Stage three of fire making uses a bow as a tension rod and a fly wheel. To begin the bow would wind around the stick; the person would then push down causing the stick the spin. When the tension was released from the bow the fly wheel would continue spinning causing the rope to be re-spun around the stick. This would cause friction below resulting in fire.

"The apron is supported and carried by flanged wheels, fixed at distances apart upon shafts, one of the shafts begin placed near the mill, and the other at the outer extremity of apron. A chain band, adapted to a chain wheel on the end of the feeling roll shaft, and leading from thence to a similar wheel upon the end of the flageshaft nearest the mill, communicates motion to the apron. It should travel somewhat slower that the surface of the rolls." -Commissioner, 1865

"Decorticator for ramie, jute, hemp, flax, and other textiles in green stalks. The machine is quadruple in its action. It consists in four feeders and four cleaners, inside of which revolves, horizontally, a large cogged wheel acting as a circular carrier. It brings the crushed plant in, and draws from it, the revolving cleaners, as follows: A, crushing rollers, through which the green stalks are passed, and placed on the rim of the large cogged wheel or circular carrier. B,rim of the carrier, on which hangs the flattened plant coming from the rollers. C, revolving cleaners, furnished with knives attracting the plant while it is drawn by the circular motion of the carrier. D, small cog-wheels in contact with the large wheels, and keeping the plant under pressure. F, projecting bar to direct the fiber into the cleaners. G, opening to take off the cleaned fiber." -Watts, 1874

A warship is a ship that is built and primarily intended for combat. Warships are usually built in a completely different way than merchant ships. As well as being armed, warships are designed to withstand damage and are usually faster and more maneuverable than merchant ships. Unlike a merchant ship, a warship typically only carries weapons, ammunition and supplies for its own crew (rather than merchant cargo). Warships usually belong to a navy, though they have sometimes been operated by individuals or companies.

A floating dock is a platform or ramp supported by pontoons. These are usually joined to the shore with a ramp that rests upon the dock on rollers, to adjust for the vertical movement of the dock. The dock is usually held in place by vertical poles embedded in the soil under the water or by anchored cables. Frequently used in marinas for small boats, this type of dock maintains a fixed vertical relationship to watercraft secured to it, independent of tidal, river, or lake elevation. It is less suited for larger craft as the docks cannot support large structures or cranes. In some regions of the world, a floating dock is called a pontoon.

The Yazoo River was of major importance during the American Civil War. The first electrically detonated underwater mine was used on the river in 1862 near Vicksburg to sink the Union ironclad USS Cairo. The last section of the Cairo was raised on December 12, 1964. It has been restored and is now on permanent display to the public at the Vicksburg National Military Park. There are 29 sunken ships from the Civil War beneath the waters of the river.
