their belching stacks reared high against the blue—a towering front of trade. It was glorious to nose one's way to a place in that stately line, to become a unit, however small, of that imposing fleet. At St. Louis Sam borrowed from Mr. Moffett the funds necessary to make up his first payment, and so concluded his contract. Then, when he suddenly found himself on a fine big boat, in a pilot-house so far above the water that he seemed perched on a mountain—a "sumptuous temple"—his happiness seemed complete.
XXIII. The Supreme Science
In his Mississippi book Mark Twain has given us a marvelous exposition of the science of river-piloting, and of the colossal task of acquiring and keeping a knowledge requisite for that work. He has not exaggerated this part of the story of developments in any detail; he has set down a simple confession.
Serenely enough he undertook the task of learning twelve hundred miles of the great changing, shifting river as exactly and as surely by daylight or darkness as one knows the way to his own features. As already suggested, he had at least an inkling of what that undertaking meant. His statement that he "supposed all that a pilot had to do was to keep his boat in the river" is not to be accepted literally. Still he could hardly have realized the full majesty of his task; nobody could do that—not until afterward.
Horace Bixby was a "lightning" pilot with a method of instruction as direct and forcible as it was effective. He was a small man, hot and quick-firing, though kindly, too, and gentle when he had blown off. After one rather pyrotechnic misunderstanding as to the manner of imparting and acquiring information he said:
"My boy, you must get a little memorandum-book, and every time I tell you a thing put it down right away. There's only one way to be a pilot, and that is to get this entire river by heart. You have to know it just like A B C."
So Sam Clemens got the little book, and presently it "fairly bristled" with the names of towns, points, bars, islands, bends, and reaches, but it made his heart ache to think that he had only half of the river set down; for, as the "watches" were four hours off and four hours on, there were long gaps during which he had slept.
The little note-book still exists—thin and faded, with black water-proof covers—its neat, tiny, penciled notes still, telling, the story of that first trip. Most of them are cryptographic abbreviations, not readily deciphered now. Here and there is an easier line:
MERIWEATHER'S BEND
1/4 less 3—[Depth of water. One-quarter less than three fathoms.]——run shape of upper bar and go into the low place in willows about 200(ft.) lower down than last year.
One simple little note out of hundreds far more complicated. It would take days for the average mind to remember even a single page of such statistics. And those long four-hour gaps where he had been asleep, they are still there, and somehow, after more than fifty years, the old heart-ache is still in them. He got a new book, maybe, for the next trip, and laid this one away.
There is but one way to account for the fact that the man whom the world knew as Mark Twain—dreamy, unpractical, and indifferent to details—ever persisted in acquiring knowledge like that—in the vast, the absolutely limitless quantity necessary to Mississippi piloting. It lies in the fact that he loved the river in its every mood and aspect and detail, and not only the river, but a steam boat; and still more, perhaps, the freedom of the pilot's life and its prestige. Wherever he has written of the river—and in one way or another he was always writing of it we feel the claim of the old captivity and that it still holds him. In the Huckleberry Finn book, during those nights and days with Huck and Nigger Jim on the raft—whether in stormlit blackness, still noontide, or the lifting mists of morning—we can fairly "smell" the river, as Huck himself would say, and we know that it is because the writer loved it with his heart of hearts and literally drank in its environment and atmosphere during those halcyon pilot days.
So, in his love lay the secret of his marvelous learning, and it is recorded (not by himself, but by his teacher) that he was an apt pupil. Horace Bixby has more than once declared:
"Sam was always good-natured, and he had a natural taste for the river. He had a fine memory and never forgot anything I told him."
Mark Twain himself records a different opinion of his memory, with the size of its appalling task. It can only be presented in his own words. In the pages quoted he had mastered somewhat of the problem, and had begun to take on airs. His chief was a constant menace at such moments:
One day he turned on me suddenly with this settler:
"What is the shape of Walnut Bend?"
He might as well have asked me my grandmother's opinion of protoplasm. I reflected respectfully, and then said I didn't know it had any particular shape. My gun-powdery chief went off with a bang, of course, and then went on loading and firing until he was out of adjectives.... I waited. By and by he said:
"My boy, you've got to know the shape of the river perfectly. It is all there is left to steer by on a very dark night. Everything is blotted out and gone. But mind you, it hasn't the same shape in the night that it has in the daytime."
"How on earth am I ever going to learn it, then?"
"How do you follow a hall at home in the dark? Because you know the shape of it. You can't see it."
"Do you mean to say that I've got to know all the million trifling variations of shape in the banks of this interminable river as well as I know the shape of the front hall at home?"
"On my honor, you've got to know them better than any man ever did know the shapes of the halls in his own house."
"I wish I was dead!"
"Now, I don't want to discourage you, but——"
"Well, pile it on me; I might as well have it now as another time."
"You see, this has got to be learned; there isn't any getting around it. A clear starlight night throws such heavy shadows that, if you didn't know the shape of a shore perfectly, you would claw away from every bunch of timber, because you would take the black shadow of it for a solid cape; and, you see, you would be getting scared to death every fifteen minutes by the watch. You would be fifty yards from shore all the time when you ought to be within fifty feet of it. You can't see a snag in one of those shadows, but you know exactly where it is, and the shape of the river tells you when you are coming to it. Then there's your pitch-dark night; the river is a very different shape on a pitch-dark night from what it is on a starlight night. All shores seem to be straight lines, then, and mighty dim ones, too; and you'd run them for straight lines, only you know better. You boldly drive your boat right into what seems to be a solid, straight wall (you know very well that in reality there is a curve there), and that wall falls back and makes way for you. Then there's your gray mist. You take a night when there's one of these grisly, drizzly, gray mists, and then there isn't any particular shape to a shore. A gray mist would tangle the head of the oldest man that ever lived. Well, then, different kinds of moonlight change the shape of the river in different ways. You see——"
"Oh, don't say any more, please! Have I got to learn the shape of the river according to all these five hundred thousand different ways? If I tried to carry all that cargo in my head it would make me stoop-shouldered."
"No! you only
