 | | The speed of a vessel at sea is reckoned by knots, each knot being equal to a nautical mile (6,076 feet), which is slightly longer than a mile measured on land (5,280 feet). |
 | | Six nautical or geographical miles are about equal to seven statute English miles, so that a ship making 12 “knots” an hour is actually traveling at the rate of 14 statue miles per hour. |
 | | At one end of this line the ‘log’, which is a piece of flat, light wood, generally triagular in shape, weighted along one edge, is attached, much in the same way as a boy fastens his kite to the string, so that it floats vertically, with it’s flat surface presented to the ship. |
