Read it through once

The owners and captains were the only obstruction that lay between the association and absolute power; and at last this one was removed. Incredible as it may seem, the owners and captains deliberately did it themselves. When the pilots' association announced, months beforehand, that on the first day of September, 1861, wages would be advanced to five hundred dollars per month, the owners and captains instantly put freights up a few cents, and explained to the farmers along the river the necessity of it, by calling their attention to the burdensome rate of wages about to be established. It was a rather slender argument, but the farmers did not seem to detect it. It looked reasonable to them that to add five cents freight on a bushel of corn was justifiable under the circumstances, overlooking the fact that this advance on a cargo of forty thousand sacks was a good deal more than necessary to cover the new wages.
