There is nothing in the nature of things that I know of to prevent submarine warfare being carried on in the future to a very large extent. This development will probably follow triple lines: (1) Vessels for the defence of ports and harbours, with sufficient means of proceeding outside to give the defence a certain limited power of attack in the approaches; (2) Vessels primarily designed for attack, and therefore capable of proceeding to sea for considerable distances; and (3) Smaller vessels to be taken to sea in ships, as part of their equipment, and capable of being lowered to take part in a battle, and raised again, and re-stowed on board when no longer needed in action. All these types of vessel will need to be endowed with the power of passing easily and quickly from the floating to the submerged condition, and back again to the surface when necessary; but the boats of the second class in the foregoing category will doubtless be developed to an extent as yet anticipated by very few of us, in respect alike of their ability to proceed for great distances below water, and of their ability to steam satisfactorily afloat when submergence is needless.

All who are acquainted with the structure of waves, so to speak, will be aware that wave disturbance diminishes very rapidly as we go down below the surface, and will consequently understand that when once we have succeeded in giving submarines a great range of under-water travel, we shall have endowed them with the capability of avoiding at pleasure in bad weather the tempestuous surface of the sea, with all the drawbacks to speed which stormy seas impose upon ships, and especially upon comparatively small vessels. In order to bring about this advantage, science has to effect, no doubt, immense improvements in the production of storage of air, or of its equivalent; but there is great reason to believe that the demand will bring the supply, as in so many other matters. Nor must it be forgotten that this is a branch of science for the development of which the ship proper, as we have hitherto known it, has offered few, if any, inducements. I do not know how the sight of an ordinary modern ship of war strikes the eyes of others, but for my part I never look at one, with its vast and monstrous assemblage of gaping mouths of funnels, pipes, and cowls, without thinking that our method of supplying breathing gas to men below in a ship is at present of a very elementary and unsatisfactory character. It is certainly the roughest and readiest method that could well be adopted. Nor is it without a sense of satisfaction that one knows that the submarine ship will at least sweep away these ugly and towering excrescences, and force us to resort much more than at present to the chemical and mechanical arts for the ventilation of vessels.

The development of the sea-going submarine will bring with it, doubtless, many improvements in the vessels which have been first mentioned, viz., vessels for the defence of ports and their approaches. It is not possible yet to say to what extent the “Holland” boats building at Barrow will prove fairly satisfactory, although my acquaintance with this class of vessel for several years past has given me a favourable impression of it—favourable, that is, as furnishing many elements of initial success. More than this could not be reasonably expected; nor can we doubt that with the skill of both the Admiralty designers and those of the great manufacturing establishment which has produced the first few vessels concentrated upon this class of boat, immense improvements may be confidently anticipated.

Of the third class of vessels before referred to the Goubet boat may be regarded as a commencing type. The principle of this boat appears to be that of carrying and launching torpedoes from external supports, the size and buoyancy of the vessels being very small by comparison with those of vessels which carry their torpedoes inside. M. Goubet appears to go beyond this principle, and to have other ideas, which are mentioned in the text of this work. Suffice it here to say that the idea of relieving the submarine boat from the necessity of carrying its torpedoes with it, goes a long way towards furthering the use of submarine torpedo craft carried on the decks, or at the davits of battleships and cruisers.

If one may contrast for a moment the present attempts at aerial navigation with the concurrent attempts at submarine navigation, one quickly sees how terribly the æronaut is handicapped as compared with the under-water sailor. The advantage of the dense medium which the sea offers to the submarine navigator is precisely the same as it has offered from the beginning of time to the surface navigator, and nothing new is needed to sustain the submarine ship, whereas the unhappy man who seeks to navigate the air has to obtain from a medium of extraordinary levity the support necessary for keeping him aloft. The difference between the specific gravity of air (of which ships are full) and of water is so great by comparison between the specific gravity of any gas available for filling aerial-ships and that of air, that the problem of the submarinist is easy indeed compared with the other. But it is in the face of this initial and enormous difficulty that the æronauts of to-day have apparently persuaded themselves that they can successfully float their balloon-ship in mid-air, and propel it not only against the rapid tides of the air in which it floats, but also drive it at a good additional speed. When men are to be found capable of committing their fortunes, and even their lives, to navigation of this kind, it is not surprising to find that the far easier problem of navigating the seas beneath the surface has won the attention and the effort of enterprising men. They certainly have chosen, if the humbler, also the more practical and promising field of operation. I doubt not that they have likewise chosen the more fruitful field.

It is worthy of remark that it is once again in connection with the arts of war that a great extension of human progress has been commenced. But for the temptation of gaining equality with, and even mastery over, our possible foes, the art of submarine navigation would certainly not have been attracting the attention of some of our best and most scientific men, who are once again eagerly developing—

“Those dire implements

Which sombre science with unpitying pains,

That love of neither man nor God restrains,

To warring foes presents.”

One can only be thankful that the world is so constituted and so ruled, that out of seeming evil often comes great good to men.

I have not been asked to say anything of the book with which these lines are associated. I may nevertheless remark that I have had an opportunity of hastily looking through the author’s proofsheets, and have formed the opinion that it is a most timely and highly instructive work, and one which gives to the non-technical world an extremely good review of all that has been done in the way of submarine war vessels, while the technical man into whose hands it may come will be compelled, by its great interest and by its clever record of facts, to read every page of it.
