"'The great ugly masses of floating timber move slowly along under the care of a pilot, and the lumberers ride upon the rafts, often without shelter or protection from the weather. They guide themselves by long and powerful poles fixed on pivots, and which act as rudders. As they journey down the stream they sing and shout and make the utmost noise and riot. If there comes a storm or a change of weather, the pilot steers his convoy into some safe creek for the night, and secures it as best he can.
