fonneel in essentials to that of N-I, which \Ve were able to study to be 3~
acl vantage. 'Ihis was a rec tangular chamber measuring about 2.15 along
lhe front, and 1.50 m back to the rear waU against which it was built.
It had a rear wall of its OWI1, however, and this, together with relative\'
thicle side walls (considering its probably low height) reduced the infe
rior measllrments to about 1.15 m by 90 m at floor le ve l. By analogy
with th e fire-chamber of P-7, it is fairly certain that the top of this
chamber was not much more than 1.00 m abo ve the Central Chamber
Roor. :We believe it hael a slab ancl masonry top 01' "roof".
Its single opening (unless there were flues 01' ventilators in its roo n
is a miniature doorway in tre cente r of the front wall. - that is, at the
end of the sunken passage. It is of the same wiclth as the sunken passage
and the doonvay of the Central chamber (. 70 m) ancl almost as high
(.83111). Aman migbt have crawlecl through it, but he ",vould have found
ver)' little room inside. A sill at the end of the sunken passage forms the
base of this doorway. The j ambs are monolithic - la rge stones set Oll
end ; and th e lintel is a heavy stone one.
The rear wall of this affair, visible of course onl)' on the inside, was
remarkable, being composecl of potshel'ds, for the most part thick and
];¡rgc, laid horizontally in mortar. At the face, the rings we['l~ laiel in the
face or toward the interior in such a wa)' as to maintain an appl'oximate
horizontal position for the sherds and at the same time to leave a minimum
of pI aster exposedin the face. This wall, about .30 111 thick at the base,
leaneel out as it rose. Badly fallen, the quantity of fall en sherds, abour
2000, indica teel that probably it originally rose to the under side of the
top or roof of the chamber. The sicle walls, and the short portions of
the jamb stones exposed on the reJ r 01' inside, were not thus protected.
Neither charcoal nor surely identifiable ash were found in the debris
of this constrllction. It was probably swept out frequen tly. The
evidence of long-continued or hot fires was however, very clear. This
consisted in the cracking and calcining of si de walls, jamb stones and
lintel, always in the place s to be expected, never elsewhere.
The mortar of the side walls had be en so badly disintegrated thar
they were traced with difficulty, inside and out. O n the inside, man)'
stones were so cracked into fragments as to be unrecognizable as such
However, several large blocks remained in position, though cracked into
many pieces. Exposed 'surfaces were so soft as to lead us at first to
suppose they were disintegrating stucco. Fractured surfaces ,vere often
of a bluish hue, and the hagments were angular.
One of the jamb stones was split longitudinally in two. Both were
badly scaled and soft 011 the exposed parts of the rear surfaces, hard
where they abutted the ends of the side wall s. The surfaces forming
the sides of the door\\,;)v \Yu-e soft a t the inner corners, becoming
