" The stones of the smaller circle (except Nos. 9, 11, 17, 19, in 

 Sir. R. Hoare's plan) are an aggregate of quartz, felspar, chlorite 

 and horn-blende. 



" No. 9 is silicious schist. 



"Nos. 11, 17 19 are hornstone, with small specks of felspar and 

 pyrites. 



" The altar-stone is a fine-grained micaceous sandstone." 



The Rev. W. D. Conybeare, in the Gentleman^s Magazine, vol. 

 ciii., part. 2, p. 4>5:i, thus speaks of the small circles : " Each stone 

 a variety of greenstone rock which occurs nowhere nearer than the 

 environs of Dartmoor in the West, or Charnwood Forest in Leicester- 

 shire on the North ; — either being a distance of full a hundred miles 

 in a direct line." 



Professor Andrew Ramsay, writing to Dr. Thumam (1859), says : 

 " The greenstone may possibly come from Devonshire, but such 

 rocks are also plentiful in Montgomeryshire, in Caernarvonshire, and 

 in Merionethshire, and around Snowdon. In fact from Cader Idris 

 to Moel Hebog, near Bedgellert and Snowdon, and from thence by 

 Carnedd Llewelyn to Conway. They also occur in North Pembroke- 

 shire. My friend, Mr. Perkins, the Vicar of Wootton-under-Edge, 

 considers that these blocks which are quite foreign to the district 

 may have been more easily brought from Brittany, where, I believe, 

 such rocks occur, and I think this is possibly the ease.'*'' 



Mr. Charles Moore, F.G.S., of Bath, in 1865, expressed his 

 belief "that the nearest point at which they could find similar material 

 was Wales, or possibly Shropshire, although he found stones of 

 precisely similar character while exploring the Mendips a few months 

 ago, but the stones could not have been obtained from that spot, 

 for the rock had never been worked."

so full of a grey pibble stone of great bigness as is not usually seene ; they 

 breake them, and build their howses of them and walls, laying mosse betweene, 

 the inhabaitants calling them Saracen's stones, and in this parish a myle and 

 halfe in length, they lye so thick as you may goe upon them all the way. They 

 call that place the Grey -weathers, because a far-off thty looke like a flock of
