The dog wagged its stump of a tail, but uttered no sound.

"Is Ned Rutt the worst?" asked Grif.

The dog repeated the performance.

"Is Jim Pizey the worst?" asked Grif.

Milly caught the lad's arm as he put the last question, and looked in the face of the dog as if it were a sibyl about to answer her heart's fear. But the dog wagged its tail, and was silent.

"Thank God!" Milly whispered to herself.

"Is the Tenderhearted Oysterman the worst?" asked Grif.
