Sea monster is reported off the coast of Boston.

Two sentries report seeing a sea serpent swim past Castle Island. Their superior, Col. Harris, verifies the sighting, as does resident James Prince, who writes, “His head appeared about three feet out of the water; I counted thirteen bunches on his back – my family thought there were fifteen – he passed three times at a moderate rate across the bay. . . I had seven distinct views of him from the long beach so called, and at some of them the animal was not more than a hundred yards distance.”
