Zane Grey,
The Last Trail — Chapter 13
(1909)
“ Far away among the somber trees, where the shade deepened into impenetrable gloom, lay a menace, invisible and indefinable.A wind, a breath, a chill, terribly potent, seemed to pass over the borderman. Long experience had given him intuition of danger.As he moved slightly, with lynx-eyes fixed on the grove before him, a sharp, clear, perfect bird-note broke the ominous quiet. It was like the melancholy cry of an oriole, short, deep, suggestive of lonely forest dells. By a slight variation in the short call, Jonathan recognized it as a signal from Wetzel. ”
