The figures given above refer to all the stations combined and to all 

 the collections in each year and in the two periods, but it is necessary to 

 consider the results at each of the stations, and also the results in the 

 different months in which collections were made. The total number of 

 the year's brood of plaice and the average number taken in each hour's 

 fishing in the two periods were as follow : — 



The figures show that the average number of plaice per hour at each 

 of the five stations was less in the second period than in the first, that is 

 when the collective results in all the months are considered together. 



The months in which the collections dealt with in the tables 

 were made were June, July, August, and September, but for various 

 reasons the amount of fishing in these mouths in the two periods was not 

 always equal. In June only one series of collections were obtained in the 

 first period, whereas in the second period five collections were made ; a 

 circumstance which very much reduces the value of the comparison for 

 that month. The detailed averages are given in Table III., and the 

 means are as follow : —
