The deception which Pope practised was never suspected till it was revealed by his correspondence with Lord Oxford, which has hitherto remained in manuscript. The repetition of the attempt on a more elaborate scale was less successful, and it has always been believed by the immense majority of inquirers that the promulgation of the collection of 1735, which the poet vehemently denounced as an act of intolerable treachery, was from first to last his own deed. "It seems," says Johnson, "that Pope being desirous of printing his letters, and not knowing how to do, without imputation of vanity, what has in this country been done very rarely, contrived an appearance of compulsion, that when he could complain that his letters were surreptitiously published, he might decently and defensively publish them himself."[23] Fresh facts have rendered the evidence against him stronger than ever, and the whole derives increased force from the information we now possess that he had previously had recourse to a kindred falsehood. In the first case he made a tool of a friend; in the second, he varied his plan, and made a tool of an enemy.
Pope tells us, in the preface to the authorised edition of his correspondence, which he brought out in quarto in 1737, that his disgust at the publication of his letters to Cromwell, and "the apprehension of more treatment of the same kind, put him upon recalling as many as he could from those who he imagined had kept any."[24] He applied to his friend Caryll, in December, 1726, to surrender his collection; and, on renewing the request a few days later, he added, "I have desired the same thing of Mrs. Blount, with whose late worthy husband I entertained so long a correspondence, and of all others." It was more than two years before Caryll could be induced to comply with the demand, and it would seem that Mrs. Blount was little less backward; for, on November 28, 1729, Pope wrote to Swift, "I _lately_ received from the widow of one dead correspondent, and the father of another,[25] several of my own letters of about fifteen and twenty years old." When the poet had gleaned together all the letters he could extort, "he immediately," he says, "lessened the number by burning three parts in four of them: the rest he spared, not in any preference of their style or writing, but merely as they preserved the memory of some friendships which will ever be dear to him, or set in a true light some matters of fact from which the scribblers of the time had taken occasion to asperse either his friends or himself." He was not more anxious to destroy the three parts than to secure the fourth from destruction. "He laid by the originals together with those of his correspondents, and caused a copy to be taken to deposit in the library of a noble friend, that in case either of the revival of slanders, or the publication of surreptitious letters during his life or after, a proper use might be made of them."[26] The noble friend was Lord Oxford, and the request to be allowed to place the letters in his library was made by Pope in September, 1729, when he stated that "he had had it at heart for half a year and more." Upon obtaining Lord Oxford's consent, he had the correspondence transcribed under his own inspection; and on October 16 he says, "I am causing the manuscripts to be fairly written, and hope at your lordship's return to be the presenter of them in person." By his own avowal he had carefully culled his letters, had prepared the selected portions for some public purpose, and had taken the unusual precaution of preserving them in duplicate. The end which he declared they were intended to serve was a palpable pretence. He never specified any slanders they refuted, and he could have had little idea of employing them to test the truth of surreptitious letters when he began by burning three parts of the collection, and only retained a fourth. The manifest fact was, that, while he was desirous of consigning to oblivion those portions of his correspondence which would not add to his reputation, he was eager to circulate the picked specimens which he imagined would promote his fame.
