The selections from the above American authors are used by special arrangements with the firms mentioned, who are the only authorized publishers of their works. Many other poems used have been found in papers or other places which gave no indication of the original source. In spite of much effort to trace these things it is quite likely we have failed in some cases to give due credit or obtain the usual permission; and we hope that if such omissions, due to ignorance or inadvertence, are noticed they will be pardoned. Many unknown writers have left behind them some things of value, but their names have become detached from them or perhaps never were appended. Many volumes consulted have been long out of print. We are glad to record our large indebtedness to the custodians of the Boston, Cambridge, Malden, Natick, Brookline, Jamaica Plain, Somerville, and Newton Public Libraries, the Boston Athenaeum, the Congregational Library, the General Theological Library, and the Library of Harvard College, for free access to their treasures. By far the greater part of the contents are from British and other foreign authors, such as William Wordsworth, Alfred Tennyson, Robert Browning, Elizabeth Barrett Browning, Dinah Maria Mulock Craik, Mrs. S. F. Adams, Anna Letitia Barbauld, Mrs. Charles, Frances Ridley Havergal, Anna Letitia Waring, Jean Ingelow, Adelaide Anne Procter, Mme. Guyon, Theodore Monod, Matthew Arnold, Edwin Arnold, William Shakespeare, John Milton, George Gordon Byron, Robert Burns, William Cowper, George Herbert, Robert Herrick, Francis Quarles, Frederick W.

Kirke White, Horatius Bonar, James Montgomery, Charles Wesley, Richard Baxter, Norman Macleod, George Heber, Richard Chenevix Trench, Henry Alford, Charles Mackay, Gerald Massey, Alfred Austin, Robert Louis Stevenson, Arthur Hugh Clough, Henry Burton, Samuel Taylor Coleridge, Hartley Coleridge, Joseph Anstice, George Macdonald, Robert Leighton, John Henry Newman, John Sterling, Edward H. Bickersteth, Dante Gabriel Rossetti, and many others. Of German authors there are not a few, including Johann W. von Goethe, Johann C. F. Schiller, George A. Neumarck, Paul Gerhardt, Benjamin Schmolke, S. C. Schoener, Scheffler, Karl Rudolf Hagenbach, S. Rodigast, Novalis, Wolfgang C. Dessler, L. Gedicke, Martin Luther, and Johann G. von Herder.
