Publisher description
Excerpt from A Note on the History of Submarine War This is to be achieved by means of two side tanks into which water can be admitted through perforations, and from which it can be blown out again by forcing the inner side of each tank outwards. These false sides are made tight with leather suckers and moved by winding hand-screws - a crude and inefficient mechanism, but a proof that the problem had been correctly grasped. For a really practical solution of this and the many other difficulties involved in submarine navigation, the resources of applied science were then hopelessly inadequate; it was not until after more than 300 years of experiment that inventors were in a position to command a mechanism that could carry out their ideas effectively. The record of these three centuries of experiment is full of interest, for it shows us a long succession of courageous men taking up one after another the same group of scientific problems and bringing them, in spite of all dangers and disasters, gradually nearer to a final solution. Many nations contributed to this work, but especially the British, the American, the Dutch, the French, the Spanish, the Swedish, the Russian, and the Italian. The part played by each of them has been, on the whole, characteristic. The British were the first, as practical seamen, to put forward the original idea, gained from the experience of their rivalry with Spain; they have also succeeded, at the end of the experimental period, in making the best combined use of the results of the long collaboration.
