“Rescue people from the valley? Be in our debt? And he spoke as if he knew us?” fired Jerry at the watchman. “Then it must have been the old hermit, Jackson Bell, whom we rescued—and whose son, Bobby, we saved from the gang of Mexicans. But I can’t understand it—it seems incredible—how came he here—how did he come to mention all this?” and Jerry looked with a puzzled air at Sud Snuffles, who was rapidly recovering.

“He didn’t mention it all at once,” said the watchman. “The old hermit, if that’s what you call him, let out by degrees what I have told you. So his name was Jackson Bell, eh? Well, Noddy didn’t call him anything.”

“Probably he did not want you to remember the name,” suggested Bob. “But I’m sure it’s the same man.” The description of the rescue of the hermit will be found in the book “The Motor Boys Across the Plains; or the Hermit of Lost Lake.”

“What else did you hear, and what happened?” inquired Ned.

“Well, I was naturally surprised to see Noddy and the two persons with him,” resumed the watchman, “and more so when Noddy gave me a note, and said Jerry Hopkins had written it, and that it was permission for him to take out the airship.”

“A note from me?” cried Jerry. “Let’s see it!”

Sud Snuffles fumbled in his pocket, and brought out a crumpled paper, which he extended to Jerry, who eagerly scanned it.

“A rank forgery,” he pronounced it, “yet good enough to fool you, Sud, especially at night.”

“What does the note say?” asked Andy.
