Part III. — JSinth Annual Report 
The Board propose t.) transport clams from tiie Firth of Forth to 
selected localities ia tiie Moray Firth, when? beam-trawli/ig is 
prohibited, with the view of developing cliim-beds for the use of 
the fishermen alon^jj the neighbouring coast?. 
7. PHYSICAL OBSERVATIONS. 
In the present Keport will be foiuid an elaborate paper by 
Dr H. E. Mill, F.K.S.E., F.R.S.G.S., on the physical observations 
made at the tixed stations on the East and VVe:it Coasts, and 
on board the ' Garland.' The records of the temperature and 
density of the sea thus obtained constitute the most extensive 
yet collected in this ©ountry, and have given S( me very interesting 
results. The observations on th.e transparenc}' . i the water in the 
Firth of Forth are unique. Dr Mill discusses in detail the sea 
temperature, specific gravity, and salinity, at the various stations, 
and saggists several methods by which the relations of fish-life to 
physical conditions may be traced. The most important of his 
conclusions are as follows : — 
The temperature uf the water on the East Coast is lower at all 
times of the year than that on the West Coast. On the E ist Coast 
the fresh waters of the Forth and Tay are carried by the tide north 
and south along the shores, and do not spread far out to sea The 
effect of the tide is even more important thjn that of sun-heat in 
changing the temperature of the water through the day. 
8. SCHEME OF SCIENTIFIC INVESTIGATIONS 
FOE 1891-92. 
The following, amongst other investigations and scientific work, 
will be carried on during the current year. 
1. Sea Fisheries. 
A. Special Inquiries. 
1. Inquiries into the influence of beam-trawling and other 
modes of fishing. 
2. ICxperiraents as to the introduction of the Common or English 
Sole into the protected waters of St Andrews Bay and the Firth 
of Forth.
