56 NOTES ON THE CONGLOMERATE, ETC. 



strike east 7 degrees south and west 7 degrees north, with a 

 northerly dip. 



Following the creek down the gorge, sandstones are met 

 with, either in dtu or in detached blocks, until the top of the 

 waterfall is reached. The creek here falls a considerable 

 distance over a platform of very hard altered sandstone. 



From this point there is a somewhat steep ascent up the side 

 of the crescent-shaped hill on the northern side of the creek, 

 which is about 400 feet above the bed of the creek. Con- 

 glomerate is met with on the side of the hill, and the summit of 

 the range for a considerable distance consists of conglomerate. 

 It is not possible to get the strike and dip of the beds here, but 

 the probability is that they are dipping at high angles. Whether 

 there is any connection between the two beds of conglomerate 

 on either side of the creek is difficult to decide, and in any case 

 there must be more than one bed of conglomerate, because there 

 is a marked difference in many respects between the large- 

 grained conglomerates on the hilltops, and the smaller 

 conglomerates found on the sides and at the foot of the range 

 on both the Walsh and Wild rivers. 



Descending the crescent-shaped hill into the Wild Eiver 

 Valley, nothing but fragments of sandstones and conglomerates 

 are found, either in the watercourses, or on the ridges. 



In two small watercourses, which rise in the range just 

 described, and run down on either side of the Sports Ground 

 Eeserve, nothing but fragments of sandstone and conglomerate 

 are visible, until close to their junction with Grant's Creek, 

 where an outcrop of the porphyry of the Herberton series is 

 exposed. On the Herberton side of Grant's Creek the 

 conglomerate series is absent, and the rock, wherever it is 

 exposed, belongs to the Porphyritic series. 



Further to the north a track running up Bon Accord Creek 

 presents the same geological features. The porphyry can be 

 seen in the bed of this creek near its juncture with Grant's 

 Creek, and can be traced some distance up. 



Proceeding along the track, the point where the porphyry 

 gives place to the sandstone is readily seen. Further up the 

 creek, the shaft of the Bon Accord Claim is sunk close to the 

 junction of the sandstone with an elvan dyke, which can be
