In the arrangement of names geographical association has been adopted in preference to the alphabetical, the latter being supplied by index. This arrangement seems to bring together dialectic groups more satisfactorily. That there were many variations in the dialects spoken in the valley of Hudson's River no one will deny, but it may be asserted with confidence that the difference between the German and the English alphabets in renderings is more marked than differences in dialects. In so far as the names have been brought together they form the only key to the dialects which were spoken in the valley. Their grammatical treatment is the work of skilled philologists. Credit has been given for interpretations where the authors were known, and especially to the late eminent Algonquian authority, J. Hammond Trumbull. Special acknowledgment of valuable assistance is made to the late Dr. D. G. Brinton, of Philadelphia; to the late Horatio Hale, M. A., of Clinton, Ontario, Canada; to the late Prof. J. W. Powell, of the Bureau of Ethnology, Washington, D. C, and his successor, William H. Holmes, and their co-laborers, Dr. Albert S. Gatschet and J. B. N. Hewitt, and to Mr. William R. Gerard, of New York. The compilation of names and the ascertaining of their locatives and probable meanings has interested me. Where those names have been preserved in place they are certain descriptive landmarks above all others. The results of my amateur labors may be useful to others in the same field of inquiry as well as to professional linguists. Primarily the work was not undertaken with a view to publication. Gentlemen of the New York Historical Association, with a view to preserve what has been done, and which may never be again undertaken, have asked the manuscript for publication, and it has been given to them for that purpose.
