Aberdeen Fishery Statistics. 18 
For example, let us trace by this means, in one or two instances, 
the changes throughout the year in the number of vessels which 
resort to some one particular fishing-ground. or it is part of the 
common knowledge of every fisherman that each ground has its 
particular seasons of abundance, and with great regularity the 
fleets resort to one or another at the appropriate times. In any 
single year we trace imperfectly the general regularity of these 
movements, for the movements of the fish are themselves subject 
to irregularity, and the fishermen who follow the fish do not go 
blindly according to habit and rule. But, summing together for 
a number of years the movements of the fleets, there is obtained, 
with an approach to mathematical regularity, an indication of the 
rule by which those movements are guided and governed. 
Let me illustrate this by the case of the three adjacent areas, XV., 
XIX., and XIV. (Tables VII., VIII., [X.), that is to say, the areas 
which include Bressay Shoal, the Witch ground to the southward 
thereof, and the area south of Shetland, including Fair Isle 
Bank, to the westward of the Bressay area (fig. 3).
