"Where does he live?"

"In the big white house on the hill, opposite the depot."

"I know the place," put in Songbird.

"We'll go there," said Sam. "Much obliged," he added, to the man.

"Maybe Tom went there and that is how Lambert came to see him near the freight house," suggested Songbird.

"We'll soon know," returned the youngest Rover.

It did not take the students long to cross the railroad tracks and reach Doctor Slate's residence. They found the old doctor out in his garden, tying up some bushes. He was a white-haired gentleman and had given up his regular practice some years before.

"No, there has been no young man to see me," he said, in answer to Sam's question. "Old Mrs. Powers was in, and Pop Slocum, the negro, and that's all."

"In that case, Tom must be hanging around town, waiting for Doctor Havens to return," said Songbird.

"It's a puzzle to me," said Sam, with a deep sigh, and he and his chum walked slowly away.
