The Inner Fall lies Se. 1/2 S. from Monhegan Island, 21 1/2 miles, west of Newfound 6 miles, and S. by W 1/2 W. from Matinicus Rock 17 miles.  The Outer Fall lies S. 1/2 E. from Matinicus Rock 21 miles.  These both have hard sharp bottoms, which are good cod and cusk grounds in the spring.  The gravelly bottom, both on the Inner Fall and on the Outer Fall, often holds halibut in the spring and early summer (May 1 to July 15) in depths of from 35 to 60 fathoms.  The fishing ground of the Inner Fall is somewhat difficult to find, the best portions lying in a narrow strip about 6 miles long by something less than 1 mile wide along the northwestern edge of the bank.

Soundings ranging from 35 to 55 fathoms over the main body of the bank drop suddenly to 85 and even 94 on the edges.  The average depth is about 45 fathoms over a rocky bottom, with good cod fishing in summer and cusk on the hard bottom of the deeper water.  Haddock usually are abundant on this bank in winter.  Along the northern edge of Jeffreys Bank, between the Inner Fall and the Outer Fall, in an average depth of 40 fathoms, cod and halibut are taken in spring and summer.  The extreme southern part of the bank is also a fairly good cod ground, while halibut occur in fair numbers in summer.  Depths here are from 38 to 45 fathoms over rocks and gravel.

A small circular piece of ground rises about 2 miles W. of the bank, lying between it and Toothaker Ridge.  This is about 2 miles across and has depths averaging 50 fathoms over a rocky bottom.  This spot is a good summer cod ground.

Toothaker Ridge.  This bank is 26 miles S. 1/2 E. from Monhegan and lies in an ENE. and WSW. direction.  There seem to be two ridges here, the larger being about 5 or 6 miles long by about 1 1/2 miles wide.  This inner ridge has a shoal of 35 fathoms on the western end, from which it deepens eastward to about 45 fathoms, which is the general depth elsewhere on this piece of ground.

The outer ridge parallels the inner at about 1 1/2 miles distance and there is a deep, narrow gully between.  It apparently has about half the area of the other.  This smaller ridge has a 45-fathom shoal of rocks on the western end, deepening the water, like the other, to the eastward to 75 and 80 fathoms over a broken rocky bottom and 90 fathoms on hard mud.  This is an all-the-year cusk ground.  A few cod are present all the year. but this species is most abundant here and on the other ridge in the spring and through June.  Hake occur on the muddy ground in summer and fall.

On both shoals are abundant growths of “lemons” and like species of fish food, and they are good “hand-line spots” over their rocky bottoms.  Fishing on both is said to be at its best in the spring and in June, the species taken being cod, cusk, pollock, and hake.  As before stated, these are year-around cod and cusk ground, pollock and hake being present in summer and fall, the latter species over the muddy ground.  These grounds have been thought to lie too rough for trawling.  But occasional good fares are taken on them by this method.
