_Wednesday, August 24th._--As soon as breakfast was over, William and I walked towards the Castle, a short mile from the town. We overtook two young men, who, on our asking the road, offered to conduct us, though it might seem it was not easy to miss our way, for the rock rises singly by itself from the plain on which the town stands. The rock of Dumbarton is very grand when you are close to it, but at a little distance, under an ordinary sky, and in open day, it is not grand, but curiously wild. The castle and fortifications add little effect to the general view of the rock, especially since the building of a modern house, which is white-washed, and consequently jars, wherever it is seen, with the natural character of the place. There is a path up to the house, but it being low water we could walk round the rock, which we resolved to do. On that side next the town green grass grows to a considerable height up the rock, but wherever the river borders upon it, it is naked stone. I never saw rock in nobler masses, or more deeply stained by time and weather; nor is this to be wondered at, for it is in the very eye of sea-storms and land-storms, of mountain winds and water winds. It is of all colours, but a rusty yellow predominates. As we walked along, we could not but look up continually, and the mass above being on every side so huge, it appeared more wonderful than when we saw the whole together. We sat down on one of the large stones which lie scattered near the base of the rock, with sea-weed growing amongst them. Above our heads the rock was perpendicular for a considerable height, nay, as it seemed, to the very top, and on the brink of the precipice a few sheep, two of them rams with twisted horns, stood, as if on the look-out over the wide country. At the same time we saw a sentinel in his red coat, walking backwards and forwards between us and the sky, with his firelock over his shoulder. The sheep, I suppose owing to our being accustomed to see them in similar situations, appeared to retain their real size, while, on the contrary, the soldier seemed to be diminished by the distance till he almost looked like a puppet moved with wires for the pleasure of children, or an eight years' old drummer in his stiff, manly dress beside a company of grenadiers. I had never before, perhaps, thought of sheep and men in soldiers' dresses at the same time, and here they were brought together in a strange fantastic way. As will be easily conceived, the fearlessness and stillness of those quiet creatures, on the brow of the rock, pursuing their natural occupations, contrasted with the restless and apparently unmeaning motions of the dwarf soldier, added not a little to the general effect of this place, which is that of wild singularity, and the whole was aided by a blustering wind and a gloomy sky. Coleridge joined us, and we went up to the top of the rock.
