The perpetrator of the forged letter and the purpose in sending it to the Queen have never been discovered, but the irritation arising from it might well have destroyed Swift's interest in Mrs. Barber's subscription list. He apparently recognized, however, that she was innocent of offense and continued his efforts in her behalf. Dr. Arbuthnot writes that he has shown "as much civility as he could" to Mrs. Barber.[320] Gay has "made a visit to Mrs. Barber."[321] Lady Betty Germain says Mrs. Barber "goes on in her subscription very well."[322] But the list was incomplete by the summer of 1732 and dragged slowly on till 1734 in spite of the aid of Mr. Barber, Lord Mayor of London, Mrs. Worsley, Mrs. Cæsar, Mrs. Conduitt, Miss Kelly, Lord Carteret, Lord Orrery, and the Duchess of Queensberry, all of whom in response to applications from Swift wrote to him concerning the progress of Mrs. Barber's affairs. In 1733 Mrs. Conduitt wrote that "the town had already been so long invited into the subscription that most people had already refused or accepted."[323] It was not till 1734 that the list was considered long enough to make publication safe. Swift crowned his service by writing a dedicatory letter to Lord Orrery. In this letter he spoke of Mrs. Barber as follows: She desireth your protection on account of her wit and good sense, as well as of her humility, her gratitude, and many other virtues. I have read most of her poems; and believe your Lordship will observe, that they generally contain something new and useful, tending to the reproof of some vice or folly, or recommending some virtue. She never writes on a subject with general unconnected topics, but always with a scheme and method driving to some particular end: wherein many writers in verse, and of some distinction, are so often known to fail. In short, she seemeth to have a true poetical genius, better cultivated than could be expected, either from her sex, or the scene she hath acted in, as the wife of a citizen. Yet I am assured, that no woman was ever more useful to her husband in the way of his business. Poetry hath only been her favorite amusement; for which she hath one qualification that I wish all good poets possess'd a share of; I mean, that she is ready to take advice, and submit to have her verse corrected, by those who are generally allow'd to be the best judges.[324] But for the persistent efforts of Swift the subscription would never have been completed. Yet Mrs. Barber had gained incidentally such a retinue of supporting friends that her poems were republished in 1735 and 1736. There was apparently a touch of personal venom in the passage where Mrs. Pilkington chronicles the generous aid given Mrs. Barber and emphasizes the final small success of the poems:
