of further experiments in lobster culture during the summer and 

 autumn. The lobster pond was carefully cleansed, and, by 

 piling together a number of large stones and bricks at the deeper 

 end, hiding places were prepared for the lobsters. 



" By the middle of June six ' berried ' ones, with eggs in 

 advanced stages of development, had been purchased from local 

 fishermen, and on various dates up to and including Sept. 3rd 

 12 more were brought in, making a total of 18, exactly the 

 same number as were obtained last year. The eggs of the first 

 few being well advanced, they were put into the uppermost 

 compartments of the hatching tanks in anticipation of the 

 early appearance of larvae, and, in view of Mr. Gunn's results 

 last year, of continuing the use of the hatching tanks for 

 rearing purposes. 



" The old trouble — premature shedding of the eggs by the 

 parent lobsters — soon made its appearance, and, as it threatened 

 to result in considerable loss, I eventually decided to transfer 

 the lobsters to the pond. This was done, and as new ones were 

 brought in they were at once put into the pond. So far as could 

 be ascertained from careful inspection, no further egg shedding 

 occurred ; and I am now satisfied that in future ' berried ' 

 females may be kept in the pond indefinitely, without fear of a 

 recurrence of this annoying trouble. 



" The first larvae made their appearance in the pond at the 

 end of June, and by the end of the first week in July considerable 

 numbers were swimming about actively and appeared to be 

 doing well. Some of these I transferred to the hatching boxes ; 

 but the majority were left in the pond and fed daily upon 

 minced liver of crab. 



" On July 19th Mr. T. Monaghan came over from the 

 University of Liverpool to undertake the work of lobster 

 culture ; and on the 21st, when he began work, there were nine 

 ' berried ' lobsters in the pond, and several thousands of first,
