Moderate dimensions in store- and coal-carriers would prove convenient, not only because it would facilitate taking in stores and coaling, if all the squadron were assembled at one place, but also if part were at one place and part at another. Division into several vessels, instead of concentration in a few, would give great flexibility to the system of supply. A single very capacious cargo-carrier might have to go first to one place and supply the ships there, and then go to supply the remaining ships lying at another anchorage. This would cause loss of time. The same amount of cargo distributed amongst two or more vessels would permit the ships at two or more places to be supplied simultaneously. You may have noticed that I have been dealing with the question as though stores and coal were to be transported direct to the men-of-war wherever they might be and put straight on board them from the carrying-vessels. There is, as you all know, another method, which may be described as that of 'secondary bases.' Speaking generally, each of our naval stations has a principal base at which considerable or even extensive repairs of the ships can be effected and at which stores are accumulated. Visits to it for the sake of repair being necessary, the occasion may be taken advantage of to replenish supplies, so that the maintenance of a stock at the place makes for convenience, provided that the stock is not too large. The so-called 'secondary base' is a place at which it is intended to keep in store coal and other articles in the hope that when war is in progress the supply of our ships may be facilitated. It is a supply, and not a repairing base. A comparison of the 'direct' system and 'secondary base' system may be interesting. A navy being maintained for use in war, it follows, as a matter of course, that the value of any part of its equipment or organisation depends on its efficiency for war purposes. The question to be answered is--Which of the two systems promises to help us most during hostilities? This does not exclude a regard for convenience and economy in time of peace, provided that care is taken not to push economy too far and not to make ordinary peace-time convenience impede arrangements essential to the proper conduct of a naval campaign. It is universally admitted that a secondary base at which stocks of stores are kept should be properly defended. This necessitates the provision of fortifications and a garrison. Nearly every article of naval stores of all classes has to be brought to our bases by sea, just as much as if it were brought direct to our ships. Consequently the communications of the base have to be defended. They would continue to need defending even if our ships ceased to draw supplies from it, because the communications of the garrison must be kept open. We know what happened twice over at Minorca when the latter was not done.
