"Told you so, fellows," declared Matty, smiling; "that's Elmer. He's learning to use the bugle nearly as well as Mark himself."

"Then we're at the end of our trail following, are we?" asked Landy, not without a sigh of relief, for it had not been as easy work in his case as with his less stout comrades.

"Well, pretty near," Matty replied. "We've got to keep it up till we come in sight of the mill."

"But why?" asked George, who seemed to want to know every little thing, so that his natural tendency to object might have a chance to show itself.

"Oh, well, there might be one more opening for a message, and our main business is to translate these, you know."

"Do we stay long at the old mill?" asked Chatz.

Red gave him a quick, suspicious look.

"Aw, I reckon I know what's on our comrade's mind," he remarked, with a wink.

"As what?" demanded Landy.

"Chatz thinks he'd like to prowl around some, and see if that ghost has left any signs. 'Tain't often he's had a chance to meet up with a real haunted house, eh, Chatz?" and Red gave the Southern boy a sly dig in the ribs.
