The Sankaty Head ground is about 20 miles long by about 8 miles wide, stretching from 55 miles SE. from Highland Light to 78 miles SE. by S 1/2 S. from the same point (the bottom of the Channel), and is bounded on all sides by pieces of bottom less favorable to the operation of the otter trawl because of the presence of rocks, sponges, or other obstacles, which interfere with the free passage of the net over the bottom but offer less trouble to the line-trawl fishermen. A good spring haddock ground lies ESE. 65 miles from the Highlands in 70 fathoms. best in March and April. As the cold weather advances the fish move away in great part from these grounds, going into the deeper water, the catches of the fall and winter months being taken mainly In depths of from 60 to 100 fathoms. At this season and in these depths the vicinity of the Corner of the Channel, Clarks Side. and the area N and W of the Cultivator usually have a good winter school of haddock. This has been particularly large during the past three year. (1923 to 1925). Thus, it may be seen that the Channel is an important ground during most of the year. The figures of the catch from Clarks Bank have been shown together with those of Georges Bank. of which, in fact, this area is a part. The larger part of the sail fleet is found fishing on the grounds of the eastern side of the Channel and of the western edge of Georges Bank, in part to escape the damage that the otter trawlers cause to them in dragging away their gear. It is often impossible for these steamers to avoid some damage of this kind: especially is this the case in the thick weather so prevalent oil Georges. In the summer months of the "mackerel years" a large catch of this species is taken from the waters of the Channel. St. Georges Bank, more generally known as Georges Bank. [15] This is by far the largest and most important fishing ground near the coast of the United States and is second to none in the western Atlantic except the Grand Bank of Newfoundland. It lies eastward of Cape Cod and Nantucket Shoals and is apparently an extension of the latter, since the water is no deeper between the southern part of the shoals and the western part of the bank than in many places upon it. Its southern limit, as shown on the chart, is 40 deg. 40' north latitude, though the 50-fathom line extends 7 miles farther south. The southern limit, therefore, may be considered to be about 40 deg. 30' and the northern as 42 deg. 08' north latitude. The eastern part is in about 66 deg. and the western in about 69 deg. west longitude. The greatest length from the northeastern to the southwestern extremity is about 150 miles; the greatest width, N. and S., about 98 miles, according to the charts of the Coast Survey.
