Definition of "inshore"

My hopes wa'n't disappointed. I never saw clams thicker than they was along them inshore flats. I filled my dreener in no time, and then it come to me that 'twouldn't be a bad idee to get a lot more, take 'em with me to Wellmouth, and peddle 'em out. Clams was fairly scarce over that side of the bay and ought to fetch a fair price.

1913, Joseph C. Lincoln, chapter 3, in Mr. Pratt's Patients

The sunset's roses faint and fain decline.Inshore the still sea shimmers scale on scale,Like an enormous coat of magic mail —Sheet silver shot with tremulous opaline.

1875, William Henley, Notes on the Firth

It is now believed that many species of sharks come inshore at night to feed and, therefore, that attacks made during the day are not related to the feeding process.
