tell on,” he said. “I never nob'but half believed him then—I do now though. D'yo' mind what th' owd lad'd tell, Master?”

James Moore nodded.

“Thot's it. I've never seen the like afore myself, but I've heard ma grandad speak o't mony's the time. An owd dog'll git the cravin' for sheep's blood on him, just the same as a mon does for the drink; he creeps oot o' nights, gallops afar, hunts his sheep, downs 'er, and satisfies the cravin'. And he nary kills but the one, they say, for he knows the value o' sheep same as you and me. He has his gallop, quenches the thirst, and then he's for home, maybe a score mile away, and no one the wiser i' th' mornin'. And so on, till he cooms to a bloody death, the murderin' traitor.”

“If he does!” said Jim.

“And he does, they say, nigh always. For he gets bolder and bolder wi' not bein' caught, until one fine night a bullet lets light into him. And some mon gets knocked nigh endways when they bring his best tyke home i' th' mornin', dead, wi' the sheep's wool yet stickin' in his mouth.”

The postman whistled again.

“It's what owd Wrottesley'd tell on to a tick. And he'd say, if ye mind, Master, as hoo the dog'd niver kill his master's sheep—kind o' conscience-like.”
