JOURNEY FROM 
tion, sloping outwards from the top, of twenty feet in length by 
twelve, which appears to have served both as a tower and a 
buttress. 
The measurements are here given in the rough, but they will be 
found in detail by a reference to the ground-plan and elevation ISTo, 9, 
in the plate containing the details of some of the forts which have 
been noticed in the course of the journey. 
In some instances we found wells in the trenches surrounding the 
forts, at others, within the outer walls ; and more frequently without 
the forts altogether, among traces of building in their immediate 
vicinity. T. he remains of building last mentioned were sometimes very 
considerable ; but the ground-plans alone of these are now extant, 
from which little more may be collected than that the chambers 
were built in squares, ranged in line with some attention to regula- 
rity, though differing a good deal in size. Tombs are occasionally 
found excavated in the neighbourhood of such forts as are built on 
a rocky soil; but we never were fortunate enough to find any thing 
in them which could point out decidedly the mode of burial which 
had been adopted. Some of these were entered by wells of different 
depths, and others by approaches cut in the rock, sloping down from 
the upper part of the door, like those in front of the Kings’ tombs 
at Thebes. 
The remains about Ghimenes and Imshaila may answer to those 
of the Diachersis Preesidium of Ptolemy ; but we are not aware of 
any remains which may be pointed out on the coast as those of the 
Turris Herculis, or of the Diarrhoea Portus, of this geographer. 
When we had arrived within a day’s journey of Bengazi, the wea-
