At the same time I have, based on the same statistics, 

 attempted to obtain a general view of the progress in the most 

 important salmon district of our country viz: the Trondhjem 

 district. With this object in view I have summed the annual 

 returns of the statistics for 1880—1898 for all salmon rivers, 

 which run into the sea in the shrievalties (fogderi) Fosen, Strinden 

 and Selbu, Stjør- and Værdalen, besides Inderöen.

Curve representing the number of bagnets in the years 1880—1898 



(in thousands). 



Also I have summed the annual returns for the yield from 

 the salmon fisheries in the sea in the above-mentioned shrivalties. 

 Also I have summed the annual numbers of bagnets in these 

 shrievalties. 



The graphical tables constructed from this material are re- 

 represented in Figs. 5, 6 and 7.
