Other methods used by the anti- submarine school involve polarised light and infra-red radiations, which, incidentally, are of immense value to surface men-of-war as means of invisible signalling.

In fact, the work being done at Portland is invaluable, not only to the Navy, but to mercantile ship- ping and navigation in general. Sound ranging by beam waves, for instance, onables hydrographic work to be carried on in darkness or fog, and is also employed to determine the presence of icebergs. New Perils.
