The men-- numbering around a hundred-- dwelling in Roaring Camp's cabin are described as reckless fugitive types that most of us today would describe as homeless people with unattractive features. As it says in the text, "The strongest man had but three fingers on his right hand; the best shot had but one eye" (pg. 12). The importance of the description of the men lies in their character. The gritty picture Harte puts in our mind almost might disgust some people, especially after they read how they treat the only woman in Roaring Camp, "Cherokee Sal."
I disagree with the name of the story "The Luck of Roaring Camp," however. With the arrival of the infant baby later known as Luck, all of the men begin to change. All of the men begin to find a sense of meaning in their life during the time Luck was with them, and things begin to improve and thrive in Roaring Camp-- so they call the baby "Luck" as if the infant was their lucky charm like Oakhurst declared he was. The baby wasn't a good luck charm, though. The baby was a gift from above to give the men inspiration and purpose in their lives.
While the name of the child might have been created for lack of a better name anyone else could think of, I don't think the child brought any luck, it just brought a spark of meaning and importance in their lives. Things in Roaring Camp only got better because the men wanted everything to be perfect for Luck. The reason for this is they all felt like a father to him. They all wanted to spend time with the baby and all wanted the best things in the world for the baby.
As the narrator tells us about the daily lives of the men, "Almost imperceptibly a change came over the settlement... The cabin assigned to 'Tommy' Luck first showed signs of improvement. It was kept scrupulously clean and whitewashed... The men who were in the habit of lounging at Stumpy's to see how the Luck got on seemed to appreciate the change" (21-22).
The men even stopped their everyday boyish behavior by watching their language and remaining more quiet to bring a peaceful atmosphere for Luck. Towards the end of the story, I began to think the men were beginning to worship Luck as some kind of idol. When Kentuck died, he became happy to know he was dying with the baby when he said "He (Luck) is taking me with him. Tell the boys I've got luck with me now" (29). Kentuck made it sound like he was selected by the chosen one to accompany him into the next world!
The point of all of this shows that an infant or child coming into a world of men with nothing left to appreciate in their lives in turn gives them all something to live for as most fathers do for their own children. I really think that while sometimes in life I kind of go through the motions with a lack of purpose, I know if I ever get to become a father I won't rest until the child has everything better I didn't have.
