FOOTNOTES:

[1] The "stroke" of an engine is the distance traveled by the cross-head of the piston in making a complete revolution of the wheel—equal to twice the length of the crank on the water-wheel shaft. If the crank is three feet long, the stroke will be six feet. The stroke of the "Grey Eagle" of the Minnesota Packet Company was seven feet; that of the "J. M. White", lower river boat, was eleven feet. The cylinders of course equaled the full stroke in length. The longer the crank the greater the purchase, but at a consequent loss in the number of revolutions of the wheel per minute.

[2] "Mud" Clerk: Second clerk, whose duty it was to go out in all weathers, upon the unpaved levees and deliver or receive freight. As the levees were usually muddy in rainy weather, the name became descriptive of the work and condition of the second clerk.
