To heave the log
(gcide) | Log \Log\, n. [Icel. l[=a]g 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.
[1913 Webster]
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.
[1913 Webster]
Note: 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 improved
logs, consisting of a piece of mechanism which, being
towed astern, shows the distance actually gone through
by the ship, by means of the revolutions of a fly,
which are registered on a dial plate.
[1913 Webster]
3. Hence: The record of the rate of speed of a ship or
airplane, and of the course of its progress for the
duration of a voyage; also, the full nautical record of a
ship's cruise or voyage; a log slate; a log book.
[1913 Webster +PJC]
4. Hence, generally: A record and tabulated statement of the
person(s) operating, operations performed, resources
consumed, and the work done by any machine, device, or
system.
[1913 Webster +PJC]
5. (Mining) A weight or block near the free end of a hoisting
rope to prevent it from being drawn through the sheave.
[1913 Webster]
6. (computers) A record of activities performed within a
program, or changes in a database or file on a computer,
and typically kept as a file in the computer.
