CAIRN (5)

In grave No. 5 the walls on the north and the south were entirely torn
out except some stones in the bottom row of each; the upper portions
of the east and the west walls were also gone. For this reason the
rocks lying outside the structure were not removed.

The north wall, outside, was 15 feet long; the south wall, 14 feet;
the east wall, 16 feet; the west wall, 141/2 feet. The corresponding
inner measurements were, north wall, 10 feet; south wall, 10 feet;
east wall, 12 feet; west wall, 12 feet. But as the position of the
corners was uncertain these figures are no doubt somewhat in error in
either direction.

The central portion had never been disturbed, the stones lying as they
were put originally, except for a possible settling due to their
weight; the top of the rounded heap was about 4 feet high. This
justified the hope that something might be discovered beneath them.
But although the entire space within, up to the fairly defined inner
faces of the walls, was thoroughly cleaned out down into the untouched
gravelly subsoil, no trace of a bone or other indication of a burial
was found. The only artificial object was a section 31/4 inches long of
a columella perforated lengthwise, apparently lost by the wearer, as
it lay on the natural surface. This is shown in figure 19.

CAIRNS ON HELM'S FARM

To the north of the Ross farm, on the ridge which is owned by Daniel
Helm, are three stone graves made of shapeless limestone blocks such
as cover the surface around them. One of these is about 300 yards
from the bluff, on a knoll capped with the sandstone; the others are
at the break of the ridge. All have been opened, two of them
practically demolished. Those on the end of the ridge are only 14 feet
apart, measuring from their adjacent margins, and were about 16 and 20
feet in diameter as built, both being somewhat widened now owing to
the stones having been thrown outward from the central parts by
hunters. Each was probably 3 feet high.

The smaller, being least defaced and nearly free from timber, was
entirely removed, except a small portion along one margin, and the
earth beneath it examined down to the bedrock. There was no sign of a
wall; but one that would stand could not be made with stones rounded
by weathering.

Remains of at least three bodies were foun
