A comparison of the tables referred to and of the curves (PI. IV.) 

 shows that in certain cases the fluctuations in the two districts are com- 

 plementary, a rise in one being associated with a fall in the other, and in 

 other instances they fluctuate together, both rising or both falling in the 

 same year. 



Thus in the period when the productiveness of the fishing in Loch 

 Fyne was least, in 1872-1874, there was a rise in the yield in the 

 Campbeltown district, and it fell again as the Loch Fyne fishing improved, 

 conditions which might be explained on the assumption that shoals which 

 usually entered Loch Fyne from Kilbrennan Sound remained in the 

 Sound in those years. The figures for the years 1871 to 1875 are as 

 follows : —

The same sort of relationship is shown in the years 1884-1890, the 

 number of crans taken in the two districts in each of those years being as 

 follows : —

But in the years 1895 and 1896, when the yield in Loch Fyne was low, 

 the yield in the Campbeltown district was also low, viz : —

In the first portion of the period of recent depression in Loch Fyne 

 (from about 1900 to last year), the catch in the Campbeltown district 

 was above the average, but iu the kst three years it fell below it, as the 

 following figures show: —

A possible explanation is that the shoals that usually visit the area did 

 not in the first part of the period of depression penetrate in large numbers
