'A torpedo corps has been recently formed for New South Wales, under Major Cracknell, the chief electrician of the colony, and this body of volunteers are being well trained in all the details appertaining to the manipulation of the weapon they are to use. The chief reliance of New South Wales at present will have to be placed in what may called fixed torpedoes, in contradistinction to "fish" torpedoes, or other mechanical arrangements of a similar class. These torpedoes will be sunk in various known spots in the channels along which an enemy's ship would have to pass in the event of making an attack upon Sydney; they will be connected by submarine cables with the necessary stations on either side of the harbour.'
