has probably been brought up from some considerable depth, as 

 there would be nearly 3,000 feet of Permo-Carboniferous strata 

 between this horizon and the underlying' Carboniferous rocks. 



►Some distance to the east of Lochinvar Railway Station, there 

 is a large mass of basic rock, which is on a horizon about 2,700 

 feet above the base of the marine beds; this, then, probably belongs 

 to the same series as the volcanic rocks round Blair Duguid. In 

 the opposite direction, to the north-west, the conglomerate seems 

 to die out quickly, and give place to a thicker development of the 

 Harper's Hill Sandstone, for there is no outcrop of the conglomer- 

 ate on the main road to Singleton, going up Harper's Hill. Fossils 

 are very numerous in these beds; in the railway-cutting, just over 

 half a mile east of Allandale, there is a bed about 2 to 3 feet thick, 

 composed mostly of the remains of thick shells like Eurydesma 

 cor data and Platyschisma. The following is a list of fossils from 

 these beds: —
