not such as to deflect the batter abnormally inward—that is
to say, to bend the south face of the vallum further over to
the north than elsewhere—we note that the apparent batter
of the south face of the vallum, as it rises from the south
kerb, is as follows :—
Up 2 feet, a batter or intake of 12 inches (i.e., 6 inches to
the foot), or, in other words, a slope of 2 upon 1.
Up 2 feet 6 inches, a batter of 15 inches (i.e., also 6 inches
to a foot), or a slope of 2| upon 14>
Up 3 feet 9 inches, a batter of 2 feet 4 inches (i.e., T-J-
inches to a foot), or a slope of 3f upon 2J.
Next to be dealt with is the semi-circular expansion, of which
the present limit of debris is 45 J feet south of the south kerb
of the vallum. This expansion is similar to the vallum in the
soil of its contents, with the pointed differences, that there is
scarcely a trace of any white or yellowish sand, and that there
is no whitish clayey matter. It is all of red earth with few
stones, none of them large. Throughout, it is marked with
systematic dark lines, fainter but not less certain than those
in the vallum. They cannot, however, be considered protrac-
tions of those in the vallum, since just above the south kerb
there is a decisive break of a foot or two. The lines in the
vallum stop there, and the lamination beyond that break
appears to be independent. The lines occur as follows:—
1. On the apparent original surface of the hill (1| inches
above a boulder which has had vegetation either
growing upon or imposed over it).
2. Up 2 inches.
3. Up Sh „
