(), n.[Heb. lg.] A Hebrew measure of liquids, containing 2.37 gills. W. H. Ward. Log (), n.[Icel. lg a felled tree, log; akin to E. lie. See Lie to lie prostrate.] 1. A bulky piece of wood which has not been shaped by hewing or sawing. 2. [Prob. the same word as in sense 1; cf. LG. log, lock, Dan. log, Sw. logg.] (Naut.) An apparatus for measuring the rate of a ship's motion through the water. The common log consists of the log-chip, or logship, often exclusively called the log, and the log line, the former being commonly a thin wooden quadrant of five or six inches radius, loaded with lead on the arc to make it float with the point up. It is attached to the log line by cords from each corner. This line is divided into equal spaces, called knots, each bearing the same proportion to a mile that half a minute does to an hour. The line is wound on a reel which is so held as to let it run off freely. When the log is thrown, the log-chip is kept by the water from being drawn forward, and the speed of the ship is shown by the number of knots run out in half a minute. There are Log v. t.[imp. & p. p.Logged (); p. pr. & vb. n.Logging ().] (Naut.), To enter in a ship's log book; as, to log the miles run. J. F. Cooper. Log v. i. 1. To engage in the business of cutting or transporting logs for timber; to get out logs. [U.S.] 2. To move to and fro; to rock. [Obs.] スポンサード リンク
