THE HEADS OF BOWMONT WATER 189 



The line runs across the hay meadow towards Kingseat Burn, 

 which it crosses and is there very distinct. After crossing, it runs 

 straight forward on a line almost parallel with Cheviot Burn. 

 It reaches and enters into an enclosure or camp (No. 13). Leaving 

 hy the opposite gate, it passes on, curving down to and crossing 

 Cheviot Burn, on the opposite side of which it cannot be traced. 

 But as higher up the glen there are at least two well-preserved, 

 though short fragments, the continuation should be looked for 

 in the direction of the head of Breamish water, up the bank, 

 of which there has already been identified a considerable 

 remain, which is the continuation of a line which comes 

 from beyond Wooler, and passes, and connects, with the great 

 fort or town at Greaves Ash. 



The forts and enclosures as given on the Plan or Map (Plate 

 V.) will now be briefly described. 



No. 1. Calroust Castles (see Plate VI ) the fort visited by 

 the Club, is a very large fort, forming naturally into two 

 divisions, probably that furthest to the north was thrown out as 

 an extension as the population increased. The walls facing Bow- 

 mont Water are very high in front, and with a little excavation, 

 the face of the original building can be seen. The Plan shows 

 the arrangement of walls and entrances which remain. A large 

 mound is thrown out from the north-west angle, and curves 

 round till the summit of a perpendicular line of crag running 

 nearly parallel with the side of the fort is reached. The top of 

 this crag was probably fenced, and the comparatively level area 

 between it and the fort would provide a good and safe en- 

 closure. The curious pocket-like enclosures inside the inner 

 walls of the fort, are difficult to understand as part of the 

 original plan. They may have been inserted at a later period 

 when the first purpose of the fortifications had passed away, to 

 form pens for cattle.^' There are no hut circles remaining. 

 The interior seems indeed to have been smoothed and put 

 under cultivation of some kind during the middle ages. Outside 

 the fort on the north and west are evidences of cultivation 

 at the same period. 



No. 2. A cluster of enclosures or homesteads very similar to 

 No. 12, which see. 



* At Greaves Ash there are suggestions of similar pocket-like 

 enclosures.
