102 SOME ANCIENT BRITISH REMAINS. 



agricultural '* imi^rovers," is in every part of the country a 

 fruitful source of the destrviction of numberless relics of the 

 past. 



On the map * are recorded a series of boundary-banks, 

 extending from near the Zoological Gardens to beyond the 

 footway leading from the end of Worrall E/Oad across the 

 down to Rockleaze. These banks are easily traced for the 

 most part ; but there are additional lines faintly marked 

 here and there, about which there may be some doubt as to 

 whether they are not merely natural markings of the sur- 

 face ; these, therefore, are not entered on the plan. The 

 prevailing direction of the principal banks is from S.S.E. to 

 N.N.W. In this they agree closely with the majority of 

 those upon Dartmoor. The transverse banks, which con- 

 nect the longitudinal ones, are shorter, and less regular in 

 direction. One of the larger banks runs about 90 3''ards N. by 

 W. from near the tunnel-shaft at the top of Pembroke Road, 

 and is lost amongst some of the small superficial quarries 

 opposite the end of Worrall Road. Observation shows that 

 around these quarries, and the similar but larger ones which 

 run in parallel lines from S.W. to N.E., near Upper Belgrave 

 Road, there is little or no accumulation of earth and stones 

 in the form of heaps. What was excavated has practically 

 been all used for building or road-mending. This apparently 

 trivial point is nevertheless of importance when considered 

 in connection with the fact that in the series of shallow exca- 

 vations, which run across the top of the down from S.E. to 

 N.W. some distance to the west of the Pembroke Road 

 quarry, most if not all of the excavated material seems to 

 have been piled up around the hollows, and left there. 

 These pits are also mostly small in size, and many are 

 circular in outline. I believe them to be part of an ad- 

 '*= The scale of the map is 6 inches to 1 mile.
