They were willing to have the benefit of his assistance, but their favours were reserved for men more wholly their own. Various things were, indeed, talked of for Swift--the secretaryship to the proposed embassy of Lord Berkeley in Vienna, a prebend of Westminster, the office of historiographer-royal; nay, even a bishopric in the American colonies: but all came to nothing. Swift, at the age of forty-three, and certified by Addison as "the greatest genius of the age," was still only an Irish parson, with some 350_l._ or 400_l._ a year. How strange if the plan of the Transatlantic bishopric had been carried out, and Swift had settled in Virginia! Meanwhile, though neglected by the English Whigs, Swift had risen to be a leader among the Irish clergy, a great man in their convocations and other ecclesiastical assemblies. The object which the Irish clergy then had at heart was to procure from the Government an extension to Ireland of a boon granted several years before to the clergy of England: namely, the remission of the tax levied by the Crown on the revenues of the Church since the days of Henry VIII. in the shape of tenths and first-fruits. This remission, which would have amounted to about 16,000_l._ a year, the Whigs were not disposed to grant, the corresponding remission in the case of England not having been followed by the expected benefits. Archbishop King and the other prelates were glad to have Swift as their agent in this business; and, accordingly, he was absent from Ireland for upwards of twelve months continuously in the years 1708 and 1709. It was during this period that he set London in a roar by his famous Bickerstaff hoax, in which he first predicted the death of Partridge, the astrologer, at a particular day and hour, and then nearly drove the wretched tradesman mad by declaring, when the time was come, that the prophecy had been fulfilled, and publishing a detailed account of the circumstances. Out of this Bickerstaff hoax, and Swift's talk over it with Addison and Steele, arose the _Tatler_, prolific parent of so many other periodicals.
