[

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 .
