โฆ Synopsis
During the war the Germans showed that they had taken to heart the work of Langley and his successors, for the Allies were much at the mercy of their enemies. Over seven million dollars damage was done in London in a single night by German flyers, and no commensurate damage was done to the German works.
The lecture on physics in navigation by Dr. Smith, Director of Scientific Research in the Admiralty, covers a number of topics among which may be noted the new process of deep-sea sounding by the "echo" method. The ingenious system of guiding a ship through a narrow channel by the so-called "leader cable" is described, but while in almost all other cases some authority is quoted, this article has no such information. Was the method invented in America, and if so, is this the reason for lack of acknowledgment? HENRY LEFFMANN.
