Log boom: a barrier placed in a river or lake, designed to collect and/or contain floating logs timbered from nearby forests.
Splash dam: a temporary wooden dam used to raise the water level in rivers and streams to float logs downstream to sawmills.
Sluice gate: a wooden or metal plate which slides into grooves in the sides of a sluice channel. Sluice gates are commonly used to control water levels and flow rates in rivers and canals.
Flume: an open artificial water channel, in the form of a gravity chute that leads from a diversion dam or weir completely aside a natural flow. Often, the flume is an elevated box structure (typically wood) that follows the natural contours of the land.
Peavey or peavey hook: a logging tool consisting of a handle, generally from 30 to 50 inches long (0.75 to 1.25 m), with a metal spike protruding from the end. The spike is rammed into a log, then a hook (at the end of an arm attached to a pivot a short distance up the handle) grabs the log at a second location. Once engaged, the handle gives the operator leverage to roll or slide or float the log to a new position.
Faller: a person who cuts down and falls trees.
Swamper: an assistant in the logging industry who clears roads.
Teamster: a person who drives a team of draft animals, usually a wagon drawn by oxen, horses or mules.
Skidding: the process in which logs are transported from the cutting site in the forest to a landing where they are loaded onto trucks, railroad cars or flumes and sent to the mill.
Froe or frow: a tool for cleaving wood by splitting it along the grain. Froes are used in combination with wooden mallets to split timber, to make planks, wooden shingles, or kindling.
Gin pole: a rigid pole with a pulley on the end used for the purpose of lifting.
