Isles of Shoals. These islands, 8 miles from
the mouth of Portsmouth harbor, N. H., are seven
in number, viz.: Hog, Smutty Nose, Star, Duck,
White, Malaga, and Londoner Islands. Hog
contains 350 acres of rock, and its greatest ele-
vation is 57 feet above high water mark. Smutty
Nose contains about 250 acres of rock and soil —
greatest elevation 45 feet. Star Island contains
about 180 acres of rock and soil, and its height
is 55 feet. These islands, as a town, are called
Gosport. Star and Smutty Nose are inhabited
by fishermen, who carry on considerable business
in their way, supplying Portsmouth and the
neighboring towns with fresh fish, and sending
large quantities of cured fish to Boston and other
places. The celebrated dun fish are found here,
which have heretofore been considered a distinct
species of the cod. They differ, however, from
the common cod only in the circumstance of
their being caught and cured in winter. Star
Island and Smutty Nose are connected by a sea
wall, built at the expense of government, for the
purpose of breaking a strong S. E. current pass- I
ing between them, and forming a safe anchorage
on the N. W. side of it. These objects have been
attained, and the miniature fleet of the shoalers,
riding at anchor in this artificial harbor, is no un-
pleasant sight. Smutty Nose and Malaga are
connected by a sea wall, built at the expense of
Mr. Haley, ¹¹ the King of the Shoals." This
wall, 14 rods in length, 13 feet in height, and from
20 to 30 feet in width, effectually secures Haley's
Inlet and Wharf from the easterly storms, although
the waves not unfrequently break over it in a
severe storm. There are a few spots of dry soil
upon them under cultivation. The Shoals are a
pleasant resort for water parties, and their de-
lightful, bracing air cannot be otherwise than
advantageous to those who are in want of pure
sea breezes. See Hayward's New England Gaz-
etteer.
