XLOG, n.

1. A bulky piece or stick of timer unhewed. Pine logs are floated down rivers in America, and stopped at saw-mills. A piece of timber when hewed or squared, is not called a log, unless perhaps in constructing log-huts.

2. In navigation, a machine for measuring the rate of a ship's velocity through the water. The common log is a piece of board, forming the quadrant of a circle of about six inches radius, balanced by a small plate of lead nailed on the circular part, so as to swim perpendicular.
