The ruined castle shown in the view occupies a prominent position upon a heart-shaped peninsula. The visitor will find little but bare and massive walls to tell him of the extent of this fortress, once covering sixteen acres in extent, and forming the chief stronghold in the south-west of Scotland. For many years after the castle fell into ruin it is said the king's tenants used it as a quarry for building stones, and Chambers, in his _Picture of Scotland_, speaks of one honest burgher who then 'warmed his toes beside a pair of fine jambs procured in Bruce's castle.' From the appearance of the ground, it is evident the neck of the peninsula could be put under water for defensive purposes, having both an outer and an inner defence of this kind, besides one or more intermediate fosses that speak of the same use. The present is not believed to be the original castle built by the Lords of Annandale, but a subsequent erection of the thirteenth century. The days of warlike lords and border forays are over for the Castle of Lochmaben, and now it is to be regarded merely as a splendid addition to the picturesque attractions of this very charming district. Boats may be hired for a row or sail over the placid bosom of the loch, and on a fine autumn evening no more delightful pleasure could be got. Besides its other attractions, Lochmaben presents a peculiar fact in natural history, for in its waters are found--in addition to other fish--the vendace, a species of fish found in no other loch. It is popularly but erroneously called a fresh-water herring, for it belongs to the family of _coregonus_, one of the salmonidae. This rare fish takes no lure, and thus can only be netted, and the fishing for it in the Castle Loch is limited to one day in the year, in July, when the vendace club meet, fish, and dine. The Mill Loch, another and lesser of those surrounding the burgh, also contains vendace, which are fished for one day in August. The Castle Loch measures a mile long by three quarters broad, the Mill Loch is half a mile by quarter of a mile, and the other waters are the Kirk-Loch, Hightae Loch, &c. LOCH DOON. Although intimately associated with those scenes to which Burns so plaintively puts the question 'Ye banks and braes o' bonnie Doon How can ye bloom sae fresh and fair?'
