It remains to notice some physical peculiarities of this loch. Although situated at an elevation of several hundred feet above sea-level, its temperature is so equal that the water is never known to freeze, and even the stream that flows from it never shows ice on its surface till it has run several miles into bleaker regions. The depth of the water is at some places six hundred feet, and as it lies in the immediate region of earthquake in Scotland, it is allowable to conjecture that some hidden fire of nature far below keeps the water just a point or two above ordinary heat, and thus produces the phenomenon stated. There are trout in the loch, and leave to fish can readily be obtained at either end, as the hotel keepers have boats upon the loch. LOCH TAY. Many of the lochs of which we have spoken have the advantage of Loch Tay as regards the number of their visitors, and their repute in distant parts. But in no case is greater beauty to be seen than here, and no spot in Scotland will more fully repay the labour of travelling to see it. It lies surrounded with splendid hills, Ben Lawers on the north proudly towering over the scene. It is very finely wooded over all its banks, and its slightly irregular form creates change and variety at every mile of the way. It is the merit of Loch Tay that now the visitor has 'three courses' before him, like a great statesman of our day. When he leaves Killin station at the upper end, or Aberfeldy station at the lower end, he may follow the coach route on the north side, or he may prefer the less public road on the south side, or he may sail on the bosom of the water in the steamer, the _Lady of the Lake_, launched in 1882 by the Earl of Breadalbane. From Killin, the direction of our view, the north road, which is generally followed, lies to the left. Just at the head of the road--one of the roads made by General Wade--is seen the ivy-covered ruin of Finlarig Castle, situated amidst fine woods, and having near it the burial place of the Breadalbane family. The Queen, visiting Taymouth Castle in 1842, lunched at Auchmore, where the south road strikes off. She speaks of the scene as enchanting, and it would be difficult to find a more appropriate word. Ben Lawers, the ascent of which is made from Lawers inn, has not many superiors in height in Scotland, and its ascent is not difficult, while the view from it is superb. Behind Ben Lawers, and further on running to a junction with the valley in which Loch Tay lies, is the grand district of Glen Lyon, of which many think, that from its upper reaches in the Forest of Mamlorn to where the Lyon falls into the Tay, there is not a glen in Scotland so weird and yet so verdantly beautiful. The ascent of Ben Lawers, it may be mentioned, has special charms for the botanist, boasting amidst many rare plants the drooping saxifrage (_S. cernua_,) not elsewhere found in this country. The district abounds in water and in waterfalls, including
