trout also ascend from the lake, during floods. Be- 

 sides Loch Lomond, there are several small lochs 

 situated in the county of Dumbarton, the largest 

 of which is Loch Sloy, near Arrochar. These or most 

 of them contain trout. 



The principal streams discharging themselves into 

 the Clyde, in Renfrewshire, are the Carts, Black and 

 White. The former has its sources in Castle Semple 

 Loch, and receives, as its largest tributary, the Gryffe 

 river, which is increased higher up by the Locher and 

 other streams. The Black Cart contains fine pike, 

 perch, and braize, but its trout are on the decrease. 

 Salmon also ascend it, but not in great numbers. 



The White CART rises in the moors of Eaglesham. 

 It is supplied in its course by the Kevock-burn, the 

 Earn- water, Auldhouse-burn, and Levern-water. Near 

 its sources are a number of small lakes, Lochs Goin, 

 Brother-loch, Binnend, Black-loch, Long-loch, Knock, 

 &c. Most of these contain excellent trout, and several 

 of them charr. The charr (salmo salvelinus), I may 

 here mention, are affirmed, in the Statistical Account 

 of Scotland, to have been introduced from the lakes of 

 Mearns and Eaglesham into the Avon, a tributary of 

 the Clyde, near Hamilton, and still to exist there, 

 under the name of the Duchess Anne trout. They are 

 said to attain the length of twelve inches. In Castle 

 Semple Loch are found pike and perch, also in Loch 

 Libo and Hairlaw reservoir. 



The value of the salmon-fishings in Renfrewshire is 

 considerable. Those on the Frith belong exclusively 

 to the burgh of Renfrew, and the average amount of 

 rent drawn from them annually, betwixt the years 

 1814 and 1834, was no less than four thousand, one 

 hundred, and ninety-nine pounds, one shilling ; about
