Near the center of Cape Cod Bay, on a line between Race Point and Cape Cod Canal, lies a rocky elevation on which cod are taken, known as Eagle Ledge or Bay Ledge, and by Provincetown fishermen as Red Bank. It has a depth of 13 fathoms. Cape Cod Bay has a considerable Industry in flounder dragging, the fish being taken by a small type of otter trawl. South and southeast of Thacher Island from 5 to 8 miles lies a stretch of muddy bottom with patches of sand scattered over it, where a considerable amount of this method of fishing is carried on during most of the year. Old Man's Pasture. This ground is due S. from Thacher Island, SE. from Eastern Point Light. Cape Ann, and distant 5 miles. It is about 3/4 mile long, NNE. and SSW. by 1/ mile wide. The bottom is rough and rocky, with about 24 fathoms average depths. It is a cod ground for the entire year, which fish are taken by gill-netters principally in November. Pollock are taken here, also by gill-netters, from October 1 to December. Apparently there are few haddock here in the fall, but there is good fishing for these from February to April 1. It is also a lobster ground. Harts Ground. This lies S. 1/4 E. from Eastern Point Light. distant 5 1/2 miles. It is 3/4 mile long in an ENE. and WSW. direction by 1/4 mile wide, and is a small, rocky patch with a depth of 30 fathoms. It is a summer haddock ground, visited mainly by small boats. There is little or no gill netting here. Eagle Ridge, sometimes called Little Middle Bank. This ridge is 7 2/3 miles S. by W. from Eastern Point Light, Cape Ann. and 1 mile long, NE. and SW., by 1/2 mile wide. The average depths are 25 fathoms on a rocky and uneven bottom. Formerly, with Old Man's Pasture and Browns Ledge. this was considered the principal winter grounds of the cod, but not so many have been taken here at that season in recent years. Inside this area, at an average distance of 2 1/2 miles from Eastern Point Light and between bearings S. 1/2 E. and SW.. are a number of small, rocky patches having depths of from 10 to 25 fathoms--Browns Ledge, Spot of Rocks, Saturday Night Ledge, and Burnhams Rocks; SW 1/2 W. from Saturday Night Ledge, 6 miles, lies Old Tillie. Farther in are two shoal spots bearing nearly west from Eastern Point. one at 3/4 mile and the other at 2 miles distance, each having 11 fathoms. The first is called Eleven Fathom Ground. the second, Kettle Island Ledge. This latter lies 1/2 mile SE. of Kettle Island. These are cod grounds in winter and haddock grounds in summer. Gill-netters operate from Kettle Island to Halfway Rock and Italian boats trawl at all seasons off The Graves.
