APPENDIX II. 



A CONTRIBUTION TO THE LIFE- HISTORY OF THE 

 SALMON, AS OBSERVED BY MEANS OF MARKING 

 ADULT FISH. 



[Third Paper.] 



BY 



W. L. OALDERWOOD, 



Inspector of Salmon Fisheries for Scotland. 



In continuing the marking of salmon an attempt lias been made 

 to extend the area of operations, and, as far as possible, to gain 

 information along lines suggested by previous results. The number of 

 recaptures which I am able to report is not so great as in my second 

 paper \Ticeuty -second Annual Report, Part II., p. 84], but the results 

 are interesting because of additiomd recaptures on the coast — so that 

 I am able to present a chart of these — and because the proportion of 

 spring fish taken is considerable, especially from the livers Helmsdale 

 and Brora. The total number of recaptures since my last paper is 

 thirty-seven. The particulars are tabulated as formerly in the con- 

 secutive order of the mark-numbers.
