Harte introduces the men of the camp in a humorous, tongue-in-cheek manner by highlighting the contradictions between their nature or personality and their physical appearances or disabilities. There is a reversal or irony about most of the men. Stumpy, the man chosen to oversee the birth of Cherokee Sal's baby, becomes the midwife of sorts because he has abandoned two families. As a bigamist, he fled to Roaring Camp to avoid legal problems. Many other residents exhibit similar ironies. The man who was the biggest mischief-maker had a "Raphael face," meaning a dignified expression and features. Oakhurst, the gambler, might have been expected to be flamboyant and flashy, but he was as subdued and lost in thought as Hamlet. The bravest man among them was one of the shortest, standing barely more than five feet tall, and he had a soft, shy voice. The strongest man was missing fingers, and the best marksman was one-eyed.
With these contradictions, Harte sets the stage for a story that revolves around religious parody and reversals of tradition. In this story, the "Savior" is named Luck--turning the traditional idea of predestination and an omniscient God on its head. Rather than the child being presented with gifts by the Magi, Luck receives curious contributions that the rag-tag residents drop in a hat. Of course, the Virgin Birth is replaced by birth to a woman who is far from pure. Instead of a chorus of angels announcing the birth, the men fire their pistols in the air.
Harte does his best to reverse every expectation in the story, and he sets up the irony with the way he describes the men of the camp at the beginning of the story.
Paragraph 6 of the story gives details of the characters at the camp:
The assemblage numbered about a hundred men. One or two of these were actual fugitives from justice, some were criminal, and all were reckless. Physically, they exhibited no indication of their past lives and character. The greatest scamp had a Raphael face, with a profusion of blond hair; Oakhurst, a gambler, had the melancholy air and intellectual abstraction of a Hamlet; the coolest and most courageous man was scarcely over five feet in height, with a soft voice and an embarrassed, timid manner. The term “roughs” applied to them was a distinction rather than a definition. Perhaps in the minor details of fingers, toes, ears, etc., the camp may have been deficient, but these slight omissions did not detract from their aggregate force. The strongest man had but three fingers on his right hand; the best shot had but one eye.
There are also some named characters who are introduced at the beginning of the story: Stumpy, the man who adopts the baby (later named Thomas Luck); Kentuck, a "prominent citizen" of the camp; and Cherokee Sal, a "coarse" and "very sinful woman" who is giving birth to baby Luck.
