There were, moreover, other reasons why the press-gang was to the Navy an indispensable appendage--reasons perhaps of little moment singly, but of tremendous weight in the scale of naval necessity when lumped together and taken in the aggregate. Of these the most prominent was that fatal flaw in naval administration which Nelson was in the habit of anathematising as the "Infernal System." Due partly to lack of foresight and false economy at Whitehall, partly to the character of the sailor himself, it resolved itself into this, that whenever a ship was paid off and put out of commission, all on board of her, excepting only her captain and her lieutenants, ceased to be officially connected with the Navy. Now, as ships were for various reasons constantly going out of commission, and as the paying off of a first-second-or third-rate automatically discharged from their country's employ a body of men many hundreds in number, the "lowering" effects of such a system, working year in, year out, upon a fleet always in chronic difficulties for men, may be more readily imagined than described. To a certain limited extent the loss to the service was minimised by a process called "turning over"; that is to say, the company of a ship paying off was turned over bodily, or as nearly intact as it was possible to preserve it, to another ship which at the moment chanced to be ready, or making ready, for sea. Or it might be that the commander of a ship paying off, transferred to another ship fitting out, carried the best men of his late command, commonly known as "old standers," along with him.
