Traversing the lower part of Stirlingshire, they crossed Graham's Dike;** and pursuing their course westward, left Stirling Castle far to the right. They ascended the Ochil Hills, and proceeding along the wooded heights which overhang the banks of Teith, forded that river, and entered at once into the broad valley which opened to them a distant view of Ben Lomond and Ben Ledi. **The great wall of Severus, which runs between Abercorn and Kirkpatrick, being attacked by the Scotts at the time the Romans abandoned Britain, a huge breach was made in it by Graham (or Greame), the uncle of the young king of Scots. By this achievement he conquered the whole of the country as far as the Cheviots, and the wall of Severus has since been called Graham's Dike-(1809.) "There," exclaimed Ker, extending his hand toward the cloud-capped Ledi, "beneath the shadow of that mountain, we shall find the light of Scotland, our dear master in arms!" At this intimation, the wearied Murrays--like seamen long harassed on a tempestuous ocean at sight of a port--uttered a shout of joy; and hastening forward with renovated strength, met a foaming river in their path. Despising all obstacles, they rushed in, and, buffeting the waves, soon found a firm footing on the opposite shore. The sun shone cheerily above their heads, illuminating the umbrageous sides of the mountains with a dewy splendor, while Ben Ledi, the standard of their hope, seemed to wave them on, as the white clouds streamed from its summit, or, rolling down its dark sides, floated in strange visionary shapes over the lakes beneath. When the little troop halted on the shore of Loch Venachoir, the mists which had lingered on the brow of Ledi slowly descended into the valley; and covering the mouth of the pass that led from the loch, seemed to shut them at once between the mountain and that world of waters. Ker, who had never been in these tracks before, wondered at their sublimity, and became alarmed lest they should lose their way amid such infinite windings. But Murray, who remembered having once explored them with his father, led promptly forward by a steep, rough road in the side of the mountain. As they clung by the slippery rocks which overhung the lake, its mists dissolved into a heavy shower, and, by degrees clearing away, discovered the shining heads of Ben Lomond and Ben Chochan.
