Which literary devices does the author use in these lines from a naturalistic story? Besides, the art of burning to bedrock still lay in the womb of the future, and the men of Forty-Mile, shut in by the long Arctic winter, grew high-stomached with overeating and enforced idleness, and became as irritable as do the bees in the fall of the year when the hives are overstocked with honey.
(from "The White Silence" by Jack London)
