Read it through once

The moment that the boat was under way in the river, she was under the sole and unquestioned control of the pilot. He could do with her exactly as he pleased, run her when and whither he chose, and tie her up to the bank whenever his judgment said that that course was best. His movements were entirely free; he consulted no one, he received commands from nobody, he promptly resented even the merest suggestions. Indeed, the law of the United States forbade him to listen to commands or suggestions, rightly considering that the pilot necessarily knew better how to handle the boat than anybody could tell him. So here was the novelty of a king without a keeper, an absolute monarch who was absolute in sober truth and not by a fiction of words. I have seen a boy of eighteen taking a great steamer serenely into what seemed almost certain destruction, and the aged captain standing mutely by, filled with apprehension but powerless to interfere. His interference, in that particular instance, might have been an excellent thing, but to permit it would have been to establish a most pernicious precedent. It will easily be guessed, considering the pilot's boundless authority, that he was a great personage in the old steamboating days. He was treated with marked courtesy by the captain and with marked deference by all the officers and servants; and this deferential spirit was quickly communicated to the passengers, too. I think pilots were about the only people I ever knew who failed to show, in some degree, embarrassment in the presence of traveling foreign princes. But then, people in one's own grade of life are not usually embarrassing objects.
