What metaphors are used in The Underdogs a Novel of the Mexican Revolution by Mariano Azuela?

Azuela writes in a modern style; several parallels can be drawn to American author Ernest Hemingway. Like Hemingway, Azuela employs a clipped, laconic style, with the narrative being "the tip of an iceberg," only hinting at deeper things left unstated. Appropriately then, devices like metaphors and similes are largely absent, in favor of an unadorned, straight-ahead style.
