TERSACED SLOPES IN NORTH TYNEDALE, O i 



strata, and broad cross-lines of culture, running at right angles 

 down the gentle declivity, another and second terraced slope, as 

 continuation of the same escarpment, occurs, of an equally de- 

 fined character, and about the same length. In height, the 

 ledges average five, three, eight, and the uppermost nearly 

 twenty feet, being in breadth about fourteen, twenty, and 

 twelve yards. These all face due west. One more example, 

 at least, may also be seen about fifty yards nearer to the castle, 

 where the carriage drive skirts a rounded hill of small elevation, 

 the western face of which has two terraces, ten and six feet 

 high, and twelve and eight yards broad. The different series of 

 terraces at Swinburne are very remarkable. 



Almost as singular is the secofid example of this group, half-a- 

 mile north of Wall village, and between it and the line of the 

 great Roman barrier. It lies facing the west, with an inclination 

 to the north, on a lower slope of the steep declivity of Wall 

 Camp Hill, and consists of four or five terraces, overhanging a 

 precipitous descent of nearly forty feet. The ridges breast the 

 brow of the undulating escarpment, and neither retain their hori- 

 zontality nor their parallelism during their course of more than 

 two hundred and fifty yards, four of them scooped out at the 

 northern end, as in the last example. They rise five, seven, 

 twelve, and four-and-a-half feet above each other, and are nine, 

 six, four, and five yards wide. The upper are much shorter than 

 the lower terraces, being adapted to the nature of the ground, 

 like the Steel series. On the gentle slope above, and in the level 

 space beneath, the whole surface is furrowed with traces of late 

 cultivation. 



The Ihinl and remaining series of terrace-lines of this group 

 may be distinctly seen from the Wall Camp Hill on the opposite 

 side of the valley. They lie on the slope of Warden Hill, be- 

 neath the great British Fort, facing nearly due east, near High 

 Warden House, and consist of three or four ledges, all more or 

 less distinct, from six to twelve feet high, and of a proportionate 

 width. The uppermost shelf, after running about sixty yards, 

 suddenly dips to a lower level, and continues for seventy or 

 eighty yards further, whilst two shorter terraces towards the
