Texts of traditional ballads have been communicated to me in America by Mr W. W. Newell, of New York, who is soon to give us an interesting collection of Children's Games traditional in America; by Dr Huntington, Bishop of Central New York; Mr G. C. Mahon, of Ann Arbor, Michigan; Miss Margaret Reburn, of New Albion, Iowa; Miss Perine, of Baltimore; Mrs Augustus Lowell, Mrs L. F. Wesselhoeft, Mrs. Edward Atkinson, of Boston; Mrs Cushing, of Cambridge; Miss Ellen Marston, of New Bedford; Mrs Moncrieff, of London, Ontario. Acknowledgments not well despatched in a phrase are due to many others who have promoted my objects: to Mr Furnivall, for doing for me everything which I could have done for myself had I lived in England; to that master of old songs and music, Mr William Chappell, very specially; to Mr J. Payne Collier; Mr Norval Clyne, of Aberdeen; Mr Alexander Young, of Glasgow; Mr Arthur Laurenson, of Lerwick, Shetland; Mr J. Burrell Curtis, of Edinburgh; Dr Vigfusson, of Oxford; Professor Edward Arber, of Birmingham; the Rev. J. Percival, Mr Francis Fry, Mr J. F. Nicholls, of Bristol; Professor George Stephens, of Copenhagen; Mr R. Bergström, of the Royal Library, Stockholm; Mr W. R. S. Ralston, Mr William Henry Husk, Miss Lucy Toulmin Smith, Mr A. F. Murison, of London; Professor Sophocles; Mr W. G. Medlicott, of Longmeadow; to Mr M. Heilprin, of New York, Mme de Maltchycé, of Boston, and Rabbi Dr Cohn, for indispensable translations from Polish and Hungarian; to Mr James Russell Lowell, Minister of the United States at London; to Professor Charles Eliot Norton, for such "pains and benefits" as I could ask only of a life-long friend. In the editing of these ballads I have closely followed the plan of Grundtvig's Old Popular Ballads of Denmark, a work which will be prized highest by those who have used it most, and which leaves nothing to be desired but its completion. The author is as much at home in English as in Danish tradition, and whenever he takes up a ballad which is common to both nations nothing remains to be done but to supply what has come to light since the time of his writing. But besides the assistance which I have derived from his book, I have enjoyed the advantage of Professor Grundtvig's criticism and advice, and have received from him unprinted Danish texts, and other aid in many ways. Such further explanations as to the plan and conduct of the work as may be desirable can be more conveniently given by and by. I may say here that textual points which may seem to be neglected will be considered in an intended Glossary, with which will be given a full account of Sources, and such indexes of Titles and Matters as will make it easy to find everything that the book may contain.
