"What was it, Bart?"

Laying down his lunch, Bart drew out of a package a chronometer.

"Found that in the shed?" asked the surprised father.

"Yes, on a shelf."

"Why, Bart, this has got the letters of our lighthouse on it. Must have come from here. And in our shed! How did it get there? I must show this to Dave," said Thomas Trafton.

"Hush-sh!" exclaimed Dave, when his assistant entered the room; "Toby is trying to get some sleep."

"See here!" said Thomas, in low tones. "Must show you something."

"I never saw it before," replied Dave, handling the chronometer. "It belongs here, though. There are the initials. Where did you get it?"

A stir among the bedclothes arrested the attention of the two men. Toby Tolman had opened his eyes, and was looking at them. Something he saw must have pleased him, for he smiled.

"That is right, Dave. I am glad you brought it back. I would put it up."
