182 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 (Sa/mo salar) in Australasian waters 
have ended in uniform failure ; but the common British brook 
trout (Sa/mo 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 Fie/d newspaper for July 26th, 1902, 
and extract therefrom the following as an instance in point :— 
“Sport 1n New ZeaLtanp.—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 
fish, the largest about 3 1b. About a month later my two boys

over four hundred fish, which averaged about a pound or a 
little over ; I only obtained one fish over 6 lb., but they are 
very game, and give lots of sport. After fishing several of 
the northern rivers without any blank days, I tried some of the 
southern ones, and had capital sport, as my note-book shows : 
Owaka River, fourteen fish, 22 lb., for a half-day ; following 
day, seven fish, 16 lb., one a nice one of 5 lb. Makarewa 
River, eleven fish, 18 lb.; six fish, 11 lb. ; nine fish, 17 lb. 
Waikiwi River, two fish, one 7 lb., one 2 lb. 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
