In the summer of this year he was again in London, and Pope asked him to spend a week in his 'Tusculum.' One promotion followed another until Berkeley became Dean of Derry, with an income of from £1,500 to £2,000 a year. He did not hold this dignified position long, having conceived the magnificent but Utopian idea of founding a Missionary College in the Bermudas--the 'Summer Isles' celebrated in the verse of Waller and of Marvell--for the conversion of America.
And now Berkeley exhibited his amazing power of influencing other men. The members of the Scriblerus Club laughed at the Dean's project, but so powerful was his eloquence, that 'those who came to scoff remained to subscribe.' Moreover, with Sir Robert Walpole as Prime Minister, he actually obtained a grant from the State of £20,000 in order to carry out the project, the king gave a charter, and to crown all, Sir Robert put his own name down for £200 on the list of subscribers. 'The scheme,' says Mr. Balfour, 'seems now so impracticable that we may well wonder how any single person, let alone the representatives of a whole nation, could be found to support it. In order that religion and learning might flourish in America, the seeds of them were to be cast in some rocky islets severed from America by nearly six hundred miles of stormy ocean. In order that the inhabitants of the mainland and of the West Indian colonies might equally benefit by the new university, it was to be placed in such a position that neither could conveniently reach it.'[60] Berkeley, who had recently married, left England for Rhode Island, where he stayed for about three years and wrote _Alciphron_ (1732), in which he attacks the freethinkers under the title of _Minute Philosophers_. Then on learning from Walpole that the promised money 'would most undoubtedly be paid as soon as suits public convenience' which would be never, he returned to England, and through the Queen's influence was made Bishop of Cloyne. In that diocese eighteen years of his life were spent. In the course of them he published the _Querist_ (1735-1737), an _Essay on the Social State of Ireland_ (1744), and, in the same year, _Siris_, which contains the bishop's famous recipe for the use of tar water followed by much philosophical disquisition. The remedy, which was afterwards praised by the poet Dyer in _The Fleece_, became instantly popular. 'We are now mad about the water,' Horace Walpole wrote; 'the book contains every subject from tar water to the Trinity; however, all the women read it, and understand it no more than if it were intelligible.' Editions of _Siris_ followed each other in rapid succession, and it was translated into French and German. The work is that of an enthusiast, and it should be read not for its argument, but for its wealth of suggestiveness, and for what Mr. Balfour calls 'a certain quality of moral elevation and speculative diffidence alien both to the literature and the life of the eighteenth century.' Berkeley had himself the profoundest faith in the panacea which he advocated. 'From my representing tar water,' he writes, 'as good for so many things, some, perhaps, many conclude it is good for nothing. But charity obligeth me to say what I know, and what I think, howsoever it may be taken. Men may conjecture and object as they please, but I appeal to time and experience.'
