XXV, XXX, that is to say of the line of the Witch Ground and Gut, and in part of 



the adjacent areas on either side. In the two cases illustrated (and more or less in the 



other associated areas) the Large Had- 

 dock were especially plentiful in 1901 

 and 1902; but the three subsequent 

 years show no further progressive 

 diminution. 



In the Shetland area (X) we have 

 a striking contrast in regard to season 

 with the last named areas, for it is 

 plain that here the maximum abundance 

 of Large Haddock occurs in summer- 

 time, and chiefly about the month of 

 July (fig. 3 5). The curve also, however, 

 indicates the existence of a small wave 

 of increase in mid-winter. From Shet- 

 land to the Scottish mainland (areas 

 Xin, fig. 37, XIV, XVII) we have as 

 a general rule a maximum in early 

 autumn, about August, September and 

 October. A winter maximum reappears 

 in the north-western areas (C, D), 



which at the same time have some share in the autumn maximum of the adjacent 



regions (fig. 36).
