limestones make a great development on the northern part of 

 the hill, with a dip N. 20° E. at 23°. The limestone has 

 a concretionary structure and is very brittle with a spheroidal 

 fracture. The limestone is underlain by shaly flags. At a 

 quarter of a mile further the road crosses the tributary stream 

 again, at a bar formed by another limestone that is impure, 

 carrying streaky lines and reticulations of an earthy nature, 

 in relief, as well as small stones. This limestone outcrop is 

 53 yards wide, with a dip N. 20° E. at 30°. Within a few 

 yards it is followed by another limestone, quite as thick as 

 the preceding, and forms a scarp face which runs parallel to 

 the stream and road for IJ miles; the road then takes a 

 southerly turn. 



On the southern side of the great limestone series there 

 follow, in descending order, a thick series of flaggy shales 

 with ferruginous dolomitic limestones and grits in prominent 

 edges ([?]2 miles across the strike). The road rises to a 

 high point, where the shales dip N. 20° E. at 30°, and are 

 overlain by grits and a ferruginous dolomitic rock. 



Coming down the hill on its eastern side the strike swings 

 round a little, with a dip N.E. at 25°, which has the effect 

 of bringing the limestone once more across the road, where 

 the latter crosses a large creek. The road continues on the 

 line of junction between the limestone and shales for over a 

 mile. The road crosses the creek for the last, time, where 

 the shales have the same dip as in the last reading, viz., 

 N.E. at 25°. 



The road now curves round to the south towards Blinman. 

 Flaggy shales continue on low ground. About one and a half 

 miles from the Blinman Mine, situated near the road, in a 

 small wash, there are gritty rocks, much broken and twisted, 

 in an apparently vertical position, and, mixed with these 

 broken beds, is a deposit of small quartz crystals, separately 

 developed, making a width of 10 yards, and extends still 

 further in patches. 



About a mile from the Blinman Mine, on the western 

 side of the road, there is a great spread of gritty limestones 

 on the flat, making an outcrop 200 yards in width, underlain 

 by flaggy shales, best seen on the rise of the hill, having a 

 dip N. 30° E. at 25®. The same shales are seen in the creek 

 on the eastern side of the rise, with a dip N.E. at 27°. 

 The gritty limestone, just referred to, appears to be cut off 

 by a strike fault on the eastern side and is probably a repe- 

 tition of the limestone of the range seen to the north. The 

 disturbed strata in the valley (referred to above) may be 

 regarded as suggestive of such a fault. The associat-ed shales 

 pass up into quartzitic rocks on the rise, with shales on the
