On Steamers.

A new self-recording indicator, marking mechanically every order signaled from the bridge of a steamer to the engine-room, consists of a drum, which revolves once in twelve hours, around which is placed a chart, containing a column for each word of command on the indicator in use, and ruled to show the fraction of a minute. When the order is given, it is marked at one on the chart The instrument does away with the possibility of conflicting evidence between the captain and engineer in case of accidents.
