What the record says

NCEI’s account, from the sources it cites.

On the afternoon of the former day, the tide, then at ebb, was noticed to suddenly rise and rush up the river with great velocity to a height of from one and a half to two feet. It receded just as suddenly, leaving in several places along the banks large numbers of fish behind it. These sudden ebbs and flows were continued during that and the following day at intervals varying from 10 minutes to half an hour, the water in the river being in the meantime unusually thick and muddy, while the ocean outside was if anything smoother than usual." (reference #14280)
