intelligible to the most untaught capacity. Everybody can understand convertibility; every one sees that what can be at any moment exchanged for five pounds, is worth five pounds. Regulation by the price of bullion is a more complex idea, and does not recommend itself through the same familiar associations. There would be nothing like the same confidence, by the public generally, in an inconvertible currency so regulated, as in a convertible one: and the most instructed person might reasonably doubt whether such a rule would be as likely to be inflexibly adhered to. The grounds of the rule not being so well understood by the public, opinion would probably not enforce it with as much rigidity, and, in any circumstances of difficulty, would be likely to turn against it; while to the government itself a suspension of convertibility would appear a much stronger and more extreme measure, than a relaxation of what might possibly be considered a somewhat artificial rule. There is therefore a great preponderance of reasons in favour of a convertible, in preference to even the best regulated inconvertible currency. The temptation to over-issue, in certain financial emergencies, is so strong, that nothing is admissible which can tend, in however slight a degree, to weaken the barriers that restrain it.
§ 3.Although no doctrine in political economy rests on more obvious grounds than the mischief of a paper currency not maintained at the same value with a metallic, either by convertibility, or by some principle of limitation equivalent to it; and although, accordingly, this doctrine has, though not till after the discussions of many years, been tolerably effectually drummed into the public mind; yet dissentients are still numerous, and projectors every now and then start up, with plans for curing all the economical evils of society by means of an unlimited issue of inconvertible paper. There is, in truth, a great charm in the idea. To be able to pay off the national debt, defray the expenses of government without taxation, and in fine, to make the fortunes of the whole com-
