This agrees, essentially, with the horizontal hauls, it being only at 

 Stations 10213, 10215, 10223, 10230, 10232, and 10247, that eggs 

 were taken in any numbers in any of the nets.^ 



The results of the two classes of hauls, quantitative and horizontal, 

 for 1915, were as follows: — 



Egg catches, at stations where both types of hauls were made. 



f = 25 — 100 



m = 100 + 



This table shows that there is little correspondence between the 

 two sets of hauls; thus in two instances the Aertical net caught no eggs 

 (Stations 10284, 10287) though the horizontal hauls yielded large num- 

 bers. And on the other hand, in two instances (Stations 10304, 10306) 

 the catches of the vertical net were larger than those of the horizontal 

 (surface) nets. Hence to plot the abundance of eggs in the Gulf from 

 the quantitative hauls alone would give a very erroneous result. The 



1 In 1914 fish eggs were taken at the following Stations only:- 

 10224, 10226, 10230, 10232, 10236, 10247, 10248, 10249.
