“No. All the heroes are dead. I don’t want to be a hero. What’s the news from the front?”

“Impossible!” muttered Tom, laughing in spite of himself. Tom had been pondering, wondering, trying to account satisfactorily to himself for this attempt on their lives.

“I have been wondering, thinking about what Mr. Giddings told us at the ‘Lazy J’ ranch,” said Miss Briggs. “You remember what he said about the mysterious Aerial Lake, don’t you?”

“Perhaps not,” returned Elfreda, “but it does go a long way towards proving that there is something in what the foreman of the ‘Lazy J’ told us. I, for one, am in favor of giving that lake a wide berth.”
