[This is one of my favorite passages from Mark Twain’s Life On The Mississippi. In it, Twain describes one of the earliest days of his training to become a riverboat pilot at the hands of Horace Bixby, a crack pilot and Twain’s teacher:]
Now and then Mr. Bixby called my attention to certain things. Said he, ‘This is Six-Mile Point.’ I assented. It was pleasant enough information, but I could not see the bearing of it. I was not conscious that it was a matter of any interest to me. Another time he said, ‘This is Nine-Mile Point.’ Later he said, ‘This is Twelve-Mile Point.’ They were all about level with the water’s edge; they all looked about alike to me; they were monotonously unpicturesque. I hoped Mr. Bixby would change the subject. But no; he would crowd up around a point, hugging the shore with affection, and then say: ‘The slack water ends here, abreast this bunch of China-trees; now we cross over.’ So he crossed over. He gave me the wheel once or twice, but I had no luck. I either came near chipping off the edge of a sugar plantation, or I yawed too far from shore, and so dropped back into disgrace again and got abused.
Presently he turned on me and said: ‘What’s the name of the first point above New Orleans?’
I was gratified to be able to answer promptly, and I did. I said I didn’t know.
‘Don’t know?’
This manner jolted me. I was down at the foot again, in a moment. But I had to say just what I had said before.
‘Well, you’re a smart one,’ said Mr. Bixby. ‘What’s the name of the next point?’
Once more I didn’t know.
‘Well, this beats anything. Tell me the name of any point or place I told you.’
I studied a while and decided that I couldn’t.
‘Look here! What do you start out from, above Twelve-Mile Point, to cross over?’
‘I — I — don’t know.’
‘You — you — don’t know?’ mimicking my drawling manner of speech. ‘What do you know?’
‘I — I — nothing, for certain.’
‘By the great Caesar’s ghost, I believe you! You’re the stupidest dunderhead I ever saw or ever heard of, so help me Moses! The idea of you being a pilot — you! Why, you don’t know enough to pilot a cow down a lane.’
Oh, but his wrath was up! He was a nervous man, and he shuffled from one side of his wheel to the other as if the floor was hot. He would boil a while to himself, and then overflow and scald me again.
‘Look here! What do you suppose I told you the names of those points for?’
I tremblingly considered a moment, and then the devil of temptation provoked me to say: ‘Well—to—to—be entertaining, I thought.’
This was a red rag to the bull. He raged and stormed so (he was crossing the river at the time) that I judge it made him blind, because he ran over the steering-oar of a trading-scow. Of course the traders sent up a volley of red-hot profanity. Never was a man so grateful as Mr. Bixby was: because he was brim full, and here were subjects who would talk back. He threw open a window, thrust his head out, and such an irruption followed as I never had heard before. The fainter and farther away the scowmen’s curses drifted, the higher Mr. Bixby lifted his voice and the weightier his adjectives grew. When he closed the window he was empty. You could have drawn a seine through his system and not caught curses enough to disturb your mother with.
