From the JOURNAL OF MARTIN PRING (1603):
SOURCE: The Voyage of Martin Pring, 1603 as archived at the Wisconsin Historical Society. Although Pring’s locations are a bit hard to nail down, the editor of the above transcription supposes the “FOUR INLETS” are the Saco, Kennebunk, York, and Piscataqua Rivers.
