THE SCALES OF THE SALMON ID^E 277 



before, and, if they had not been captured, would have 

 spawned for the second time. 



But the difference is still more remarkable when we come 

 to compare the relative proportion of the fish which are 

 said to have spawned three or more times. 



Mr. Menzies finds that out of these fifty-five kelt salmon 

 caught in the Add in 1913, five had spawned three times. 



Mr. Hutton, however, can only claim one out of the 4,000 

 or more Wye salmon whose scales he has examined, as having 

 spawned three times, so that the relative proportion of fish 

 said to have spawned three times in the Add and in the 

 Wye respectively, are as 1 to 363. 



From this it must be evident that if Mr. Menzies had 

 examined the scales of 4,000 kelt fish from the Add, he 

 would, if his report can be said to represent the normal 

 yearly condition of the spawning fish in the Add, have been 

 able to report the discovery of no less than 363 fish who had 

 spawned three times at least. 



THE ADD AND THE WYE 



This shows the vast difference which exists between the 

 salmon in the Add and Wye Rivers. It is of importance 

 to remember, that while the scales examined by Mr. Menzies 

 were taken from kelts, those used as data by Mr. Hutton 

 were taken from both clean and unclean fish. 



The differences between the Rivers Wye and Add are as 

 follows : The Wye is one of the longest rivers in Great 

 Britain, and it is one of the easiest for a salmon to 'ascend 

 in order to reach its spawning beds, whereas the Add is one 

 of the shortest rivers in Great Britain, and, with the excep- 

 tion of the lower water, in which I believe salmon do not 

 spawn, it is one of the most difficult rivers to ascend. Again, 

 the Wye is a river up which salmon may run every month 

 in the year, whereas the Add is one in which the run of
