and gravel).

_c_, inner wall, is 0.28 m.--11 in.--wide.

The width of the inner wall being the average thickness of all the other
walls in the whole house, the suggestion is not improbable that it was
built first, and the outer one, which is made of larger stones, added
subsequently for additional strength, and the interstice filled up as
the work rose.

The line _a A_ is 17.28 m.--56 ft.--long. From _A_ it runs down to the
south for 8.10 m.--27 ft.--, thence east, 17.28 m.--56 ft.--, to connect
with the north-east corner of the eastern wing. It thus forms an aisle,
and at the same time closes the court to the north. A rectangle of 8.10
m. x 17.28--27 ft. x 56 ft.--consists of 4 longitudinal sections of 3
rooms each, which, while their length is uniformly 2.70 m.--9 ft.--(from
N. to S.), have widths from W. to E. of 5.46 m., 3.18 m., and 3.62
m.--18 ft., 10 ft., and 12 ft. All the rooms are on the same level, and
they are the largest and best preserved of any in the entire area of
ruins. Room _I_ has even an unimpaired roof.

The north wall of _a A_ stands out boldly on the highest crest of the
_mesilla_. Below it northwards, a small hill of stones, from which
timbers occasionally protrude, forms a tumbled and confused slope of
inextricable ruin; and beyond this slope there extend the foundations of
walls on the level _mesilla_ up to 10 m.--33 ft.--from the northern
transverse part of the general circumvallation, which there is 45
m.--148 ft.--from _a A_, and 30 m.--100 ft.--long from W. to E. It thus
appears that the building _A_ had its northern annex as well as the
house _B_. To this annex I shall hereafter return.

West of line _A n_ there runs alongside of it the interesting gateway
_G_, 2 m.--6 ft. 6 in.--wide, its bottom somewhat higher than the floor
of the adjoining rooms,[118] and forming, as before stated, the
north-westerly entrance to the great inner court. It is perfectly
straight on the east as far as _r_; but then a heavy bank of stones and
gravel starts out like a lower continuation of the wall _a A_, and winds
down, curving, till close to the western circumvallation on the edge of
the _mesilla_. It thus forms a northern embankment to the gateway.
Almost parallel to it, on the opposite side of _n r_, the conical
mound or tower H constitutes the western and southern wall of the
passage _G_. This passage is therefore nearly semicircular. It is level
from _n_ to _r_, and thence descends stee
