When one nation is at war with another, there is no doubt that the two governments connive at, and often encourage, the most atrocious libels on each other, to madden the people to preserve their independence, and contribute cheerfully to the expenses of the war. France and England formerly complained of Holland--the Athenians employed the same policy against the Macedonians and Persians. Such is the origin of a vast number of supposititious papers and volumes, which sometimes, at a remote date, confound the labours of the honest historian, and too often serve the purposes of the dishonest, with whom they become authorities. The crude and suspicious libels which were drawn out of their obscurity in Cromwell's time against James the First have overloaded the character of that monarch, yet are now eagerly referred to by party writers, though in their own days they were obsolete and doubtful. During the civil wars of Charles the First such spurious documents exist in the forms of speeches which were never spoken; of letters never written by the names subscribed; printed declarations never declared; battles never fought, and victories never obtained! Such is the language of Rushworth, who complains of this evil spirit of party forgeries, while he is himself suspected of having rescinded or suppressed whatever was not agreeable to his patron Cromwell. A curious, and perhaps a necessary list might be drawn up of political forgeries of our own, which have been sometimes referred to as genuine, but which are the inventions of wits and satirists! Bayle ingeniously observes, that at the close of every century such productions should be branded by a skilful discriminator, to save the future inquirer from errors he can hardly avoid. "How many are still kept in error by the satires of the sixteenth century! Those of the present age will be no less active in future ages, for they will still be preserved in public libraries." The art and skill with which some have fabricated a forged narrative render its detection almost hopeless. When young Maitland, the brother to the secretary, in order to palliate the crime of the assassination of the Regent Murray, was employed to draw up a pretended conference between him, Knox, and others, to stigmatise them by the odium of advising to dethrone the young monarch, and to substitute the regent for their sovereign, Maitland produced so dramatic a performance, by giving to each person his peculiar mode of expression, that this circumstance long baffled the incredulity of those who could not in consequence deny the truth of a narrative apparently so correct in its particulars! "The fiction of the warming-pan enclosing the young Pretender brought more adherents to the cause of the Whigs than the Bill of Rights," observes Lord John Russell.
