But you could if your memory had been patiently and laboriously trained to do that sort of thing mechanically.
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.
At the time that wages soared so high on the Missouri River, my chief, Mr. Bixby, went up there and learned more than a thousand miles of that stream with an ease and rapidity that were astonishing. When he had seen each division once in the daytime and once at night, his education was so nearly complete that he took out a 'daylight' license; a few trips later he took out a full license, and went to piloting day and night--and he ranked A 1, too.
Mr. Bixby placed me as steersman for a while under a pilot whose feats of memory were a constant marvel to me. However, his memory was born in him, I think, not built. For instance, somebody would mention a name. Instantly Mr. Brown would break in--
'Oh, I knew HIM. Sallow-faced, red-headed fellow, with a little scar on the side of his throat, like a splinter under the flesh. He was only in the Southern trade six months. That was thirteen years ago. I made a trip with him. There was five feet in the upper river then; the "Henry Blake" grounded at the foot of Tower Island drawing four and a half; the "George Elliott" unshipped her rudder on the wreck of the "Sunflower"----'
'Why, the "Sunflower" didn't sink until----'
'I know when she sunk; it was three years before that, on the 2nd of December; Asa Hardy was captain of her, and his brother John was first clerk; and it was his first trip in her, too; Tom Jones told me these things a week afterward in New Orleans; he was first mate of the "Sunflower." Captain Hardy stuck a nail in his foot the 6th of July of the next year, and died of the lockjaw on the 15th. His brother died two years after 3rd of March,--erysipelas. I never saw either of the Hardys,--they were Alleghany River men,--but people who knew them told me all these things. And they said Captain Hardy wore yarn socks winter and summer just the same, and his first wife's name was Jane Shook--she was from New England-- and his second one died in a lunatic asylum. It was in the blood. She was from Lexington, Kentucky. Name was Horton before she was married.'
And so on, by the hour, the man's tongue would go. He could NOT forget any thing. It was simply impossible. The most trivial details remained as distinct and luminous in his head, after they had lain there for years, as the most memorable events. His was not simply a pilot's memory; its grasp was universal. If he were talking about a trifling letter he had received seven years before, he was pretty sure to deliver you the entire screed from memory. And then without observing that he was departing from the true line of his talk, he was more than likely to hurl in a long-drawn parenthetical biography of the writer of that letter; and you were lucky indeed if he did not take up that writer's relatives, one by one, and give you their biographies, too.
Such a memory as that is a great misfortune. To it, all occurrences are of the same size. Its possessor cannot distinguish an interesting circumstance from an uninteresting one. As a talker, he is bound to clog his narrative with tiresome details and make himself an insufferable bore. Moreover, he cannot stick to his subject. He picks up every little grain of memory he discerns in his way, and so is led aside. Mr. Brown would start out with the honest intention of telling you a vastly funny anecdote about a dog. He would be 'so full of laugh' that he could hardly begin; then his memory would start with the dog's breed and personal appearance; drift into a history of his owner; of his owner's family, with descriptions of weddings and burials that had occurred in it, together with recitals of congratulatory verses and obituary poetry provoked by the same: then this memory would recollect that one of these events occurred during the celebrated 'hard winter' of such and such a year, and a minute description of that winter would follow, along with the names of people who were frozen to death, and statistics showing the high figures which pork and hay went up to. Pork and hay would suggest corn and fodder; corn and fodder would suggest cows and horses; cows and horses would suggest the circus and certain celebrated bare-back riders; the transition from the circus to the menagerie was easy and natural; from the elephant to equatorial Africa was but a step; then of course the heathen savages would suggest religion; and at the end of three or four hours' tedious jaw, the watch would change, and Brown would go out of the pilot-house muttering extracts from sermons he had heard years before about the efficacy of prayer as a means of grace. And the original first mention would be all you had learned about that dog, after all this waiting and hungering.
