During the autumn the hatching apparatus has been 
thoroughly overhauled, and is now ready for use again. 
A fresh stock of flounders (amounting to over 225 large 
healthy fish) has been collected during the last three 
months of 1900, so that part of the supply of eggs for 
the season 1901 is practically secured. With the help of 
the new steamer, and favourable weather, it is probable 
that there will be a larger number of fry set free this 
year than has yet been possible. 
Description of an Apparatus for keeping Eggs wi motion. 
(See Plate A.) 
To successfully incubate large numbers of floating eggs 
in the limited areas of the usual hatching tanks the water 
must be kept in constant movement. When the eggs 
are not disturbed they gravitate towards each other, 
forming a layer on the surface of the water. Conse- 
quently the result is a high mortality, chiefly due to 
suffocation. It becomes necessary, therefore, to employ 
some means to break up these masses. This is usually 
done by slowly raising a weighted rod placed along the
