"She ought to be spanked," he confided to Winnie, "but I don't believe in that form of punishment for children as old as she is."

"It wouldn't do any good," said Winnie, "your mother spanked her years ago when she'd take these silent fits. It only made her more obstinate. You can do more with Sarah, Hughie, by helping her out of a tight place than any way I know. She's always getting into trouble and she never forgets the ones that stand by her. You keep your eyes open and the chance will come."

The opportunity came sooner than either of them expected. For nearly a week Jack Welles had been storming, to any one who would listen to him, about the "low-down" thief who nightly took his can of fishing worms.

"Plumb lazy, I call it," grumbled Jack, "to cart away the worms a fellow breaks his back digging. Some worthless tramp is catching fish with my worms and I intend to catch him."

His wails had reached the ears of Doctor Hugh, himself an ardent fisherman when time permitted and his sympathies were entirely with the defrauded one.

"Sit up some night and watch," he advised the lad. "Put the can in the usual place—where do you keep it—on the back step?—all right, put it there, and then hide back of the willow tree. You say it is done sometime between ten and twelve, for you go to bed at ten and your father comes home at midnight and finds the can empty? That ought to make it easy for you, for you know when to watch for the thief."

Jack's father was engaged in some delicate electrical experiments that were conducted in his factory at night to escape the vibration caused by the heavy machines.

Coming home from the Jordan office a little after then the next night after he had given Jack his advice, Doctor Hugh remembered what he had said and wondered if the boy had been successful in detecting the thief. As he neared the Welles house he heard loud and angry voices.
