with dip N. at 45°, make a low rise in the ground. One and 

 a quarter miles from Blinman there is a high and bold ridge 

 of slaty dolomitic rock, somewhat broken in places, underlain 

 by shales: dip S.W. at 80°. Last prominent ridge, on the 

 east-ern side of road, in a direction N. 20° E., consists of 

 laminated shales, thin quartzites, and dolomitic rock in places. 

 At one mile from Blinman are shales, dip S.W., with broken 

 beds of slaty dolomitic rock. From this point the ground is 

 low, undulating, and grassy. 



IV. Blinman to Reap -hook Range. 



Trip southward (4 miles) to Reap-hook Range. So called 

 from its resemblance to the tool — a handle, and great curve 

 for blade. Also known as Patterton Hill and Mount Emily. 

 Drove out to Patterton Spring and then went one mile across 

 to Reap-hook Range. Tlie latter has a very striking rock 

 face 500 ft. in height. The top beds consist of 25 ft. of 

 impure arenaceous limestone having a vertical scarp : dip 

 E. 25° S. at 5°. Beneath which is a steep scarp of purple 

 shales and laminated flaggy shales. The latter are also seen 

 at the Patterton Spring (mentioned above), where they dip 

 S. 20° E. at 10°. In retracing my steps, on foot, from the 

 Springs to Blinman, underlying the slates, just mentioned, is 

 a dolomitic rock, then a limestone which weathers with a 

 dark-coloured smooth surface, similar to the Archaeocyathinae 

 limestone, but has arenaceous lines in relief that follow, 

 generally, a circular outline; then an arenaceous limestone, 

 showing an outcrop of about 100 yards, with dip at a low 

 angle. A thin quartzite occurs in the limestone series, which 

 is underlain, again, by thick arenaceous limestones; then 

 ochreous limestone with vein of siderite. For the next half- 

 mile there were noted calcareous beds, separated by thin 

 beds of shale; then quartzites and calcareous grits: dip S.E. 

 at 12°. 



There follows a relatively flat country, in which shales 

 are first met with, then solid limestone showing wavy struc- 

 ture and is sometimes arenaceous, which continues to small 

 creek, three-quarters of a mile before reaching Youangera 

 Spring. On the Blinman side of the creek another strong 

 limestone is seen on a prominent rise, just before sharp bend 

 in the road (between Sections 64 and 69), with shale on top 

 and is underlain by quartzite, with a dip S.E. These beds 

 are followed by a somewhat lower hill, consisting of flaggy 

 shales ; and then, strong calcareous grits passing into brecci- 

 ated limestone, which latter makes a bold ridge that crosses 

 a creek that is tributary to the Blinman Creek, about a 

 quarter of a mile above the road crossing. Some fine springs 

 occur in the creek a few yards above the crossing.
