1 82 BRITISH FRESH-WATER FISHES 



bull-trout ? fish that it requires only a moderate amount of 

 experience to enable one to distinguish from each other. 



On the other hand, the proposition of a common descent 

 has received remarkable support in recent years from what has 

 taken place in the Southern Hemisphere. Repeated attempts to 

 establish the true salmon (Salmo salar] in Australasian waters 

 have ended in uniform failure ; but the common British brook 

 trout (Salmo fario) has found a congenial home in Tasmania and 

 New Zealand, and attains a size which may well excite the envy 

 of anglers in the old country. While writing these lines, I 

 happened to take up the Field newspaper for July 26th, 1902, 

 and extract therefrom the following as an instance in point : 



" SPORT IN NEW ZEALAND. Early in the season I had 

 the pleasure of a few days' fishing with Mr. R. R. Patrick, of 

 Beith, Ayrshire, at the Kakanui River, some sixty miles north 

 of Dunedin. My biggest catch there for a day was twenty-six

 River, eleven fish, 1 8 Ib. ; six fish, 1 1 Ib. ; nine fish, 1 7 Ib. 

 Waikiwi River, two fish, one 7 Ib., one 2 Ib. These were 

 caught in about two hours' fishing just before dusk. Having 

 noticed a big one rising on the wrong side of the river for 

 me, I told a friend of mine about him. He drove out next 

 morning a distance of six miles, and was home in time for 

 breakfast at nine with two pictures of big brown trout ; they 

 weighed 7 Ib. each, and might have been brothers. My friend 

 told me he caught one just where I had described noticing the
