size or the abundance of its
product. It lies S. of Cape Breton Island and the eastern part of Nova
Scotia between the parallels of 42 deg. 55' and 44 deg. 46' north
latitude and the meridians of 59 deg.04' and 62 deg. 35' west longitude.
It has a length of 156 miles and a width, including the Middle Ground,
of 76 miles. It is about 420 miles E. 1/2 S. from Boston to the
southwestern edge, which means about 48 hours' steaming for the
otter-trawl fleet.
The general contour of the bank within the 65-fathom line, as laid down
on the Admiralty chart, approaches somewhat a very elongated ellipse,
the longer axis running NE. by E. and SW. by W.; but over a broad area
to eastward of the center of the bank, soundings of less than 50 fathoms
connect it directly with the Middle Ground, which we have here included
in the some bank. The total extent of the bank thus defined is about
7,000 square geographical miles. Off its eastern end lies Banquereau
(the Quereau of the fishermen) with The Gully between, and a short
distance of the western edge are the La Have Ridges.
The depths off the southern edge of the bank increase rapidly from 80 to
700, 1,200, and even 1,400 fathoms. At the eastern end is Sable Island,
[16] "graveyard of ships", a long, narrow, crescent-shaped elevation
seemingly lessening in area each year, formed entirely of sand that has
been blown Into innumerable hummocks and dunes. Off both ends of the
island are long and dangerous sand bars. The length of the island is 20
miles; its greatest width is about 1 1/2 miles. It is said that the
Northwest Light has been moved three times due to the fact that the
western end of the island has been literally blown away. It lies in an
E. and W. direction, and the depth of water over the bars for a distance
of 7 to 10 miles out does not exceed 2 fathoms, and even 10 miles
farther out the depths do not exceed 10 to 11 fathoms. Within recent
years fishermen have reported the appearance of a sand shoal about 5 or
6 miles SE. from the Northeast Light. This is said to appear at low
water.
In general, the bank slopes S. and W. from the island, depths ranging
from 18 to 60 fathoms. The bottom is mostly sandy with patches of gravel
and pebbles. Currents are sometimes very strong about Sable Island and
are somewhat irregular; apparently they are much influenced by the
winds. On the other parts of the bank usually there is but little
current, whatever there is usually tending towa
