THE principal commerce subsisting at Lowestoft is derived from its herring-fishery. The town most probably, received its very existence from the convenient situation of its coast for fishermen to exercise the several occupations of a life dependent on those employments; which in the more early ages, extended, very likely, to every kind of fish that the coast afforded; though now, in these more recent times, it is chiefly confined to the herring fishery. The herrings appear on the coast of Shetland in the month of June, and from thence they proceed to the coast of Scotland; but being interrupted in their passage by the Island of Great Britain, they separate into two divisions, one of which divisions, after steering west, or south west, and leaving the Isles of Orkney and Shetland on the north, pass by the western isles, and proceed to Ireland; and there receiving a second retardation, they subdivide, and one part keeps the coast and shore of Britain and passing down St. George’s Channel as far as the mouth of the Severn, where they unite again with their former friends, and the second part of the same division, who had edged off to the west and south-west, and sheering along the western shore of the coast of Ireland, and then proceeding south and south-east, were also entered into St. George’s Channel. The second part of the first division, which was separated off the north part of Scotland having directed their course to the south and south-east, entered the German ocean; and continuing their progress along the coast of Scotland, they proceed to the south, and rounding the high shore of Berwick and St. Abb’s, are not seen any more till they arrive upon the Yorkshire coast, and not in any great quantities till they appear off Yarmouth and Lowestoft; where, after continuing a few weeks, and leaving an immense quantity of spawn, they pass through the German ocean, and entering the straights of Dover continue to proceed along the coasts of Sussex, Hampshire, etc., to the Land’s End, where the two divisions forming a junction, they enter the vast Atlantic ocean.
