From this tabie it appears that in March and April 
the larger catches are associated with south-westerly 
winds, and in May, 1908, we again see a much larger 
catch with S.W. winds and a smaller with easterly. 
Other instances may be noticed. On the whole, it seems 
that easterly winds blowing off shore are associated with 
smaller plankton catches inside the bay. 
On looking into the weather and plankton records 
for individual days we find some cases that support this 
view, along with others that appear opposed to it. This 
is only to be expected, as even if prevalent winds have an 
important influence, the other factors in the case will. no 
doubt affect the results markedly on occasions. 
During part of one week at the end of the year (1905) 
the following gatherings were taken across Port HKrin 
naive: — 
Wed., Dec. 30th, H.8.E. to §., fresh ; Coarse net 3-2 and fine netO-8=4  c.c. 
Tri., Jan. lst, 8. W. to W.S.W., light ; Coarse net 2-4 and fine net 0-6=3  c.c. 
Sat., Jan. 2nd, W.S.W., light ; Coarse net 1-7 and fine net 0:6 =2°3 c.c, 
These show a gradual fall in the amount of the catch, 
and during that time the wind was working round from 
Hast of South to nearly West. 
At the beginning of the following week the catch 
was:—Monday, January 4th, coarse net 40 and fine net 
10=—5c.c., a considerable rise, with the wind W.S.W. to 
S.S.W., light. On these occasions any effect due to wind 
may possibly have been masked by other factors; and in 
any case the quantities dealt with are small. We would 
not attach much importance to either correspondence or 
diversity in the case of small quantities or of individual 
catches
