110 FISHING IN THE NEIGHBOURHOOD OF PLYMOUTH. 
order for practice either from a fort or a gunboat was given, some 
signal or official notice was displayed in the fishing quarter of the 
adjoining port or fishing village or villages. 
It seems certain that if some notification of this kind were given, 
fewer fishing boats would be found to interrupt operations by appear- 
ing in the line of fire. 
With reference to the collection of particulars as to the positions 
of the boats, the method adopted has been first of all to form a 
committee of fishermen representing the various branches of the 
industry, viz. trawlers, drift-net men, &c., and to obtain regular 
information from them as to where they themselves and the majority 
of their neighbours were working. Latterly, the collection of this 
information has been augmented by the efforts of Roach, the fisher- 
man of the Association. 
The great advantages to be derived from telegraphic communica- 
tion with isolated lighthouses and lightships, so ably advocated by a 
prominent member of the Marine Biological Association, comes most 
forcibly into view in this connection. Not only could the indica- 
tions of the movements of shoals of fish be communicated to the 
fishermen, but the positions of the fishing boats at work on the 
grounds within a radius of many miles could most readily be ascer- 
tained, and communicated to officers of either service controlling 
gunnery practice in the locality. 
The key to the symbols used in the charts is again repeated. . In 
the last numbers the symbol used to represent long-lining was 
omitted by mistake. Comparatively few boats are now engaged in 
this industry at Plymouth. The symbol will be found below.
