with a terrible flapping of wings and sudden strange calls resembling
death groans; apes sprang, wild animals rushed through the thickets
around him, bending the saplings and bringing down a rain of leaves, as
though a gale were passing. But it was particularly the serpents that
turned his blood cold when, stepping upon a matting of moving, withered
leaves, he caught sight of their slim heads gliding amidst a horrid maze
