as many as seven. It is
remarkable that three of the skulls showed wounds, the dead having been
apparently killed in battle. Several vases have been found and a few
pieces of bronze.

We have seen that in some of the tombs of Bou Merzoug objects of iron
were found. This makes it clear that some at least of the Algerian tombs
belong to the iron age, i.e. that they are probably later than 1000
B.C., but beyond this we cannot go. The medal of Faustina sometimes
quoted as evidence for a very late date proves nothing, as it is not
stated to have been found in a tomb. There is no evidence to show how
far back the graves go. It may be that, as MacIver and Wilkin suggest,
the parts of the cemeteries excavated chance to be the latest. At Bou
Merzoug the excavators worked chiefly among the graves on the plain and
at the bottom of the hill. The more closely crowded graves which lie on
the hill itself may well be older than these. In fact, all that may be
said of the Algerian graves is that some are of the iron age, while
others may be and probably are earlier.

In Tunis the dolmen is not uncommon, and several groups or cemeteries
have been reported. Near Ellez occurs a type of corridor-tomb in which
three dolmen-like chambers lie on either side of a central passage, and
a seventh at the end opposite to the entrance. The whole is constructed
of upright slabs of stone, and is surrounded by a circle formed in the
same way.

Morocco, too, has its dolmens, especially in the district of Kabylia,
while near Tangier there is a stone circle.

Off the north coast of Africa, and thus on the highway which leads from
Africa to Europe, lie the Italian islands of Lampedusa and Linosa. The
latter is volcanic in origin, and its surface presents no opportunity
for the building of megalithic monuments. Lampedusa, on the other hand,
consists of limestone, which lies about in great blocks on its surface.
On the slopes of the south coast there are several remains of megalithic
construction, but they are too damaged to show much of their original
form. However, on the north side of the island there are megalithic huts
in a very fair state of preservation. They are oval in form and have in
many cases a base course of orthostatic slabs.

Some miles to the north of Linosa lies the much larger volcanic island
of Pantelleria, also a possession of Italy. Here megalithic remains both
of dwellings and of tombs have been found. On the plateau of the Murs
