To put the matter concretely, while the existing ownership of mines is a positive inducement to inefficient work, public ownership administered by a bureaucracy, if it would remove the technical deficiencies emphasized by Sir Richard Redmayne as inseparable from the separate administration of 3,000 pits by 1,500 different companies, would be only too likely to miss a capital advantage which a different type of administration would secure. It would lose both the assistance to be derived from the technical knowledge of practical men who know by daily experience the points at which the details of administration can be improved, and the stimulus to efficiency springing from the corporate pride of a profession which is responsible for maintaining and improving the character of its service. Professional spirit is a force like gravitation, which in itself is neither good nor bad, but which the engineer uses, when he can, to do his work for him. If it is foolish to idealize it, it is equally shortsighted to neglect it. In what are described _par excellence_ as "the services" it has always been recognized that _esprit de corps_ is the foundation of efficiency, and all means, some wise and some mischievous, are used to encourage it: in practice, indeed, the power upon which the country relied as its main safeguard in an emergency was the professional zeal of the navy and nothing else. Nor is {150} that spirit peculiar to the professions which are concerned with war. It is a matter of common training, common responsibilities, and common dangers. In all cases where difficult and disagreeable work is to be done, the force which elicits it is normally not merely money, but the public opinion and tradition of the little society in which the individual moves, and in the esteem of which he finds that which men value in success.
