from it to the western corner of portions 27 and 28, Parish of 

 Stanhope, is 120^°. The coal is uncovered there, in the creek, for 

 about six feet, and Mr. Drinan assured me that the seam used to 

 outcrop at a position he pointed out to me, but which is now 

 covered with debris; this point is some 10 to 15 yards further 

 downstream. As the seam is dipping about south at 16°, this would 

 indicate (if the two points represent outcrops of the same seam) a 

 thickness of approximately 11 to 13 feet of coal and bands. This 

 thickness corresponds very well with that mentioned above, and 

 the two outcrops (Kangaroo Creek and Billy Brook) are probably 

 of the same seam. As this outcrop (Billy Brook) was under water 

 at the time of my visit, it was not possible to obtain specimens 

 suitable for analysis, but from the pieces which could be got, the 

 coal appears to be a hard, bright, bituminous coal of good quality. 

 The position and extent of the actual outcrops depend on weather- 

 conditions a good deal. Between my two visits to Kangaroo Creek 

 (about three months apart), there was considerable rain, and much 

 of the outcrop, as lirst seen, was covered with soil washed down the 

 creek-bank. 



At a number of other points in the neighbourhood, pieces of coal 

 have been observed, washed into the creeks after heavy rains, e.g., 

 in Eui Creek above Mr. Peter's house, in portion 12, and in Billy 

 Brook about portion 10, Parish of Stanhope. That these come 

 from the same measures, there is no doubt, but the outcrops are 

 probably covered over by surface-soil. The outcrop in Billy Brook 

 is due to the creek having cut down through the overlying sand- 

 stone, isolating a part of it, and exposing the Greta Coal-Measures 

 along the creek-bed. (See Section, Fig. 1, p. 148). 



(iii.)The Upper Marine Series. — Above the Greta Coal-Mea- 

 sures, there is a series of massive sandstones and conglomerates. 

 Marine fossils are very scarce in them, but, in the lower part, frag- 

 ments of a Conularia (C. inornata) were found. These sandstones 

 are, then, probably the equivalents of the lower part of the Branx- 

 ton beds of the Upper Marine Series. The following is a vertical 

 section of the Permo-Carboniferous rocks, as developed in this 

 area (Pig. 1, p. 156).
