"has a feature common to all these slate
weapons--they seem to have been saturated with oil or fat, as water
does not adhere to them, but runs off as from a greasy surface."
Another highly ornamental piece of cannel coal is in the form of a
short spear-head with a thickish stem. The stem is adorned with a
series of hollows and ridges running across it; radiating lines
running from the stem to the margin. Another group of these
remarkable objects shows markings of the cup-and-ring order, circles,
linear incisions, and perforations. Some of these ornamentations are
deeply cut on the naturally rough surfaces of flat pieces of
sandstone, whilst others are on smooth stones artificially prepared
for the purpose. A small piece of flint was supposed to have been
inserted into a partially burnt handle. There are several examples of
hammer-stones of the ordinary crannog type, rubbing-stones,
whetstones, as well as a large number of water-worn stones which might
have been used as hand-missiles or sling-stones. These latter were
not native to the hill, and must have been transported from burns in
the neighbourhood. There are also two upper quern stones.

MISCELLANEOUS OBJECTS.--A number of splintered pieces of bone, without
showing any other evidence of workmanship, have linear incisions, like
those on some of the stones, which suggest some kind of cryptic
writing like ogams. There are also a few water-worn shells, like
those seen on a sandy beach, having round holes bored through them and
sharply-cut scratches on their pearly inner surface. But on the whole
the edible molluscs are but feebly represented, as only five oyster,
one cockle, three limpet, and two mussel shells were found, nearly all
of which bore marks of some kind of ornamentation. But perhaps the
most grotesque object in the whole collection is the limpet shell with
a human face sculptured on its inner surface.

"The eyes," writes Mr. Millar, "are represented by two holes, the nose
by sharply-cut lines, and the mouth by a well-drawn waved line, the
curves which we call Cupid's bow being faithfully followed. There is
nothing at all of an archaic character, however, in this example of
shell-carving. We found it in the interior of the fort; it was one of
the early finds--nothing like it has been found since; at the same
time we have no reason for assuming
