SEA-FISHERIES LABORATORY. 309 
This table shows that out in the open sea, at this date 
in April, the majority of the fish eggs were close to the 
surface, and the weighted nets towed at the same time only 
a few fathoms deeper obtained appreciably fewer (about 
29 per cent. only), except in the case of the Haddock. The 
numbers for the Cod especially show a marked difference 
- between the surface and the deeper layer. 
It may be added that this was the first day of the 
season's work from the Yacht, and all the nets were of new 
No. 20 silk used for the first time, and so presumably were 
equally effective in catching power. 
For purposes of comparison, we quote now the hauls 
made on April 17th with fine and coarse nets in Port Krin 
Bay, and with the weight net at Station III along the 
coast to the north.

Here the results seem reversed. The weight 
net has caught most eges (with the exception of 
Rockling), and in some cases more than the average 
number for a surface net on April 11th at Station I. Still, 
_the dates are not the same and the localities are not the 
same, although not far distant (five miles, and six days, 
apart) and so we do not press the contrast.
