CHAPTER XXVI
THE SPRING TRAP
For several moments the boys gazed in silence at the strange marks they had come across. Then Jack said:
“Well, fellows, we seem to be up against some more of that mystery.”
“Why?” asked Bony. “Do you think this has anything to do with the other?”
“I do.”
“You mean the strange sound we heard at night?” asked Will.
“That’s it,” went on Jack. “I think we are on the track of something queer.”
“And do you intend to look further?” was Nat’s query.
“Well, not to-day,” answered Jack. “But I will sooner or later. I believe something happened here which has to do with that queer disturbance we have heard several times. What it is I don’t know, but I’m going to find out.”
