"Because the current is swifter in the middle of the stream than near the banks, for the friction of the shore has some effect on its flow."
"That is bringing it down to a fine point," said Captain Cayo, laughing, for he was entirely unused to river navigation.
I kept the Sylvania as near the shore as I deemed it prudent to go, while the Islander went in the middle of the river, as if her captain desired to avoid falling into any possible trap. The wind was southerly and quite fresh. I directed the mate to shake out the fore squaresail and the fore topsail. In twenty minutes, by the clock in the pilot-house, we were abreast of the Islander, but half a mile from her, for she was still in the middle of the river. By this time, Captain Blastblow evidently saw his mistake in not setting his squaresails, for the wind was blowing about half a gale.
I put the helm about a half a point nearer to the course of the other steamer. I immediately noticed that her pilot made a corresponding change in her helm. Moses kept an eye on her, and understood the game perfectly. I did not attempt to run any closer to her, for a turn in the river would soon bring the Sylvania alongside of her. If the vessel attempted to go any nearer the shore, she would have to stand out again in order to pass the bend above. In a word, the Islander was cornered.
Captain Blastblow could not help realizing the situation of the steamer he sailed. Too late he sent his men aloft to loose the squaresail. Before they could get the gasket off, I had to port the helm to prevent striking the other steamer. All our hands were in position to do the parts before assigned to them.
I kept a sharp watch upon the actions of the Islander to meet any change in her course. I saw Captain Blastblow in the pilot-house at the wheel. He looked very nervous and disturbed, and I did not wonder at it.
"Sheer off, or you will be afoul of us!" shouted the captain of the runaway steamer.
"Sheer off, or you will be afoul of us!"

At the same moment he rang his gong to stop her. I rang mine also the moment I heard the other. Moses was standing by his lever and wheel, and I think the Sylvania was stopped before the Islander. Of course we continued to go ahead under the impulse of the momentum given the two boats.
