Mark Twain

“ Nothing short of perfection will do. That faculty is memory. He cannot stop with merely thinking a thing is so and so; he must know it; for this is eminently one of the 'exact' sciences. With what scorn a pilot was looked upon, in the old times, if he ever ventured to deal in that feeble phrase 'I think,' instead of the vigorous one 'I know!' One cannot easily realize what a tremendous thing it is to know every trivial detail of twelve hundred miles of river and know it with absolute exactness. ”

“ As I started across, the captain glanced aloft at me and said, with a sham uneasiness in his voice--
'Where is Mr. Bixby?'
'Gone below, sir.'
But that did the business for me. My imagination began to construct dangers out of nothing, and they multiplied faster than I could keep the run of them. All at once I imagined I saw shoal water ahead! The wave of coward agony that surged through me then came near dislocating every joint in me. All my confidence in that crossing vanished. I seized the bell-rope; dropped it, ashamed; seized it again; dropped it once more ”

“ Give a man a tolerably fair memory to start with, and piloting will develop it into a very colossus of capability. But ONLY IN THE MATTERS IT IS DAILY DRILLED IN. A time would come when the man's faculties could not help noticing landmarks and soundings, and his memory could not help holding on to them with the grip of a vise; but if you asked that same man at noon what he had had for breakfast, it would be ten chances to one that he could not tell you. Astonishing things can be done with the human memory if you will devote it faithfully to one particular line of business. ”

“ The growth of courage in the pilot-house is steady all the time, but it does not reach a high and satisfactory condition until some time after the young pilot has been 'standing his own watch,' alone and under the staggering weight of all the responsibilities connected with the position. When an apprentice has become pretty thoroughly acquainted with the river, he goes clattering along so fearlessly with his steamboat, night or day, that he presently begins to imagine that it is HIS courage that animates him ”

“ The cry of 'quarter twain' did not really take his mind from his talk, but his trained faculties instantly photographed the bearings, noted the change of depth, and laid up the important details for future reference without requiring any assistance from him in the matter. ”
