dangerous of these "blows" come out of the mountain to the north and
northwest of the gulf. Thus, in addition to the uncertainty of an
opportunity to set gear when once upon the fishing grounds, the winter
fishing here is not without its element of serious danger. While the ice
crop in northern New England never fails, yet, perhaps because of the
strong tidal currents of these waters, the principal harbors rarely are
closed by ice, or, if closed, for but a few days only.

While the summers are fairly mild and in certain parts of them even
extremely hot, fogs are heavy and virtually continuous during the "dog
days" (July 20 to September 1). when southerly and south-westerly
breezes bring the warm moist air from the Gulf Stream into the cooler
currents from the land. The fogs of Fundy are especially noted, even in
these waters. During the summer seasons winds from the east and north
bring the only clear weather experienced in the outer chain of fishing
grounds.

The main body of the gulf lies approximately between 42° and 45° north
latitude. It is in form like a deep bowl whose outer rim is made by
Georges Bank and Browns Bank, with a narrow, deep-water spillway
between: its area is half encircled in the arms of the mainland, two
conspicuous headlands reaching bodily seaward to mark its wide entrance
at the opposite sides--Cape Cod, Mass. [7] on the western side, and Cape
Sable, [8] Nova Scotia, on the eastern flank, distant from each other
about 230 miles. These two capes range with each other about ENE. and
WSW, thus matching alike the general trend of the coast line, of the
island chains and of the offshore ledges within this area.

From a base line connecting these outposts of the gulf the distance to
the Maine coast opposite averages about 120 miles. From Cape Sable, at
