Fishing Grounds of the Gulf of Maine.

Inner Horse Reef This reef lies SE. ¾ E 1½ miles from the eastern ear of isle au Haute. There is a shoal here of 25 fathoms about 1/8 mile in diameter. From this the water gradually deepens to NE. for ½ mile, where it drops off into the mud. Depths on this northeast portion are about 35 fathoms. The bottom is of pebbles and gravel.

In spring and fall this is a good cod ground. Hake are found close to the edge in summer. Fishing is by small craft, generally, using trawl and handline. It is a good lobster ground.

Marks: Bring Blue Hill Mountain in the saddle of White Horse; Brimstone showing between Western Ear and Isle au Haute.
