sections of the Economic Appendix, will be found the most 
readable and instructive parts. It is only fair to state 
that the eleven beautiful plates that illustrate the Structure 
and Life-history of the Plaice have been presented to us, 
as the cost of their production has been defrayed by funds 
from an outside source. 
Mr. Scott’s account of the Sea-fish Hatching work at 
Piel will be found on p.14. During the past year the 
work has been done upon the Flounder, and over 13 
millions of young have been hatched and distributed in 
suitable waters. Next year we hope to deal largely with 
the Plaice, and a supply of spawners, obtained by our 
steamer through the courtesy of the Fishery Board for 
Scotland from Luce Bay, has already been laid in. 
I desire to emphasise what I have pointed out before, that 
sea-fish hatcheries ought not to be regarded as merely for 
the purpose of hatching young fish and then setting them 
free in the sea. The Hatching and Kearing of fish is the 
end to have in view, and scientific men who have charge of 
Fish Hatcheries will not be content till they have succeeded 
in rearing into young fish, at a reasonable cost, a 
sufficiently large proportion of the fry which they can now 
hatch from the eggs by the million. Professor G. O. Sars 
first showed how the eggs of an edible fish (the Cod) could 
be hatched in small numbers as a laboratory experiment. 
Capt. Dannevig in Norway and the U.S. Fish Commission 
in America have devised the apparatus and technique by 
which it has become possible, with very slight mortality, to 
hatch out such eggs on an industrial scale by hundreds 
of millions. The next advance must be inrearing. It may 
be very useful to turn out large numbers of fry, but it is 
not sufficient as an ultimate aim; what we want to do 
ultimately is to hatch and rear fish. We must experiment
