The training would naturally be more extended, as it would be a postgraduate course.
There is a difference to be noted between games like war games in which the mental powers are trained, and games like billiards, in which the nerves and muscles receive practically all the training; and the difference refers mainly to the memory.

Games of cards are a little like war games; and many books on games of cards have been written, expounding the principles on which they rest and giving rules to follow.

These books may be said to embody a science of card-playing.
No such book on naval strategy has appeared; and the obvious reason is that only a few rules of naval strategy have been formulated.
Staff training, therefore, cannot be given wholly by studying books; but possibly the scheme suggested to the department by the writer, when he was Aid for Operations, may be developed into a sort of illustrative literature, which can assist the memory.
By this scheme, a body of officers at the Navy Department would occupy their time wholly in studying war problems by devising and playing strategical and tactical games ashore and afloat.

After each problem had been solved to the satisfaction of the staff, each distinctive situation in the approved solution would be photographed in as small a space as practicable, preferably on a moving-picture film.

In the solution of problem 99; for instance, there might be 50 situations and therefore 50 photographs.
