 existence of foiir, and possibly five, so placed is due to more 

 than coincidence.

 what they regarded as the most important directions, namely, 

 one 30° west of north and one due south. 30° east of north 

 appears to have been also of great importance, but not 

 perhaps quite so great as the westerly line. My first idea,

 to verify this. There was so thick a fog that I could hardly 

 see across the " circle." I have, however, found that the mid- 

 summer sunset in the latitude of Arbor Low takes place about 

 40° west of north, so that the theory appears untenable. 



But is it possible that when the site of Arbor Low was 

 selected the sun did rise and set 30° east and west of north
