upon hostile ground, they never think of fighting till they first 
make their camps, which they do not rear up at a venture, or 
without rule.” 
The constructive methods exhibited are interesting, being in 
many respects in contrast with those now in use. The formation 
of the streets does not bear out the common conception of a 
Boman road. Generally, it consists of a thick bed of gravel, hard 
and well bound together. The crown is well raised, and the 
gravel formation is retained at either side by means of two courses 
of stones, laid flat, one over the other; and outside these are 
the water channels, composed of stones 18 inches broad, and in 
lengths of 2 feet to 4, having the gutters about 9 inches wide and 
4 deep, cut with a square section out of the solid. In the 
case of the subsidiary streets only one line of gutter, placed at or 
near the centre of the roadway, is found. At several points con- 
tinuous channelling of this description, several stones in length, 
remains in situ. 
The surfacing of the northward portion of the longitudinal 
street is different, for, over a similar bed of gravel, it is paved 
with whinstonue cobbles, but the work is much disturbed. At a 
depth of 12 inches another similar surfacing is found, the cobbles 
used being somewhat larger. In this case, however, the water- 
channel is in the centre of the roadway, and is composed of a flae 
for the bottom, with the sides constructed of stone kerbine. 
This latter formation rests on forced ground about 18 inches 
deep; the streets towards the south rest on the natural till. 
The water-channels of the higher formation would thus seem, 
as regards position at least, to be secondary, and it may be that 
the channelling itself is also to be assigned to that period. 
The floor pavements in the station are of several sorts. With 
in the buildings examples made of squared and dressed freestone 
flaes, such as are in use now, are found. But the most common 
kind is the irregular polygonal pattern, patches of which are found 
in all parts of the area. It also is composed of freestone flag, but 
in small pieces, and the joints, instead of beine hewn, are hammer- 
dressed, so as the pieces may fit together on all sides. 
Numerous drains traverse the camp, of various dimensions and 
depths, but it is not ascertained on what system they are disposed 
Near the south end of the longitudinal street, one is found 8 feet 
in depth, measuring from the surface to the bottom. The drain
