24 PROBABLE OUTCROP OF BLYTHESDALE BRAYSTONE, 



of stratigraphical or paleontological evidence, the assertion that' 

 such was indeed the case wonld be hard to contravene. 



But there is such a great lithological resemblance between 

 this outcrop and the Braystone, that their possible indentity 

 would be worth inquiring into. The outcrop is a great addition 

 to the already known water-absorbing areas, whatever it may be, 

 and its course across the country parallel to the known course of 

 the Braystone, and its position in the Mt. Elliott strata, would 

 justify a further exploration of the outcrop with a view to estab- 

 lishing its indentity with the Blythesdale Braystone. I am not 

 at present able to explore further, nor am I likely to be able to- 

 do so in the near future, but the search is worth prosecuting. 



My attention was called to this deposit by Mr. Lambert, of 

 Bedford, and the deposit presents a striking appearance viewed 

 from the side of the mountain. It resembles a local " White 

 Terraces," and is tunnelled and eroded to a depth of forty feet. 

 These sheer walls, seen from the mountain side, appear fiat like 

 a sea of sand. From this outcrop is probably due much of the 

 white sand of the IMaranoa channel. 



The same rock, as far as one can judge from lithological 

 resemblance (in the absence of stratigraphical or paleontological 

 evidence), breaks out at the " Chalk Water-holes" on the Angel- 

 lala Creek, also at the " Apple-tree Camp" on the same creek; 

 also at a cave about 7^ miles N. of Mt. Maria ; also, according 

 to Mr. Connolly, of Angellala Downs, at the head of Duck-pond 

 Creek. Hence it will be seen that this deposit runs a course 

 parallel Avith the Blythesdale Braystone, but, if identical Avith the 

 Braystone, widens its outcrop some 32 miles in breadth, as it 

 appears fully that distance S. and W, of the supposed Braystone 

 boundary. Samples of the stone referred to have been forwarded 

 to the Geological Museum. Mt. Lonsdale, Redcap, and 

 McManus's Gap present, I am told, outcrops of this same rock. 

 I am awaiting an holiday long enough to visit these localities. 

 Whether Braystone or not, this rock is remarkably fitted for 

 water-absorption and extends in a broad belt over the country, 

 its derived soil being covered by a vegetation very distinct from 

 the j\Iulga ridges of this region. The ant-hills and the soil are 

 greyish yellow or white, not red as further west.
