The cause that drew forth the famous Drapier letters--why Swift chose to spell the word _draper_ with an _i_ no one has ever explained--appears at first sight hardly worthy of the occasion. Ireland wanted a copper coinage, and Walpole, who was then the Prime Minister, had given a patent for the purpose to a person called Wood, part of the profits of which patent were to go to the Duchess of Kendal, the king's mistress. There seems no reason to think that the pennies produced by Wood were in any way inferior to the existing English ones, and Sir Isaac Newton--who was at the time Master of the Mint--declared that, if anything, they were rather better. The real wrong, the real insult, was that the patent was granted by the Minister without reference to the Lord-Lieutenant, to the Irish Parliament, or to any single human being in Ireland. It was a proof the more of that total indifference with which the interests of Ireland were regarded, and it was upon this score that Swift's wrath exploded like a bomb. The line he chose to take was to attack the patent, not as a monstrous job--which undoubtedly it was--but from the point of view of the value of the pennies. Assuming the character of a tradesman, he adjured all classes of the community, down to the very beggars, not to be induced to accept them. Assured them that for the benefit of Mr. Wood, "a mean man, a hardware dealer," every human being in Ireland was about to be deliberately robbed and ruined. His logic sounded unanswerable to the ignorant. His diatribes produced the most extraordinary effect. A terrific panic set in, and so overwhelming was the sensation that the Ministers in the end found it necessary to cancel the patent, and suspend the issue of Wood's halfpence. For the first time in Irish history public opinion, unsupported by arms, had carried its point: an epoch of vast importance in the history of every country.
