oars, and he stepped to the edge of the dock and untied one of the boats and leaped in.
"I must find them!" they heard the youth mutter to himself. "I must find them and bring them back!"
"Did you hear that?" asked Roger. "What is he talking about?"
"That remains to be found out. Come, let us follow him," returned Dave.
They procured two pairs of oars, and were soon in another boat and pulling behind Shadow Hamilton. The boy who was asleep seemed to possess supernatural strength, and they had no easy time of it keeping up with him. His course was up the Leming River, past Robbin's Point, and then into a side stream that was rather narrow, but almost straight for a distance of two miles.
"Do you know where this stream leads to?" questioned Roger.
"I do not."
"Almost to the old castle that we visited last winter on our skates, the day we caught that robber and saved Billy Dill. The river makes half a dozen twists and turns before the castle is reached, but this is a direct route and much shorter."
"Can it be possible that Shadow is going to the old castle?" queried the country boy.
"I'm sure I don't know. We'll learn pretty soon."
