Another big ridge, paralleling the 100-fathom curve of Georges Bank at about 20 miles N. of it, lies SE by S from the buoy on Cashes Ledge, forty miles to its center; SE by S 110 miles from Portland Lightship; ESE 92 miles from Cape Ann to its western end, and E. by S. ½ S. from the ship at Boston 100 miles. This ridge also is of somewhat indefinite area, being perhaps 20 miles long in an ESE by WNW direction by 1½ to three miles wide. Apparently depths are fairly uniform from 85 to 95 fathoms, the bottom of the ridge being of coarse black sand and having blue mud in the deeper area around it. This is said to be a good cod and cusk ground the year round.
John Dyers Ridge. This lies 14 miles S. by E. from Toothakers Ridge, 40 miles S. by E. from Monhegan Island, and 7 miles NE. from Cashes Bank. It is about 5 miles long by 2 miles wide, lying in an ENE. and WSW. direction. The water is shoalest on the western edge, where are from 45 to 50 fathoms over a sharp, pebbly bottom; thence the ground slopes to the NE. into 75 and 80 fathoms over a hard, gravelly, and muddy bottom, in all other directions falling off sharply to 90 and 100 fathom soundings over a muddy bottom.
This is essentially a cod ground for the entire year, the species being most abundant from May 1 to November. It is a cusk ground all the year on the hard bottom of the deeper parts, March and April showing the largest schools. Hake also are abundant in 70 fathoms and deeper on the mud in summer and fall.
Fifty-five Fathom Bunch. West of Cashes Bank is a rocky ridge extending ENE. and WSW. about 4 miles and having a width of about 1 mile. This is mainly a cod ground, the seasons for the species being as on Cashes Bank.
Fippenies Bank. This consists of two shoals averaging 80 fathoms in depth with a channel of 90 fathoms between them. These run NE. and SW., the eastern shoal about 8 miles long by 1 mile wide, the western about half as large. Fippenies bears E. 1/4 S. from Thacher Island, distant 61 miles; from Portland Lightship, SE. by S. ½ S, 57 miles to the western point of the northern shoal in 35 fathoms. The bank is nearly 10 miles long NE. and SW. and averages 4½ miles wide. The bottom is of gravel, pebbles, and clay, having depths over much of the shoal of about 30 fathoms but also from 36 to 60 fathoms. It is fished by the shore fleet in the spring and early summer. The fish and seasons are as on Cashes Bank. Formerly twice as many haddock were taken here as on Cashes or on Platts Bank, but this has changed in recent years. Halibut are taken here in fair numbers in 45 to 55 fathom depths in June, July, and August on the "black gravel" of the southern and western edge. The "white gravel" on the north shoal is of little account as a fishing ground, since it is composed mostly of the shells of dead scallops.
The Ridge (on the southern part of Fippenies). This is SSE. from the light-ship at Portland 75 miles and has a bottom of yellow mud and pebbles and depths of 75 to 95 fathoms. Cod are present here in December and January; cusk the year around, but most numerous in February and March; haddock in December and January; hake in September and October. The length of this bank is from 4 to 5 miles and the width somewhat less than 2 miles. It lies in an ENE. and WSW. direction.
Maurice Lubee's Ground. This lies outside of New Ledge (Platts Bank) 47 miles SSE. from the lightship at Portland. Extending in an ENE. and WSW. direction, its boundaries are somewhat indefinite. It is perhaps 8 miles long by 3 miles wide and has depths from 95 to 110 fathoms over a bottom consisting mostly of mud.
Cusk are plentiful here in the spring, with a few in the fall. Cod are taken all the year around, the Spring school being the largest. Hake are most numerous In the spring and fall months, and haddock are not common but are most numerous in winter.
Apparently the abundance of cod on this ground is due to the great quantity of shrimps and soft-shelled crabs found on the muddy bottom and on the rocks that compose this ground. There seem to be many of these deep-water grounds between and about the shoaler grounds, as near Cashes, Fippenies, and Jeffreys, which apparently serve as fairways over which the schools of hake, cod, and cusk, move from Georges Bank into the Gulf of Maine in the spring of the year.
Harvey Blacks Ridge. This is SE. ½ S. from the lightship off Portland, distant 42 miles, and SE. from New Ledge, distant 8 miles. From Glovers Rock, off Small Point, Me. this ridge lies SE. by S. ½ S. 41 miles. It extends in an ENE. and WSW. direction about 4 miles long by I mile wide. Depths average 70 to 100 fathoms over a bottom of yellow clay and gravel. Cod are taken here all the year. Haddock are found in the deep water in the spring: cusk all the year in deep water, together with hake in summer, also on the muddy bottom in deep water. Pollock and other surface-schooling fish are found here in their proper season.
