I followed the road past the Black Bull Inn, which stands on the exact site of the Wall; and then, to keep the trail, I had to turn off on the right, along a lane which led to a field-path to Sandysike farm-house. Here, in the hedge on my left, were Wall-stones once more. The farm-buildings at Sandysike are very ancient-looking and picturesque. There is a hexagonal cart-shed built of stone, with a tiled roof, and an old barn, of brick, with strikingly lofty round-headed arches; but I did not see the Roman sculptured stones of which it boasts. The track of the Wall can be followed down to the edge of the Cam Beck, the ditch being our guide; but here for the first time I deliberately abandoned it! I could not cross the Cam Beck where the Wall had crossed it without getting very wet and dirty, and part of my compact with myself was to keep clean and dry, if possible. The river cuts its way at this point very deeply through the red sandstone. Sheer red banks stand out of the water. A very high weir across the stream would have made {184} crossing easier, but a large tree-trunk had fallen over it, and blocked the way. Already grass and plants were growing out of its slippery black sides. Reluctantly I turned back, and took the path to Castlesteads, the house of Mrs. Johnson, whose garden is on the site of a Roman fort. The path brought me through woodland and shrubbery to a house which proved to be the head gardener's. The barking of a dog produced the gardener, who took me to the lawn which represents the centre of the fort. A little summer-house at the edge of the lawn serves as protection to a number of Roman altars, and other sculptures, found within the fort. They were all in the red sandstone of the neighbourhood, some covered with a bright greenish-yellow lichen. The largest altar was dedicated to Jupiter by the second cohort of the Tungrians. The site of this fort lies between the Wall and the Vallum, which latter curves to the south to avoid it. This was proved by excavations made by Professor Haverfield and Mr. and Mrs. T. H. Hodgson in 1902. They traced accurately the position of the Vallum in this section of the fortifications for a distance of about 4 miles, from Garthside to the south of Cumrenton--a work needing endless patience. On one occasion many trenches had been dug and measurements taken, but Mr. Hodgson had not time to plot it all out till the end of the season. When he did so, all the points where {185} the Vallum had been struck fell into one straight line! The walls and gateways of this fort appear to have been standing until 1791, when the ground changed hands, and the house of Castlesteads was built. Then the standing masonry was removed, and the whole site levelled.
