NATURAL HISTORY OF BRITISH SALMONIDA 151 
appears to differ from this view, as it is evident that if the fish 
do not run up the rivers till November, they spawn /a/er than 
the salmon ; whereas Yarrell asserts on the contrary that ‘ they 
ascend rivers for the purpose of spawning, in the same manner 
as the salmon, but earlier in the season; and the fry are believed 
to go down to the sea sooner than the fry of the salmon.’ 
This discrepancy is possibly to be explained by the different 
habits of fish of different waters. 
Amongst the localities in which the bull trout is known to 
exist may be mentioned some of the streams of Devonshire and 
Cornwall, the Severn, the Usk, and several of the rivers of 
South Wales (where it is called the Sewin), and according to 
Dr. Heysham, in some of the Cumberland waters debouching 
into the Solway Frith. In Ireland it occurs very generally on 
either side of the northern portion of the island ; and Killala 
Bay, Donaghadee, Florence Court, Beleek, Crawfordsburn, 
Nanny Water, Ballyhalbert, and Dundrum are all referred to 
by Thompson as places whence he had obtained specimens. 
Sir William Jardine mentions the bull trout as being found in 
the Annan, Dumfriesshire ; and Mr. Low recognised it as an 
inhabitant of the Loch of Stenness, Orkney. The Liddel, 
which runs through Roxburghshire, appears to have been once 
renowned for this fish. Sir Walter Scott, in his notes to the 
‘Lay of the Last Minstrel,’ quotes an old rhyme celebrating the 
places in Liddesdale remarkable for game : 
Billhope braes for bucks and raes, 
And Carit haugh for swine ; 
And Tarras for the good Bull Trout, 
If he be ta’en in time. 
‘The bucks and roes, as well as the old swine, are now extinct 
but the good bull trout is still famous.’ 
It has been asserted that the trout of the celebrated Coquet, 
commonly spoken of as ‘Cequet trout,’ are, in fact, the bull 
trout, but the ‘ Kelso Mail’ criticises the assertion as being wholly 
inaccurate. ‘The Coquet trout,’ says the writer of the article,
