THE ANTONINE WALL REPORT.

burn is near the east side of it. The vallum here, as usual
in Seabegs Wood, is high and prominent. At the section,
its grassy surface is 3 feet above the stone bottoming.
The kerbs, the outer faces of which are 14 feet 3 inches
apart, are of squared freestone, with intermediate rough
bottoming in which yellowish white freestone predominates.
When the cutting was first made, some large stones resting
above the bottoming suggested further inquiry; for they gave
the prima facie impression that the bottoming here might have
had two rows or courses of stone, instead of the normal sino-le
row as found invariably at Croy and Barr Hill. An extension
of the section gave the real explanation, viz., that there was a
culvert here. This culvert is of the same design as the one
found at Barr Hill No. 2; with this distinction, however, that
while the latter, following the lie of the ground, is inclined to the
south, this one, similarly following the level on which the vallum
stands, is inclined to the north. The top stones forming the lid
or cover of the culvert are not flat on their upper surface. The
kerb on the south is almost 10 inches higher than the one on the
north. On the south side, accordingly, the mouth or entry of
the drain is indicated by two stones set to a V angle with a large
stone laid over them, which latter appears to have been split in
two to make it fit for the purpose. The covering of the culvert
is formed of large stones, some of them relatively high and
pointed. Some are of amygdaloidal trap, similar to the rock of
the neighbouring hills. At the northern mouth or exit of the
drain, the bottom is formed by a large flat stone, which thus
appears to have served as spout at the outlet. The soil is a light
sandy earth, with more small stones in it than were found in
former cuttings. There are a few signs, but these very doubtful,
of the presence of some of the whitish clayey substance. The
layering through the vallum is distinctly present, but differs
somewhat in character from what it is elsewhere. Here the
dark lines are exceedingly faint; elsewhere, it is the dark lines
which mark off and draw attention to the layers. That process
is here reversed, for slight varying shades of tint in the layers
attract notice to their lines of demarcation. At some points,
these lines are of a reddish brown colour; at other points, they
