Fishing Grounds of the Gulf of Maine

Ten Acre or Nipper Ground Extends S. ½ E. from Boon Island 6 miles and E. from Isles of Shoals 7 miles. This shoal is about 1/4 mile wide and has 18 to 20 fathoms over clay and mud, the ground sloping gradually to 50 or 60 fathoms near the edge. This is a good fishing ground for cod, haddock, cusk, and pollock in the spring, while on the muddy edges hake are abundant in September.

Marks: White Hills over Boon Island on center (these cross bearings meet near the center of the ground); also, the Black Hill W. of Portsmouth over the Star Island of the Isles of Shoals leads to the small rocky shoal that is in the middle of the ground.
