Report of the Experimental Committee. 171 



had been for some weeks in the artificially saline pond contigu- 

 ous to that in which it had previously been confined. Mr Stir- 

 ling's very interesting report is annexed, together with the 

 minute measurements and description of the fish, and a lithograph 

 copy of the drawing thereof contributed by him. (Plate VI). 

 The conclusion at which Mr Stirling arrives— viz., that the fish is 

 " migratory" — corroborates the view entertained by the Commit- 

 tee, and will, it is to be hoped, remove all doubt which may have 

 existed of the fact that the Orange Fin is of the Salmon kind, 

 and the previous stage of the Whitling or Bull Trout. 



It may safely be said to be established that the Orange Fin is 

 the Smolt of the Whitling and Bull Trout, and the Black Tail is 

 the intermediate stage ; but it is not proved whether the Whit- 

 ling and Bull Trout are identical or distinct branches of the 

 Salmon tribe. 



So likewise the Smolt proper is undoubtedly the younger stage 

 of Grilse and Salmon; but no satisfactory evidence has been ob- 

 tained proving that the Grilse is a younger stage of Salmon, or 

 the reverse.
