vegetation; while at the same time the streams and springs are from the
same cause for the most part brackish and unpalatable. Volcanic action
probably did not cease in the region very much, if at all, before the
historical period. Fragments of basalt in many places strew the plain;
and near the confluence of the two chief branches of the Khabour, not
only are old craters of volcanoes distinctly visible, but a cone still
rises from the centre of one, precisely like the cones in the craters of
Etna and Vesuvius, composed entirely of loose lava, scorim, and ashes,
and rising to the height of 300 feet. The name of this remarkable hill,
which is Koukab, is even thought to imply that the volcano may have been
active within the time to which the traditions of the country extend.

Sheets of water are so rare in this region that the small lake of
Khatouniyeh seems to deserve especial description. This lake is situated
near the point where the Sinjar changes its character, and from a high
rocky range subsides into low broken hills. It is of oblong shape, with
its greater axis pointing nearly due east and west, in length about four
miles, and in its greatest breadth somewhat less than three. [PLATE
XXIII., Fig. 1] The banks are low and parts marshy, more especially on
the side towards the Khabour, which is not more than ten miles distant.
In the middle of the lake is a hilly peninsula, joined to the mainland
by a narrow causeway, and beyond it a small island covered with trees.
The lake abounds with fish and waterfowl; and its water, though
brackish, is regarded as remarkably wholesome both for man and beast.

The Sinjar range, which divides Western Assyria into two plains, a
northern and a southern, is a solitary limestone ridge, rising up
