an elevation only about 32 feet less. After passing over this
point, the highest traversed by the wall in all its course, the
line of the work, much obliterated, continues westward through
arable land, going close underneath the Castlehill (proper) of
Barr Hill, the striking site of a Roman station. This station,
464 feet above sea level, occupies a commanding position with a
Barr Hill.—Section No. 1. PLATE II.
[ Vcdlum, fosse, and part of outer mound sectioned.]
Passing close beside the gamekeeper's cottage, a streamlet
runs through the vallum at a point where the watercourse
forms the bottom of a steep and narrow dell. In 70 yards
measured along the face of the slope westward from the
streamlet there is a rise of nearly 50 feet. At this point
the flat summit of the ridge is reached, and Barr Hill
section No. 1 is 10 yards further west—a tine cutting at the
edge of the wood in front of the gamekeeper's house, and 101
feet east of a stone dyke. The vallum here stands up very
prominently, and the ditch is also in admirable preservation.
The section shows that the present crown of the vallum is 5 feet
above the stone base. The kerbs, the outer faces of which are
15 feet 6 inches apart, are of squared freestone, and the bottom-
ing of stones is rough but compact. The slope of the hill,
immediately southwards of the vallum, is a fall of 2 feet
6 inches in 33 feet. The base follows the slope, the south kerb
being about 1 foot lower in level than the one on the north.
The soil is red earth with more clay in it than was prevalent
on Croy, especially near the base. There are here, however,
no traces of the whitish clayey material found at Croy, or of
the white sandy soil. The layering, although faint in colour,
is remarkably regular. No fewer than 13 thin dark lines are
visible, though not very obvious until looked for, but perfectly
distinct, continuous, and systematic in parallel. Some of them
are black, some dark red, with their outer ends almost per-
pendicular to the kerbs for 4 feet above the base. On the
south side the batter is not more than 4 inches in 3 feet.
There are only fragmentary traces of two dark lines in the
