the territories of the British tribes before the Roman 
Conquest ; secondly, those which were made by the 
Romanized Britons ; thirdly, the marsh ditches thrown up 
by our ancestors after the English colonization of the 
island. “ Wansdyke,” says Collinson, “ exists to this day 
in many places in perfect preservation—one of the greatest 
curiosities of antiquity. It commences at Andover in 
Hampshire, and thence passes in nearly a straight direction 
to Great Bedwin, within the confines of Wilts, near which, 
upon its track, have been discovered celts and instruments 
of war.” I cannot but think that this is an error in the 
historian of Somersetshire. The second Belgie boundary, 
according to Dr. Guest, “included the valleys of South 
Wilts, and then swept round so as to separate the downs 
of Hampshire from the woodlands which eneircle Scott’s 
Poor, and the remains of the boundary-line called the 
Devils Ditch, near Andover, and at Walbury (which 
Collinson calls Wansdyke) must be assigned to this period, 
rather than considered portions of Wansdyke”’ On the 
confines of the Forest of Savernake it seems to take its 
beginning; and on the wild Marlbro’ Downs it appears, as 
Collinson observes, “ in its pristine state, exceedingly deep, 
and flanked by a very lofty mound, attracting by its sin- 
gular appearance the attention of the cenrious traveller.” 
A curious feature in its course is that from the border of 
Savernake Forest it bends to the south, as if to avoid 
Avebury, and approaches close to, but does not include, 
Bath. 
“It seems reasonable to infer from this,” says Dr. 
Guest, “that when the line of demarcation was drawn, 
the Dobuni insisted on retaining their ancient temple and 
their hot baths ; and if'this inference be a just one, another 
and a more important one seems naturally to follow :
