[10] Although Lewis Tappan took a zealous interest in the formation of the Unitarian Association, as he did in all Unitarian activities of the time, in the autumn of 1827 he withdrew from the Unitarian fellowship, and joined the orthodox Congregationalist. In a letter addressed to a Unitarian minister he explained his reasons for so doing. This letter circulated for some time in manuscript, and in 1828 was printed in a pamphlet with the title, Letter from a Gentleman in Boston to a Unitarian Clergyman of that City. Want of Piety among Unitarians, failure to sustain missionary enterprises, and the absence of a rigid business integrity he assigned as reasons for his withdrawal. This pamphlet excited much discussion, pro and con; and it was answered in a caustic review by J.P. Blanchard. [11] Moses George Thomas was a graduate of Brown and of the Harvard Divinity School, was settled in Dover, N.H., from 1829 to 1845, Broadway Church in South Boston from 1845 to 1848, New Bedford 1848 to 1854, and was subsequently minister at large in the same city. [12] In writing to Charles Briggs from Newport, under date of July 30 1836, Dr. Channing wrote, "In the pressure of subjects, when I saw you, I forgot to say to you, that I cannot accept the office with which the Unitarian Association honored me." That is the whole of what he wrote on the subject. No one else was elected to the office for year. It is evident, therefore, that his name should occupy the place of president. [13] The depositaries in Massachusetts were at Salem, Concord, Hingham, Plymouth, Yarmouth, Cambridge, Worcester, Northampton, Springfield, and Greenfield; in New Hampshire, at Concord, Portsmouth, Keene, and Amherst; in Maine, at Hallowell, Brunswick, and Eastport; and, in Connecticut, at Brooklyn. In 1828 the number had increased to twenty-five in Massachusetts, six in Maine, seven in New Hampshire, one in Rhode Island, four in New York, two in Pennsylvania, and two in Maryland. At the first annual meeting of the Unitarian Association a system of auxiliaries was recommended, which was inaugurated the next year. It was proposed to organize an auxiliary to the Association in every parish, and also in each county. These societies came rapidly into existence, were of much help to the Association in raising money and in distributing its tracts, and energetic efforts were made on the part of the officers of the Association to extend their number and influence. They continued in existence for about twenty years, and gradually disappeared. They numbered about one hundred and fifty when most prosperous.
