But the reader must turn to Chapter VIII of "Life on the Mississippi" and read, or reread, the pages which follow this extract—nothing can better convey the difficulties of piloting. That Samuel Clemens had the courage to continue is the best proof, not only of his great love of the river, but of that splendid gift of resolution that one rarely fails to find in men of the foremost rank.

RIVER DAYS

Piloting was only a part of Sam Clemens's education on the Mississippi. He learned as much of the reefs and shallows of human nature as of the river-bed. In one place he writes:

In that brief, sharp schooling I got personally and familiarly
acquainted with all the different types of human nature that are to
be found in fiction, biography, or history.

All the different types, but most of them in the rough. That Samuel Clemens kept the promise made to his mother as to drink and cards during those apprentice days is well worth remembering.

Horace Bixby, answering a call for pilots from the Missouri River, consigned his pupil, as was customary, tonne of the pilots of the "John J. Roe," a freight-boat, owned and conducted by some retired farmers, and in its hospitality reminding Sam of his Uncle John Quarles's farm. The "Roe" was a very deliberate boat. It was said that she could beat an island to St. Louis, but never quite overtake the current going down-stream. Sam loved the "Roe." She was not licensed to carry passengers, but she always had a family party of the owners' relations aboard, and there was a big deck for dancing and a piano in the cabin. The young pilot could play the chords, and sing, in his own fashion, about a grasshopper that; sat on a sweet-potato vine, and about—

An old, old horse whose name was Methusalem,
Took him down and sold him in Jerusalem,
A long time ago.

The "Roe" was a heavenly place, but Sam's stay there did not last. Bixby came down from the Missouri, and perhaps thought he was doing a fine thing for his pupil by transferring him to a pilot named Brown, then on a large passenger-steamer, the "Pennsylvania." The "Pennsylvania" was new and one of the finest boats on the river. Sam Clemens, by this time, was accounted a good steersman, so it seemed fortunate and a good arrangement for all parties.
