Cruisers.

ordinarily under easy steam, there must be capability of passing to a high rate of speed at short notice, which will be not only a severe trial to the machinery but consume the stock of coal at a rapid rate. Moveable coal depots as close to the scene of operations as possible will be a necessity in cases where no Imperial coaling station is comparatively near, but probably only the experience of a war of some duration can demonstrate the best system for coaling a large fleet operating in all parts of the world.

It is only of late years that the value of scouts to a squadron of battle ships has been recognised, and the method of utilising their services considered. For this and other invaluable experience we are indebted to our annual naval manœuvres. The ubiquity which steam confers in searching the ocean is an advantage which Nelson could not command, but which must in future relieve an admiral from all the anxiety of a foul wind when seeking information of an enemy which has escaped his vigilance. To have in addition one or two fast despatch vessels to warn detached squadrons of such movements, or return home with important intelligence—as Nelson sent a vessel home when he was satisfied that Villeneuve had left the West Indies—will be no less essential on some future occasion. They must be ready to run the gauntlet of the enemy's cruisers, and hence swiftness will be their chief security. They must not stop to fight unless brought to bay, and their armament should be of the lightest description. Up to the present time the development of this type
