from Germany. 
Though in this country there are perhaps some of the 
finest fish hatcheries in the world, less attention is paid to 
the cultivation and maintenance of ponds and streams than 
to restocking them, when depleted ; and besides the Salmon 
fishery, there is only the Eel fishery, which is carried on for 
purely commercial ends. This, of course, was not always so, 
as the remains of Fish stews to be found near every Abbey 
and Manor House testify. 
Switzerland, Germany, France, and the United States have 
contributed most largely to the Science of Limnology, while 
Hungary, Denmark, and other countries are also doing work 
in this direction. 
The scientific study of the subject was neglected in this 
country (with the exception of a paper by H. R. Mill, on the 
Bathymetrical Survey of the English Lakes) until in 1900 
Sir John Murray and Mr. F. P. Pullar undertook a general 
survey of all the Lakes/ and a beginning was made towards 
a Bathymetrical Survey of the Scotch Lochs. 
In the year 1902 the Sutton Broad Biological Laboratory 
came into existence, and as this, as far as I know, is the only 
Limnobiological Station in Great Britain, and concerns 
itself more especially with the investigation of the Norfolk 
waters, I think it may be of interest to put before you some 
account of the subject, and to try to point out some of the 
special features presented by the Broads. 
The term Limnology includes the complete study of lakes 
from the Geographical, Geological, Physical, Chemical, and 
Biological standpoints ; but it is more especially from the 
biological point of view that I wish to consider the subject, 
and this branch we may designate by the word Limno-biology. 
The word Lake may be taken to apply to any body of 
water which is surrounded by land and not in daily
