32 THE SILVERY HOSTS OF THE NORTH SEA. 



assumption that there are fifty gannets in the rest 

 of Scotland for every one on Ailsa Craig, the Scotch 

 gannets alone consume 1,110,000,000 herrings. 



Estimated destruction of herring off 



the coasts of Scotland by cod, 



ling, and hake 29,400,000,000 



By gannets 1,110,000,000 



Total . 30,510,000,000 



or meat-food equivalent to over 21,000,000 bullocks 

 destroyed by only four enemies of the herring. This 

 destruction refers to only one small portion of coast 

 washed by the North Sea ; if we add to this the 

 enemies frequenting the long line of Norwegian 

 coast, with its numerous rocky islands and points 

 jutting out into the sea, such as wild fowl love to 

 inhabit, the above total sinks into insignificance. In 

 1877, according to reports furnished to the United 

 States Fishery Commission, the number of cod-fish 

 taken by Norwegian fishermen were : 



In the LofFodon Islands 29,500,000 



Other fisheries of the North 4,500,000 



At Finmark 17,500,000 



At Sondmore, Romsdal, Nordmore . . . 8,500,000 

 Estimated yield of smaller fisheries along 



the coast 7,500,000 



Total . 67,500,000 



The above total does not include the cod fisheries of 

 Germany, Denmark, and Sweden, for which estimates 

 are not at hand. Estimating upon the same basis 

 as before, that for every cod-fish taken twenty have
