74 REPORT OF FIELD MEETINGS. 



lying immediately beneath it. On the rocky shore close ■ by 

 the " Four-Fathom " limestone is again seen, but in this case 

 much folded and bent owing to its disturbance by the whin- 

 stone intrusion. A curious fold here is well known as the 

 "Saddle Rock," or sometimes as the "Grey Mare Rock." 

 The so-called Dunstanborough diamonds are not rare in 

 the whinstone hereabouts. They as well as the amethysts 

 which accompany them are, of course, merely good quartz 

 crystals formed in vugghy cavities in the stone. 



The best description of this bit of coast is, I think, 

 Professor Garwood's in Vol. II. of the " History of North- 

 umberland." 



The Fourth Meeting took place at Stanhope on Sept. 

 8th, Only two members arrived by the morning train, and 

 decided to take their own way instead of following the pro- 

 gramme. The morning was devoted to Parson's Byre 

 Quarry. Here it was found that the glacier floor, with its 

 fine example of smoothed and striated rock, had been nearly 

 entirely quarried away. In the quarry itself the water 

 channels, vertical and horizontal, and the various posts of the 

 limestone were examined with much interest. Several good 

 fossil shells were obtained, and a large Orthoceras was noted, 

 too heavy for removal. The afternoon was spent in Stanhope 

 Dene, where another member turned up. Nothing was 

 observed here that calls for record.
