In pointing to 'promontory, creek, and bay,' as the characteristics of the loch, Scott has depicted its most charming attributes, while the islands, of which Ellen's Isle is the largest, help to enhance the effect. As the little steamer breaks the still waters into drops that glance like gems in the sunlight, the scene changes every moment,--changes in detail, but never in degree of beauty, for the loch is lovely throughout, and never fails to enchant the eye. The chief attraction of the loch itself is the lovely wooded isle that fills the foreground of our view, 'The wild rose, eglantine, and broom, Wasted around their rich perfume. The birch trees wept in fragrant balm, The aspens slept beneath the calm, The silver light, with quivering glance Play'd on the water's still expanse.' Seldom indeed will the casual visitor have the opportunity of viewing this scene thus, by the silvery moonlight. But in sunlight it is not less beautiful, and the description is complete. Next to the island, the point of attraction is the 'silver strand,' from whence one of the many fine views of Ben Venne may be had. While Loch Katrine thus ministers to our love for the beautiful, its waters have learned to combine the _utile_ with the _dulce_, and here, in October 1859, came Queen Victoria to turn on the water for the supply of Glasgow. Many and fierce were the controversies as to this scheme. But Lord Provost Stewart, who was mercilessly assailed for upholding such a costly scheme of water supply, is now commemorated in Glasgow by a splendid fountain in the West-End Park, and staticians and sanitary reformers are able to show that the death rate amongst the half million crowded workers in Glasgow has manifestly lessened since the city acquired the right to drink the sparkling waters of Loch Katrine. LOCH LUBNAIG. Turning aside from the formal round of the Trosachs and Loch Lomond, to penetrate into that wonderful district which the Callander and Oban railway has opened up, we reach, at no great distance from Callander, Loch Lubnaig, 'the crooked lake,' so called from its bent form, which is almost identical with the form of the boomerang. The river Leny, which drains the lake, passes through the Pass of Leny, once famous as a gateway defending the entrance to the Highlands. Here, whether viewed from the train or the road, the river is seen to rush over huge rocks, tearing, roaring, and tumbling, in a manner calculated to terrify the timid entrant to this wild district.
