Rh When we come to consider it—nothing, except with great good luck. Weak units—and numbers must mean relatively weak units—cannot even act as scarecrows. Spread over the ocean they would be merely so many attractive prizes to armoured corsairs. Grouped at strategical points they would be little more dangerous—a single large hostile cruiser with moderately large guns could steam round and sink them out of range of their pop-guns. Protected cruisers on the trade routes would benefit no British traders at all, unless it were the makers of monuments to the departed.

Consequently armoured cruisers must be employed. These are necessarily few: and to send them scouring the ocean on the off chance of meeting an enemy would be wasting them completely. They are much better employed from bases, whence they can observe hostile harbours and run down anything that issues out and catch anything trying to return.

The rub is that something now and again is sure to get out; and having got out, to do some mischief. It will be difficult to convince the British public that a corsair getting out is hardly likely to average one prize a day and hardly likely to be able to go more than a week without coaling. Wherever it goes to coal will be its 'earth,' and there, ere it can reissue, a big armoured cruiser with a large coal endurance ought to be able to get and wait for it coming out.
