“That’s the idea! We know more to start with than any one else, and we ought to be able to find something, provided there is anything to be found,” Lanky put in.

“A lot of time has passed,” interposed Frank. “I am not opposed to the idea, but I am fearful that we won’t find anything that will be of benefit.”

“It certainly would be too late to hunt for any tracks of automobiles or anything of that kind,” said Buster. “Even if we had a chance this morning, the rain has spoiled whatever chance remained.”

“It doesn’t seem to me that hunting for automobile tracks would help us, anyhow,” said Frank. “I don’t think the automobile had very much to do with it.”

“It took those men away, didn’t it?” asked Ralph.

Frank smiled quietly. That question had been asked before, as also the other one—where was the automobile when Mrs. Parsons came into the house?

It was agreed at once that all the boys should be down at the boat-house at ten o’clock, and Lanky was given the job of seeing that oil and gas were aboard, and Buster’s job was to have lunch for all on board, inasmuch as they would spend the day up the river.

Minnie joined the group of boys after a short while.

“I am having a little lawn party at the house to-morrow afternoon in honor of Mr. Cunningham,” she said. “Won’t you boys be there?”
