inclined to torment the boys by tying knots in their clothes when they
went swimming, or by throwing mud at them when they wanted to come out,
and they had no deep love for him. But somewhere in Ben Blankenship
there was a fine generous strain of humanity that provided Mark Twain
with that immortal episode in the story of Huck Finn--in sheltering the
Nigger Jim.

This is the real story:

A slave ran off from Monroe County, Missouri, and got across the river
into Illinois. Ben used to fish and hunt over there in the swamps, and
one day found him. It was considered a most worthy act in those days to
return a runaway slave; in fact, it was a crime not to do it. Besides,
there was for this one a reward of fifty dollars, a fortune to ragged
outcast Ben Blankenship. That money and the honor he could acquire must
have been tempting to the waif, but it did not outweigh his human
sympathy. Instead of giving him up and claiming the reward, Ben kept the
runaway over there in the marshes all summer. The negro would fish and
Ben would carry him scraps of other food. Then, by and by, it leaked
out. Some wood-choppers went on a hunt for the fugitive, and chased him
to what was called "Bird Slough." There trying to cross a drift he was
drowned.

In the book, the author makes Huck's struggle a psychological one between
conscience and the law, on one side, and sympathy on the other. With Ben
Blankenship the struggle--if there was a struggle--was probably between
sympathy and cupidity. He would care very little for conscience and
still less for law. His sympathy with the runaway, however, would be
large and elemental, and it must have been very large to offset the lure
of that reward.
