[Edward Manning Ruttenber (1906)] A few Dutch names that are regarded by some as Indian, have been noticed, and also some Indian names on the Delaware River which, from the associations of that river with the history of the State, as in part one of its boundary streams, as well as the intimate associations of the names with the history of the valley of Hudson's River, become of especial interest. 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.
