It was a vast monster, moving in the waters against the stream and toward the boat.

Its head was raised high, its eyes were inflamed with a baleful light, its jaws, opened wide, bristled with sharp teeth, and it had a long neck joined to a body of enormous bulk, with a tail that lashed all the water into foam.

It was but for an instant that I saw it, and then with a sudden plunge the monster dived, while at the same moment all was as dark as before.
Full of terror and excitement, I loaded my rifle again and waited, listening for a renewal of the noise.

I felt sure that the monster, balked of his prey, would return with redoubled fury, and that I should have to renew the conflict.

I felt that the dangers of the subterranean passage and of the rushing waters had passed away, and that a new peril had arisen from the assault of this monster of the deep.
