Narrative: A log is an instrument for estimating the speed of a ship. It is towed astern and is so constructed that it turns as it is pulled through the water, the number of turns is automatically counted by the gauges on the log. It then had to be taken and read. Later, an attached gauge on deck did the recording of the turns. Walkers in England were the manufacturers and are still in existence.
