THE SEPARATE EXCAVATIONS IN GHIAUR KALA. 193 
side, towards which the floor is gently inclined. It consists of a channel put 
together with red brick fragments and covered at the top. It is continued in a 
clay pipe. The upper edge of this pipe stands at about the same level as the 
bottom of the basin. Thus the discharge has a proper fall and was in all proba- 
bility a part of a drainage system. The remains of such pipe-systems were also 
found at other points in the excavation, similar clay pipes occurring in different 
depths (3 feet 4 inches and 8.5 feet) on the longer side of the pit (fig. 427). 
After the removal of the construction just described, the excavation was 
deepened by the establishment of two terraces, respectively 15 and 8 feet long, 
at the respective depths of 11.5 feet and 17 feet. An older layer was reached 
at a depth of 20 feet 5 inches, where, in the southeast corner of the digging, there 
stood a cylindrical pithos 7n 
situ, 
Still deeper, at 23 feet 4 
inches, was found the head 
of a female clay figure. At ; 
a depth of 27 feet, work was Se LTP, 
stopped on June 7. 
It is naturally of interest 
to compare the culture lay- 
ers opened upon the plateau 
of the outer city with those 
of the acropolis hill. The 
pottery found in outer dig- 
ging I is the same in all the 
layers and corresponds to 
that of the upper digging. 
We must therefore refer the 0 5 10 15 20 25 30 FEET 
plateau and the acropolis 
hill, in so far as they have 
been explored, to the same 
great culture epoch. The numerous coins found in outer digging 1 will aid in 
determining the age of this epoch.

OUTER DIGGING II. 
For the characterizing of this culture, the supply-vessels found in outer 
digging 11 are of great significance. (See the special report of Homer Kidder.) 
They belong to the same class as the large marginal fragments of the upper digging 
which were covered with inscriptions. These finds will be discussed later. 
GALLERIES I TO III. 
The examination of the galleries, which were intended to penetrate the heart 
of the acropolis at different levels, led to no decisive results. In the two upper 
galleries, I and I, it was necessary to cut through very thick walls of sun-dried 
bricks, but very few pottery fragments were brought out, and these, as regards 
form and workmanship, belong to the same pottery as that from the upper digging.
