Read it through once

For a long time wages had been two hundred and fifty dollars a month; but curiously enough, as steamboats multiplied and business increased, the wages began to fall little by little. It was easy to discover the reason of this. Too many pilots were being 'made.' It was nice to have a 'cub,' a steersman, to do all the hard work for a couple of years, gratis, while his master sat on a high bench and smoked; all pilots and captains had sons or nephews who wanted to be pilots. By and by it came to pass that nearly every pilot on the river had a steersman. When a steersman had made an amount of progress that was satisfactory to any two pilots in the trade, they could get a pilot's license for him by signing an application directed to the United States Inspector. Nothing further was needed; usually no questions were asked, no proofs of capacity required.
