22 THE LIFE OF THE SALMON 



within reach of sea water. The small frv found in 

 such localities may therefore be naturally regarded 

 as in part at least the offspring of salmon which 

 have spawned in the neighbourhood. It has to be 

 recollected, however, that two parts of sea water to 

 one of fresh kills salmon eggs. It seems probable, 

 however, that other young fry, following the instinct 

 to form into shoals which we know parr possess, have 

 joined themselves to companies of larger parr, or it 

 may be have been to some extent washed down by 

 floods. In any case these small fry and all stages oi 

 parr are to be found in the upper tidal waters at all 

 seasons of the year. 



In order to ascertain whether or not smolts 

 migrated in any numbers in the autumn, and at 

 other seasons than spring, netting at Kinfauns was 

 continued through an autumn and winter. This work 

 was taken up by the Tay Fisheries Company, with 

 the permission of the Tay District Fishery Board, 

 the catches being noted and the little fish returned 

 unharmed to the water. Murie, Day, Traherne, and 

 Willis Bund have all mentioned or described an 

 autumn migration as occurring in England or Ireland, 

 but evidence on this head was wanting from Scotland. 

 In the Tay the smolts were found in a somewhat less 

 brilliant dress during the months of September and 

 November 1905, but they were in small numbers. 

 On November 7, for instance, only twenty-nine were 

 taken after fourteen hauls with a small -meshed net. 

 The particulars and a detailed description of some 

 of the specimens are given in the twenty-fourth 

 Beport of the Fishery Board for Scotland, Part II.,
