"Abner Peck saw your dog and Ventnor's running together through my sheep pasture at sundown on Tuesday evening," answered old Paul. "Wednesday morning I found this in the corner of the pasture where the sheep were worried. Your uncle admits that it was tied around your dog's neck on Tuesday."

And old Paul held out triumphantly a faded red ribbon. Curtis recognized it at a glance. It was the ribbon his little cousin, Lena, had tied around Don's neck Tuesday afternoon. He remembered how they had laughed at the effect of that frivolous red collar and bow on Don's massive body.

"I'm sure Don isn't guilty!" he cried passionately.

Mr. Locksley shook his head.

"I'm afraid he is, Curtis. The case looks very black against him, and sheep-stealing is a serious offence."

"The dog must be shot," said old Paul decidedly. "I leave the matter in your hands, Mr. Locksley. I've got enough proof to convict the dog and, if you don't have him killed, I'll make you pay for the sheep he worried."

As old Paul strode away, Curtis looked beseechingly at his uncle.

"Don mustn't be shot, Uncle!" he said desperately. "I'll chain him up all the time."

"And have him howling night and day as if we had a brood of banshees about the place?" said Mr. Locksley sarcastically. He was a stern man with little sentiment in his nature and no understanding whatever of Curtis's affection for Don. The Bayside people said that Arnold Locksley had always been very severe with his nephew. "No, no, Curtis, you must look at the matter sensibly. The dog is a nuisance and must be shot. You can't keep him shut up forever, and, if he has once learned the trick of sheep-worrying, he will never forget it. You can get another dog if you must have one. I'll get Charles Pippey to come and shoot Don tomorrow. No sulking now, Curtis. You are too big a boy for that. Tie the dog up for the night and then go and put the calves in. There is a storm coming. The wind is blowing hard from the northeast now."

His uncle walked away, leaving the boy white and miserable in the yard. He looked at Don, who sat on his haunches and returned his gaze frankly and open-heartedly. He did not look like a guilty dog. Could it be possible that he had really worried those sheep?
