SEA-FISHERIES LABORATORY. 93 
Professor Herdman took a second series of special hauls 
in August and September. He commenced work on August 
9th, and added 52 to the official set. He also took 6 hauls 
two and three miles outside the bay. The area was therefore 
well investigated. The pelagic eggs were apparently confined 
to the bay as only a single rockling egg was captured by the 
6 hauls taken outside. The combined coarse and fine horizontal 
surface hauls in the bay averaged 2°5 egos each. The coarse 
nets captured 3°3 eggs each, and the fine nets 1°6 eggs.

Professor Herdman’s series of special hauls came to an end 
on September 26th. He was able to add 50 collections to the 
official set taken in the bay. No hauls were taken outside the 
area. The pelagic eggs have become very scarce, and were 
only represented in six coarse net collections and two fine 
net collections. One coarse net collection contained three 
rockling eggs. Two fine net collections contained two eggs 
each. The average for the whole horizontal surface col- 
lections is 0°18 eggs. The coarse nets averaged 0°24 eggs, and 
the fine nets 0°12 eggs respectively.
