Footprints of the Red Men / Indian geographical names in the valley of Hudson's river, the valley of the Mohawk, and on the Delaware: their location and the probable meaning of some of them.

The work compiles and analyzes Indigenous place-names across the Hudson, Mohawk, and Delaware valleys, identifying original locations, mapping them, and proposing probable meanings based on local physical features. It explains methodological issues in transmission and orthography, compares Algonquian and Iroquoian dialect forms (including Unami, Minsi and Mohawk), and notes how names were sometimes extended or transferred by settlers. Entries translate root elements for common landscape features—hills, streams, stones, meadows—and discuss locative suffixes, polysynthetic structure, and the limits of certainty while citing documentary locatives, missionary vocabularies, and comparative linguistic evidence.
