inly 1 m.--3 ft. 3 in.--high,
whereas their average width may have been 0.45 m.--18 in. (Those I
measured averaged between 0.42 m. and 0.48 m.--16 in. and 19 in.) Their
appearance is shown in Pl. II., Fig. 5.

_a_ is what might be termed a door-sill, a smooth oval stone, evidently
from the drift, probably dioritic, at all events a dark-green hornblende
rock. In the present instance one was not long enough to fill the gap
left between the walls, and two were superposed. I saw no traces of
wooden lintels or sills. These doorways appeared to be generally about
0.50 m.--20 in.--above the floor, but if we deduct 0.20 m.--8 in.--for
the clay (measure having been taken from the timbers), 0.30 m.--12
in.--will remain as their approximate height over the chambers.

The few doors that I could observe are all in the longitudinal walls,
and none of them in the transverse; that is, they all open from east to
west. But not all the longitudinal partitions have doorways. It cannot,
therefore, be admitted that every transverse row was occupied by one
family, still less that the family apartments were arranged
longitudinally. I rather suspect that this arrangement was vertical, or
perhaps vertical and transverse. This surmise is given, however, for
what it may be worth. Windows I could not find, although small apertures
undoubtedly existed in all the outer walls, both for light and for air.

The chambers being all very much ruined, the lower ones filled with the
stones and decayed ruins of the superposed stories,--of these stories
themselves but part of the walls, denuded and often twisted,
remaining,--I have not been able, with one single exception, to secure
or even see any of what we would call the "furniture." Small fragments
of grinding-stones (_metates_) are sparsely scattered over the entire
ruins, otherwise the only object of daily use as articles of furniture
met with by me has been a hearth, which I found or dug out _in situ_, in
room _I_, and which, complete, forms part of the collections sent by me
to Cambridge.

The place where this hearth was situated is marked on the diagram in
room _I_. It stood on the floor against the north wall, and is composed
of three plates of stone, originally ground and polished (as the
specimen found in building A will show, which is a fragment only), and,
judging from new fragments found, of diorite or other hornblende rock.
There are three plates,--a basal one, 40 m.--16 in.--long and 20 m.-
