for legitimate use. That 'spit and polish' was merely a really essential thing, overdone in the course of long years, cannot be too clearly kept in mind in these days of its decline as a naval accomplishment. The machinery of the far future, whether explosion engine or electric, will no doubt be kept beautifully clean, and this will increase its efficiency. But it is hardly likely to go short of oil on the grounds that 'lubrication is dirty,'—the odds are all against a slavish imitation of the days when guns were not fired for fear of damaging the paintwork. Spit and polish is the overgrown child of seeking after efficiency, but it is not the vice to which those who handle machinery are prone. Rather the errors of the navy of the future are likely, when they come, to take the form of an undue respect for speed. It is sure to be a good thing overdone that brings the decay, not a bad habit acquired. And so very possibly the decaying navy of the future will, just before that decay becomes obvious, make a fetish of speed at any price. It will probably—especially if the times are peaceful—sacrifice armour to increase speed. It will very possibly sacrifice a good deal of seaworthiness and stability to the same ideal. It will strive hard after the lightest possible form of construction, spend its energies perhaps in seeking to reduce superflous pounds in a 40,000-ton ship. Stores will be cut down, the supply of fuel kept meagre, and speeds undreamed of to-day become the ordinary thing.
