COMMITTEE B — DECEMBER 1903 ( 24. ) 
employed a small trawl in Denmark to enable them to fish at great depths in 
Icelandic waters, and it would be difficult for them to use a large trawl as weil, 
when fishing in the North Sea. He thought a uniform trawl was not needed. 
Prof. Max Weser thought that a standard trawl was scarcely needed 
because of the large number of other factors to be taken into consideration, e. ¢., 
the build of the ship and the man in charge of the fishing experiments. 
Dr. Reprxe ashed for a definition of the words “standard trawl”, as, theo- 
retically, he thought it excellent to have identical trawls. Mr. Garsrane had seen 
the Dutch trawl. Did he think it of a pattern sufficiently similar to render the 
results comparable with those of the “Huxley” ? 
Mr. Garstane in reply stated that a standard trawl for different boats would 
be one sufficiently identical within reasonable limits in the size of aperture and 
mesh and weight of ground rope. The necessity of adapting the weight of the 
ground rope to different soils was a difficulty, but it could be overcome by adop- 
ting a standard length and weight of iron chain which could be coiled round the 
rope as required. It could then be stated in the records of each haul whether 
this chain was being used or not, and they would thus all realise at once the 
conditions of the experiment. 
Dr. Repexe enquired whether the difference between the trawl used by 
Holland and that used by England fell within reasonable limits. 
Mr. Garsrane considered that they were practically identical in size, but new 
experiments should be made in order to settle the weights of ground rope most 
suitable for all such nets. He understood that the ground rope of the “Poseidon’s” 
trawl was much lighter than that of either the “Wodan” or the “Huxley”. 
Dr. Hemcxe did not know whether his ground rope was light or heavy, but 
he did not think it of great importance. He proposed to take more than one 
ground rope and mention in his reports the exact ground rope used on all of the 
experiments. He agreed with Dr. Prrersen that the 50 ft. trawl was good and 
answered well. They had a similar one also on the “Poseidon”. A standard 
trawl, he thought, would be too expensive for the different countries. 
Dr. Kye said that he had some experience in this direction, and he believed a 
standard trawl quite impossible at the present time. He agreed it would be quite 
possible to construct trawls having the same size of mesh, head line and ground rope: 
but such trawls would not fish the same on different boats with different men m
