wedge-shaped tomb. The roof slabs
are two or more in number.]

In Munster the corridor-tomb takes a peculiar form (Fig. 7). It lies
roughly east and west, and its two long sides are placed at a slight
angle to one another in such a way that the west end is broader than the
east. In a good example of this at Keamcorravooly, County Cork, there
are two large capstones and the walls consist of double rows of slabs,
the outer being still beneath the cover-slabs. On the upper surface of
the covers are several small cup-shaped hollows, some of which at least
have been produced artificially.

These wedge-shaped structures are of remarkable interest, for exactly
the same broadening of the west end is found in Scandinavia, in the
_Huenenbetter_ of Holland, in the corridor-tombs of Portugal, and in the
dolmens of the Deccan in India.

In some Irish tombs the corridor leads to a well-defined chamber. In a
curious tomb at Carrickard, Sligo, the chamber was rectangular and lay
across the end of the corridor in such a way as to form a T. The whole
seems to have been covered with an oval mound. In another at Highwood in
the same county a long corridor joins two small circular chambers, the
total length being 44 feet. The corridor was once divided into four
sections by cross-slabs. The cairn which covered this tomb was
triangular in form.

In the county of Meath, in the parish of Lough Crew, is a remarkable
series of stone cairns extending for three miles along the
Slieve-na-Callighe Hills. These cairns conceal chamber-tombs. The cairns
themselves are roughly circular, and the largest have a circle of
upright blocks round the base. The chambers are built of upright slabs
and are roofed by corbelling. Cairn H covered a corridor leading to a
chamber and opening off on each side into a side-chamber, the whole
group thus being cruciform. In these chambers were found human remains
and objects of flint, bone, earthenware, amber, glass, bronze, and iron.
Cairn L had a central corridor from which opened off seven chambers in a
very irregular fashion. Cairn T consisted of a corridor leading to a
fine octagonal chamber with small chambers off it on three sides.

The chief interest of these tombs lies in the remarkable designs
engraved on some of the stones of the passages and chambers. They are
fairly deeply cut with a rather sharp implement, probably a metal
chisel. They are arranged in the most arbitrary way on the stones a
