You don't ask a specific question about Nick's character,
so I'll give you the highlights. If you need more information than
what I give you, go to the link below for the details.
This story introduces Nick Adams, a young boy, to life and
death, the birth of a baby and the death of the baby's father.
This is the first "Nick Adams" story by Hemingway. Through this
experience, Nick loses his innocent perspective of life. Even
though he doesn't completely understand the events, he's now been
exposed to the harsh realities of life, something that each of us
Nick is able to see the differences in the ways the Indians
live. The pregnant woman is lying on a wooden bunk in a meager hut.
His father is forced to use a knife to get the baby out, and the
woman must be held down because there is no pain medicine to give
her. The baby is finally born, but while everyone was busy with the
baby's birth, the father of the baby cut his throat. On the trip
back, Nick comes to the conclusion that he will never die.
Even Nick's name is suggestive to the themes in the story. It
refers to Adam, the first man in the Bible, and "old Nick," a name
sometimes used for Satan. Through this young boy, the author refers
to the good and evil that exist in each of us, discovery and loss,
and innocence and experience.
