21. _A Collection of Psalms and Hymns for the Sanctuary_—Boston, 1845. Edited by Rev. George E. Ellis (1814-1894) for use in the Harvard Church in Charlestown, Mass., of which he was then minister. It contains 658 hymns and psalms, and is based on _Greenwood’s Collection_ (13) and _The Springfield Collection_ (14). A Selection from the Psalms, apparently intended for responsive reading, is bound up with the hymn-book, of which it is an unusual feature. 22. _Hymns for Public Worship_—Boston, 1845. Edited by Rev. George W. Briggs (1810-1895), minister of the First Church at Plymouth, Mass. (1838-1852). The book contains 601 hymns; no musical directions beyond indication of metres. There is a strong emphasis on hymns of the inner life, the compiler having sought “to bring together the most fervent expressions of a profound spiritual life,” many of which “have never been in familiar use in Unitarian churches.” 23. _Service Book: for the Church of the Saviour, with a Collection of Psalms and Hymns for Christian Worship_—Boston, 1845. Edited by Rev. Robert Cassie Waterston (1812-1893), minister of the Church of the Saviour, Boston. _The Collection of Psalms and Hymns_ bound up with the services is _Greenwood’s Collection_ (13) with a supplement of 116 hymns selected by Waterston, so that the book is more accurately described as one of the editions of Greenwood than as an independent publication. The supplement, however, is notable for the high proportion of good new hymns, not available when _Greenwood’s Collection_ first appeared. Among them are hymns by Samuel F. Smith, G. W. Doane, the early and mid-century Unitarian writers, and some taken from Breviary sources. No musical instructions beyond indication of the metres. 24. _A Book of Hymns for public and private devotion_—Cambridge: Metcalf & Company, printers to the University. 1846. Edited by Samuel Longfellow (1819-1892) and Samuel Johnson (1822-1882). The editors were, at the time, students in the Harvard Divinity School (class of 1846), and the book “grew out of an offer to provide a new book for a minister who found even the recent ones too antiquated.” It was marked by poetic excellence and freshness, and introduced to American use “Lead, Kindly Light,” and hymns by Whittier, Longfellow, Lowell, Jones Very, Mrs. Stowe and others, besides hymns by the editors themselves. First used in Church of the Unity, Worcester, Mass., of which Edward Everett Hale was minister; then in the Music Hall congregation of Theodore Parker, who is said, on receiving a copy, to have remarked, “I see we have a new book of Sams.” It ran to a twelfth edition in two years, but its greatest influence was as a source-book for later editors. A somewhat enlarged edition appeared in 1848. 25. _Hymns of the Sanctuary_—Boston, 1849.
