west over a distance of 3300 yards,
but the line is broken at two points in such a way that the whole forms
three groups. The most westerly, that of Menec, consists of eleven lines
of menhirs and a cromlech, the total number of stones standing being
1169, the tallest of which is 13 feet in height. The central group, that
of Kermario, consists of 982 stones arranged in ten straight lines,
while the most easterly, that of Kerlescan, is formed by 579 menhirs, 39
of which form a rectangular enclosure.

There are other _alignements_ in Brittany, of which the most important
is that of Erdeven, comprising 1129 stones arranged in ten lines.
Outside Brittany _alignements_ are unusual, but a fine example, now
ruined, is said to have existed at Saint Pantaleon north of Autun. In
the fields around it are found large quantities of polished stone axes
with knives, scrapers, and arrow-heads of flint.

We have already noticed the cromlechs which form part of the
_alignements_ of Brittany. There are other examples in France. At
Er-Lanic are two circles touching one another, the lower of which is
covered by the sea even at low tide. Excavations carried out within the
circles brought to light rough pottery and axes of polished stone. Two
fine circles at Can de Ceyrac (Gard) have diameters of about 100 yards,
and are formed of stones about 3 feet high. Each has a short entrance
avenue which narrows as it approaches the circle, and in the centre of
each rises a trilithon of rough stones.

Of the definitely sepulchral monuments the dolmen is common in all
parts of the French megalithic area. It will suffice to mention the
magnificent example known as the Table des Marchands at Locmariaquer.
Perhaps the most typical structure in France is the corridor-tomb in
which the chamber is indistinguishable from the passage, and the whole
forms a long rectangular area. This is the _allee couverte_ in the
narrower sense. In the department of Oise occurs a special type of this
in which one of the end-slabs has a hole pierced in its centre and is
preceded by a small portico consisting of two uprights supporting a
roof-slab (Fig 10). A remarkable example in Brittany known as Les
Pierres Plates turns at a sharp angle in the middle, and is thus
elbow-shaped.
