The letter urging Curll anew to make a false statement of the means by which he obtained the correspondence, was received by him on the morning of May 15. "I am," he said, in his reply, "just again going to the Lords to finish Pope."[63] He verified his boast. In place of adopting the advice of P. T., he showed the letter which contained it.[64] Pope's double dealing had been strongly suspected on the previous day, when it was discovered that the copies seized had been altered in anticipation of the charge he preferred. There was now a second coincidence to connect him with the plot. The letter produced by Curll revealed that the correspondence had been taken from the archives of Lord Oxford, and that the story Pope had volunteered to Caryll, and which he undoubtedly reiterated to his friends among the Lords, was not only an invention to conceal the truth, but the same invention which P. T. exhorted the bookseller to adopt. Some step was necessary to save the poet from discomfiture. He therefore put forth an advertisement in the "Daily Post-boy," acknowledging, what he was no longer able to deny, that "some of the letters could only be procured from his own library, or that of a noble Lord," and promising twenty guineas to either Smythe or P. T. if they would "discover the whole affair," and forty guineas if they "could prove that they had acted by the direction of any other person."[65] This was an old device of the poet. To escape from the obloquy he incurred by an impious and indecent parody of the First Psalm, he inserted an advertisement in the "Postman," offering a reward of three guineas for the discovery of the person who sent it to the press. The publisher, Mrs. Burleigh, declared that she possessed the manuscript in his own handwriting, and expressed her readiness to produce it, but he never ventured to accept the challenge or to contradict her assertion.[66] Pope did not acknowledge that the essence of a falsehood was in the deceit. "If you have seen a late advertisement," he wrote to Miss Blount, August 7, 1716, alluding probably to this transaction, "you will know that I have not told a lie, which we both abominate, but equivocated pretty genteelly." Without in strict language disclaiming the authorship, he intended that the reader should understand it as a disclaimer. His advertisement respecting the letters was a kindred case. He meant it to be received as a denial of all connivance at the publication of his correspondence, and in strict language he denied nothing. He said that the book was printed by P. T., in combination with Smythe, which was equally true, if P. T. was Pope. He could use the phrase "_some_ of the letters," when driven to confess that they were procured from the library of Lord Oxford, because the volume contained the Cromwell and Wycherley letters, which had been printed before. He could hold out the bait of rewards to himself without any risk of
