Pope stated in his advertisement, that along with his correspondence with the Bishop of Rochester he should publish such of the letters as were genuine from the surreptitious volume, and added, that the work would be printed "with all convenient speed."[102] But speed was not convenient. The project slept till March 26, 1736, when he writes to Fortescue, "Your too partial mention of the book of letters, with all its faults and follies, which Curll printed and spared not (nor yet will spare, for he has published a fourth sham volume yesterday), makes me think it may not be amiss to send you--what I know you will be much more pleased with than I can be--a proposal for a correct edition of them, which at last I find must be offered, since people have misunderstood an advertisement I printed some time ago, merely to put some stop to that rascal's books, as a promise that I would publish such a book." His excuse for the delay in redeeming his pledge of supplying an authentic edition, is a curious instance of the absurdity to which a man of genius may be reduced, when, unable to divulge his true reasons, he has recourse to invention. "People" could not have "_misunderstood_" the advertisement as "a promise that he would publish such a book," for the promise was distinct, and there was no room left for misunderstanding in the matter. But if we allow that an advertisement in the newspapers, asserting that he was under a necessity of putting out a genuine edition, which would be printed with all convenient speed, was only designed to be read as a threat for the purpose of stopping Curll's trade, it is plain that Curll must have become acquainted with an interpretation which was apparent to the rest of the world, and would have paid no attention to a menace that was not intended to be executed. Unless Pope desired that the public should believe he was serious, the whole proceeding was objectless. He was long in learning the misconstruction which had been put upon his words. While the announcement was fresh, and likely to have been a topic of conversation, he remained completely passive, and it was not till after an interval of more than eight months that he discovered he was supposed to have given a pledge, and must immediately redeem it. He had forgotten that he had betrayed to Fortescue that he was in earnest at the time the advertisement appeared. On August 2, 1735, a fortnight after it was issued, Pope wrote to him, and asked to have back his letters; "for," said he, "I find my collection, such as it is, must be hastened, or will not be so effectual." It had not yet occurred to him to maintain that his promised publication was a feint. The true cause of his procrastination has been suggested by the critic in the Athenæum. He had distributed portions of his extensive correspondence with Caryll among other groups, and addressed several of the letters to men of higher position or greater fame. He must have rejected the fictitious compound from his genuine edition, or waited till Caryll, who was sinking with age and illness, was in his grave. The latter was the course which Pope preferred. His friend was no doubt dying at the close of March, 1736, and on the 6th of April he expired. With him disappeared the sole difficulty which stood in the way of the new edition, and the poet from that moment was active in its prosecution.
