22 THE LIFE OF THE SALMON 
within reach of sea water. The small fry 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 of 
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 
Report of the Fishery Board for Scotland, Part II.,
