Apart from hooks, and lines, and ordinary nets, fishermen have, from time immemorial, made use of two kinds of implements for getting at sea- creatures which live beyond tide-marksthese are the "dredge" and the "trawl."

The trawl is a sort of net for catching those fish which habitually live at the bottom of the sea, such as soles, plaice, turbot, and gurnett.

After drifting with the tide for six or seven hours the trawl is hauled up, the marketable fish are picked out, the others thrown away, and the trawl sent overboard for another operation.

But the first news from the Challenger opens up new possibilities for the trawl.

We were extremely anxious to get some idea of the general character of the Fauna, and particularly of the distribution of the higher groups; and after various suggestions for modification of the dredge, it was proposed to try the ordinary trawl.

We had a compact trawl, with a 15-feet beam, on board, and we sent it down off Cape St. Vincent at a depth of 600 fathoms.

The experiment looked hazardous, but, to our great satisfaction, the trawl came up all right and contained, with many of the larger invertebrate, several fishes....

After the first attempt we tried the trawl several times at depths of 1090, 1525, and, finally, 2125 fathoms, and always with success.

" To the coral-fishers of the Mediterranean, who seek the precious red coral, which grows firmly fixed to rocks at a depth of sixty to eighty fathoms, both the dredge and the trawl would be useless.

These "tangles" bring up immense quantities of such animals as have long arms, or spines, or prominences which readily become caught in the hemp, but they are very destructive to the fragile organisms which they imprison; and, now that the trawl can be successfully worked at the greatest depths, it may be expected to supersede them; at least, wherever the ground is soft enough to permit of trawling.

It is obvious that between the dredge, the trawl, and the tangles, there is little chance for any organism, except such as are able to burrow rapidly, to remain safely at the bottom of any part of the sea which the Challenger undertakes to explore.

"] As Dr. Wyville Thomson's recent letter, cited above, shows, the use of the trawl, at great depths, has brought to light a still greater diversity of life.

She cannot send down her dredges and her trawls into these virgin depths of the great ocean without bringing up a discovery.

When the Challenger's trawl brings up an Ichthyosaurus, along with a few living specimens of Belemnites and Turrilites, it may be admitted that she has come upon a cretaceous "outlier."

HOW SOLES ARE CAUGHT.The instrument usually employed is a trawl net, which is shaped like a pocket, of from sixty to eighty feet long, and open at the mouth from thirty-two to forty feet, and three deep.

The submarine first concentrated her fire on the Nelson, which immediately slipped her trawl and went to action stations.

Some are caught by men who push a small net over the sands near shore, but most are caught by the shrimp-trawl, a large net cast from a small sailing vessel.

They carry a large neta shrimp-trawl, it is calledwhich is drawn over the sandy home of the Shrimp.

Beneath us, to the left hand, is the quay-pool, now lying dry, in which a dozen trawlers are lopping over on their sides, their red sails drying in the sun, the tails of the trawls hauled up to the topmast heads; while the more handy of their owners are getting on board by ladders, to pack away the said red sails; for it will blow to night.

August is engaged in the trawl-fishery, when all sorts of flat fish are taken in a net called by that name.

Nelson is going to put over the 8 feet Agassiz trawl.

From this he took us amongst the tow-nets with their beautiful silk fabrics, meshes running 180 to the inch and materials costing 2 guineas the yardto the German tow-nets for quantitative measurements, the object of the latter and its doubtful accuracy, young fish trawls.
