Now was the quiet, fierce solitude of the primeval forest broken by new, strange cries. No longer was there safety for bird or beast. Man had come. Other animals passed up and down the jungle by day and by night — fierce, cruel beasts — but their weaker neighbors only fled from their immediate vicinity to return again when the danger was past.
With man it is different. When he comes many of the larger animals instinctively leave the district entirely, seldom if ever to return; and thus it has always been with the great anthropoids. They flee man as man flees a pestilence.
