The correspondence between Swift and Bolingbroke completed the series, which Pope complained was printed without his consent. Of the eight letters from Bolingbroke, seven were written in conjunction with the poet. These joint compositions, like the partnership letters of Gay, are exactly those which would have been returned to Pope. One of the number furnishes evidence, which almost amounts to a demonstration, that the collection of 1741 proceeded from himself. When he brought out the avowed edition of his letters in 1737, he inserted at the end of the volume a letter of Swift, a letter of his own, and the joint letter from himself and Bolingbroke, of which Curll had obtained a copy. This little supplement was ushered in by a notice which says, "Since the foregoing sheets were printed off, the following letters having been published without the consent of their writers, we have added them, though not in the order of time." Whatever the motive the announcement was deceptive. The letter of Swift was his reply to the joint letter of Pope and Bolingbroke--that very reply which the poet boasted a month or two before could not be produced surreptitiously, because it had never been out of his custody. Nobody else, by his own showing, had the power to make it public, no earlier impression of it is known to exist, and, as will be seen by comparing it with the copy from the Oxford papers, it was printed with omissions and variations, which must have been the act of the poet, or he would have restored the genuine readings when he included it in his appendix. In juxtaposition with it is a letter from Pope to Swift, dated December 10, 1725, which in like manner has never been found in any prior publication, and which of all his letters to the Dean is the single one we are certain was in his power when the quarto of 1737 was in the press. He transcribed the original at the time it was written, and sent a copy to Lord Oxford, ostensibly to let him see the way in which he was mentioned in it, but partly, perhaps, because the poet thought well of the production.[140] This letter of December, 1725, reappears in tho quarto of 1741, with the addition for the first time of a postscript by Bolingbroke. A copy of the entire performance is among the Oxford papers, and reveals the fact that the Pope portion, and the Bolingbroke portion, are both abridged in the published version. Yet although the persons who brought out the collection of 1741, had the manuscript before them, or they could not have given Bolingbroke's share of the letter, they nevertheless, by a marvellous coincidence, print Pope's share precisely as it had been printed by Pope himself in 1737. The conclusion is irresistible that the editor of the quarto of 1737, was the editor of the collection of 1741. The postscript of Bolingbroke was not written when he was in the house with Pope, but was added subsequently when he got back to Dawley,[141] and its omission from the volume of 1737 was due to the circumstance, that the poet had not then received back his correspondence from Swift, and only possessed a copy of his own carefully composed essay.
