Note 214 — Chapter XIX

There is a well-defined line of demarkation between the almost uninterrupted rock wall of the north coast and the sand, which, beginning in the Old Colony, in Scituate, constitutes Cape Cod; and, if we consider Nantucket, Martha's Vineyard, and Long Island as having at some period formed the exterior shores, the almost unbroken belt of sand continues to Florida. This line is so little imaginary that it is plain to see where granite gives place to sand; and it is sufficiently curious to arrest the attention even of the unscientific explorer.
