is_ as they are now
scattered, extends nearly north and south 140 m.--460 ft.--and east and
west about 16 m. to 26 m.--50 ft. to 80 ft.--thus forming a rectangle of
140 m. x 20 m.--460 ft. x 65 ft. To determine the exact size of the
building I proceeded to measure each compartment for itself, judging
that the total number of these apartments, adding to their sizes the
thicknesses of the walls, would finally give, within a few decimetres,
the exact length and width of the house. On the ground plan I have
numbered this building B.[103]

Beginning at the north-west corner, I ran my line almost due east to
within 10 m.--33 ft.--of the circumvallation, where I found the
north-east corner indicated by a broken post of wood. Along this line I
met the following sections from west to east: 2.92 m.--9 ft. 6 in.; then
a gangway, 1.55 m.--5 ft.; chamber, 3.22 m.--11 ft.; gangway, 1.21 m.--4
ft.; and three chambers, 2.09 m., 2.72 m., and 2.72 m.--7 ft., 9 ft.,
and 9 ft.--respectively, thus giving, adding to it eight walls of a
uniform thickness of 0.33 m.--13 in.,--a total width of 19.07 m.--63 ft.
Its length was easily found to be 8.56 m.--28 ft.; the northern
appendix, therefore, forming a rectangle of 8.5 m. x 19 m.--28 ft. x 63
ft.,--and containing, as the ground-plan shows, ten rooms and two
corridors, the latter running through the structure from north to south.
It will also be noticed that the two middle rooms are the largest,
measuring each 4.28 m. x 3.22 m.--14 ft. x 10 ft. I must also advert,
here, to the fact that this structure is extremely ruined, and that the
east part of it exposes the surveyor to dangerous errors.

The line _a b_, and its continuation eastwardly to _c_, appears to form
the main northern wall of the whole structure. Here the annex, just
described, terminates. This wall is of unequal thickness. In the
north-westerly projection from _a_ to _b_, a length of 8 m.--26
ft.,--its thickness is 0.63 m.--2 ft.; from _b_ to _c_, on the eastern
line, it is only 0.33 m.--13 in.--thick. This inequality indicates also
a division of the structure to the southward, as far as the line _d d
d_, into two longitudinal sections. The western one, whose four corners
are respectively _a_ _b_ _d_ _d_ in the diagram, contains eighteen rooms
of equal size, measuring each 3.71 m. x 2.25 m.--12 ft. x 7 ft.; it is
consequently, inclusive of the rear wall and the sides, 24.24 m. x 8.08
m.--80 ft. x 27 ft. The eastern division, comp
