Io6 SOME NOTES ON ARBOR LOW AND OTHER LOWS. 



is worth comparison witli a section on an exactly parallel line 

 from Hare's Hill (Section No. 3). 



I should like to draw special attention to this direction, 

 30° west of north. 



On its way this line from Arbor Low passes close by, but not 

 exactly through, two lows on Chelmorton Low, and between 

 two lows below Brown Edge called Lady Low and Cow Low. 

 It also runs through the curious amphitheatre in Deep Dale 

 called Churn Hole. I note this as the parallel section from 

 Hare's Hill to Axe Edge and the Shining Tor runs through 

 the Shining Ford. The words " Churn " and " Shining " are 

 not common in place names. 



If we produce this line the reverse way, 30° east of south, it 

 passes through the low just outside the embankment or vallum, 

 and a little further on through the traces of another low, which 

 has been destroyed. This line is the transverse axis or greatest 

 diameter of the approximate ellipse formed by the stones of 

 the " circle." The greatest diameter of the stone " circle " on 

 Castlerigg, near Keswick, is also on this line. 



Let us now take the other side of the equilateral triangle, 

 which gives us a line pointing 30° east of north. At first sight 

 it appears to pass through the summit of Longstone Edge, a very 

 noticeable pointed hill and nothing else ; but if we produce the 

 line the reverse way (30° w'est of south), and stoop down in the 

 ditch, we shall find that the centre of Arbor Low, the top of the 

 vallum, the peak of Longstone Edge, and the crest of Stannage 

 Edge against the sky line, are in a uniform gradient (see section 

 No. 2) ; and this line is also almost exactly horizontal. More- 

 over the line passes through the biggest stone of the whole lot, 

 numbered X by Mr. Gray. This stone is perforated ; and when 

 it was standing it is more than probable that the perforation 

 was also in the same line of sight. In other words, the points 

 named are in the same vertical plane and in the same horizontal 

 plane. 



It is obvious that any two points must be in the same straight 

 line. The odds against three points being in the same straight
