Half a mile further up the Bran is Ossian's Cave, part of which has been artificially made; and about a mile higher is the Rumbling Bridge, thrown across a chasm of granite about 15 feet wide. The river for several hundred feet above the arch is crowded with massive fragments of rock, over which it foams and roars; and, approaching the bridge, precipitates itself with great fury through the chasm, making a fall of nearly 50 feet. Returning to Ossian's Hall, the tourist may continue his excursion along the face of Craig Vinean, the summit of which commands one of the finest prospects in this vicinity. Hence he may form some idea of the extent to which the Duke of Atholl has carried his system of planting. His Grace is said to have planted more than thirty millions of trees in the neighbourhood of Dunkeld. _Loch Katrine._ We need scarcely remind the tourist, that the scene of Sir Walter Scott's "Lady of the Lake" is laid in this spot. The following description is from the pen of Dr. Graham, the minister of the parish:--"When you enter the Trosachs there is such an assemblage of wildness and of rude grandeur, as fills the mind with the most sublime conceptions. It seems as if a whole mountain had been torn in pieces, and frittered down by a convulsion of the earth, and the huge fragments of rocks, woods, and hills scattered in confusion at the east end, and on the sides of Loch Katrine. The access to the lake is through a narrow pass of half a mile in length. The rocks are of stupendous height, and seem ready to close above the traveller's head, and to fall down and bury him in the ruins. A huge column of these rocks was, some years ago, torn with lightning, and lies in very large blocks near the road. Where there is any soil, their sides are covered with aged weeping birches, which hang down their venerable locks in waving ringlets, as if to cover the nakedness of the rocks."
