Several alternatives are here possible. These three fish may have 

 been amongst the nine seen but not identified in October 1905, in which 

 case, if they had been so, a return in three consecutive seasons would 

 have been established. Also they might conceivably have been others 

 of those marked returned in season 1905 without having been observed, 

 which would have equally meant a return in three consecutive years. 

 If, however, they were not any of the nine fish observed, or were not 

 others which had returned unobserved, then a return in alternate 

 seasons is the only inference. 



Again, five other fish were marked in the Arn Burn, near Luss, in 

 November 1906, of which one was recaptured in the following year, 

 thus : — 



Date. Weight. Length. 



928 B. Marked, Arn Burn Nov. 1906 li lb. 17 in. 



Recaptured, Arn Burn ... Nov. 1907 2 lb. 22 in. 



This instance proves a return in two consecutive years. 



Further marking was accomplished in the spawning season of 1913 

 when, amongst others elsewhere, 10 fish were marked in the Finlas 

 Water. Of these, two reappeared in season 1914, as follows: — 



8349 B. Marked, Finlas 



Recaptured, Clyde nets... 



8352 B. Marked, Finlas 



Recaptured, Finlas 



These instances, the second conclusively, prove a return in two
