SCOTLAND AND IRELAND 



sits within the chamber and looks in a direct line 

 along the passage one sees the Barnstone. 



A series of measurements and alignments have 

 been taken to connect the ' Maeshowe tumulus 

 with the Ring of Brogar. Thus we have already 

 seen that the distance from the Barnstone to the 

 Watchstone is the same as from the Barnstone 

 to the tumulus. Moreover, the Watchstone is 

 equidistant from the ring and from the tumulus. 

 Again, a line from the Barnstone to the tumulus 

 passes through the point of the midsummer sun- 

 rise and also, on the other horizon, through the 

 point of the setting sun ten days before the 

 winter solstice ; the line from the Watchstone to 

 the Brogar Ring marks the setting of the sun at 

 the Beltane festival in May and its rising ten days 

 before the winter solstice, while the line from 

 Maeshowe to the Watchstone is in the line of the 

 equinoctial rising and setting. These alignments 

 are the work of Mr. Magnus Spence ; readers 

 must choose what importance they will assign to 

 them. 



The Inverness type of circle is entirely different 

 from that of which we have been speaking. The 

 finest examples were at Clava, seven miles from 

 Inverness, where fifty years ago there were eight 

 still in existence. One of these is still partly 

 preserved. It consists of a circle ioo feet in 

 diameter consisting of twelve stones. Within 

 this is a cairn of stones with a circular retaining
