Copy letter from H [Henry] Middleton, to the Editor of the Daily News [John Stuart Hodgson] Responding to the 'Daily News' leader on submarines, expressing astonishment that the main consideration in such vessels was not mentioned, to bring food to Britain safely in time of war. He considers the problems involved, and the potential for vessels travelling just awash. He describes his own experiments of thirty years ago, and the need for horizontal fins, or wings, such as whales have. He also outlines the attacking potential of such vessel using a towable and dirigible mine against surface vessels. 24 November 1925
