Read it through once

One trip a pretty girl of sixteen spent her time in our pilot-house with her uncle and aunt, every day and all day long. I fell in love with her. So did Mr. Thornburg's cub, Tom G----. Tom and I had been bosom friends until this time; but now a coolness began to arise. I told the girl a good many of my river adventures, and made myself out a good deal of a hero; Tom tried to make himself appear to be a hero, too, and succeeded to some extent, but then he always had a way of embroidering. However, virtue is its own reward, so I was a barely perceptible trifle ahead in the contest. About this time something happened which promised handsomely for me: the pilots decided to sound the crossing at the head of 21. This would occur about nine or ten o'clock at night, when the passengers would be still up; it would be Mr. Thornburg's watch, therefore my chief would have to do the sounding. We had a perfect love of a sounding-boat--long, trim, graceful, and as fleet as a greyhound; her thwarts were cushioned; she carried twelve oarsmen; one of the mates was always sent in her to transmit orders to her crew, for ours was a steamer where no end of 'style' was put on.
