While traversing Mt. Elliott, a peak to the south of Redford 

 Station, and lying slightly east from the divide between the 

 Warrego and the Maranoa Rivers, certain rocks were met with 

 which seem to indicate that the Blythesdale Braystone crops out 

 somewhat further south than was formerly noticed. 



The rock is beautifully clear and white, hardly even coherent, 

 and, whether the Braystone or not, is eminently suited for water 

 absorption. It presents great similarity to a water-bearing 

 sandstone found deep down in the celebrated " Boatman Bore." 



The mountain is capped with a coarse ferruginous grit, 

 probably of Desert Sandstone age. Underlying this is a band of 

 exceedingly porous white sandstone, then a small and vanishing 

 layer of shale, then the above mentioned porous white sandstone 

 to an indefinite depth. This order, I may remark, is exactly 

 Avhat seems to present itself in the Morven Bore. At a depth of 

 about 875 feet, about 10 feet of coarse ferruginous grit was 

 pierced, followed by about 300 feet of very porous non-coherent 

 white sandrock. But from the very nature of the sandstones 

 here, fossils are entirely absent, and paleontological evidence as 

 to the age of the sandstone beds is entirely wanting. The 

 Rolling DoAvns Limestone, so common about here, is missing in 

 the Mt. Elliott section. Sections are, from the nature of the 

 western country, very rare, hence the stratigraphical evidence is 

 not at all satisfactory. The outcrop referred to may indeed be 

 vonly a member of the Desert Sandstone series, and, in the absence
