In August we catch very few females. Females are in berry 

 from 2 to 44- inches. Females 4^ inches are seldom seen. 

 The majority of fish we catch are between 3^ and 5 inches, 

 and from 5 to 7 inches 15 per cent. Males and females are 

 about the same in quantity. If we start fishing in March at 

 Green Point we catch mostly males ; later on, males and females. 

 The smallest Crawfish we have seen is i^ inches. The smaller 

 we ne\'er see ; they run away and stay in their nests. There 

 has been no diminution in the supply, but more boats are now 

 engaged — 10 more than last year. We used to catch a good 

 deal of fish behind the Breakwater. We have not tried fishing 

 there for a long time. At Robben Island we fish in about 10 

 fathoms of water. In the middle of Table Bay we get none. 

 We do not know where the males go when females are so 

 abundant, perhaps to Melk Bosch. About five per cent, only 

 of the fish caught about February 15th are soft.
