Definition: Percina caprodes
, n. [Icel. l[=a]g a felled tree, log; akin to E. lie.
to lie prostrate.]
1. A bulky piece of wood which has not been shaped by hewing
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.
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.
