We believe, however, it is now in contemplation to go to work upon a large scale in those waters, having screw-steamers to collect the produce, and bring it to Milford Haven alive in wells, from which port it would come, _viâ_ the South Wales and Great Western Railways, to Billingsgate, within twenty-four hours after it was caught. The value of screw steamers having capacious wells has been fully tested by Mr. Howard, of Manningtree, Essex, who fitted an engine and screw into one of his welled fishing-smacks. Scarcely a lobster, out of twenty thousand put alive into the boat, was lost, whilst large numbers of those brought in sailing smacks perish. Salmon, cod, and other fish, are brought alive with the same success in the welled steamers from the North Sea and the coast of Scotland. It is almost time that some new ground were found in place of the famous Dogger Bank, which has now been preyed upon by so many nations for centuries, and has supplied so many generations of Catholics and Protestants with fast and feast food. No better proof that its stores are failing could be given than the fact that, although the ground, counting the Long Bank and the north-west flat in its vicinity, covers 11,800 square miles, and that in fine weather it is fished by the London companies with from fifteen to twenty dozen of long lines, extending to ten or twelve miles, and containing from 9,000 to 12,000 hooks, it is yet not at all common to secure even as many as four score fish of a night--a poverty which can be better appreciated when we learn that 600 fish for 800 hooks is the catch for deep-sea fishing about Kinsale.
