burning with the brambles, which abound in the Desert, is
sufficient; while the bitumen, to deprive it of-its brittleness and
render it capable_of being applied to the brick, must be boiled
with a certain' proportion of oil; and after all, the tenacity of
the bitumen bears no comparison with that of the mor-_ tar.. The
bricks which N iebuhr mentions as being 'so easily separated, were
all laid in bitumen; and-I invariably found that when this was the
