What is the main character of "An Occurrence at Owl Creek Bridge," Peyton Farquhar's, occupation?

The opening words of Part II of "An Occurrence at Owl
Creek Bridge" tell exactly what Peyton Farquhar's occupation
was.

Peyton
Farquhar was a well to do planter, of an old and highly respected Alabama family. Being
a slave owner and like other slave owners a politician, he was naturally an original
secessionist and ardently devoted to the Southern
cause.

He owned a big tract
of land which had been passed down to him by his forebears. He undoubted planted cotton
and used black slaves to do all the work. There were many such plantation owners in the
South, and they enjoyed prosperity because they did not have to pay for the heavy labor
involved in growing, tending, and picking cotton. The cotton was baled and shipped to
the textile mills in England. It was the slave owners of the South, of course, who were
most strongly opposed to the growing anti-slavery movement in the north. The rich
plantation owners not only thought that slavery was a benign institution but were bent
on spreading it farther and farther to the west. 

Peyton
Farquhar's occupation was restricted to managing a big plantation. He was following in
the footsteps of his ancestors who had been slave holders for
generations.
