relative abundance between the catches made along different section lines, 

 are not justifiable unless the catches are made almost simultaneously. 

 Since the great distances separating the sections precluded the possibility 

 of simultaneous operations along all three sections, it is not considered 

 advisable to draw other than general conclusions as to relative abundance. 

 It is evident, however, that salmon are present in all the waters east of 

 a line from the Islands of Four Mountains to Nunivak Island, via the Pribi- 

 lofs, and it appears that salmon are more abundant in the waters on the 

 continental shelf than they are in the waters beyond the edge of the shelf. 

 It also appears that red salmon are as abundant, if not more so, around the 

 Pribilof Islands as they are south of the Islands, but that their abundance 

 decreases to the north of those is lands „ 



When taking the salmon out of the gear a record was kept, insofar as 

 was possible, of the side of the net that the fish had entered. As the
