together iir 1885 the Aneroid gave the level of Charleville as 1,190 feet. Although the 
latter reading must be wrong, it may bo retained for the sake of comparison, as it 
was one of a series taken all along the rente from Brisbane to the G-rey Range. At 
Millie Station, on the W ard River, our Aneroid read 1,120 feet. The southern 
extremities of Desert Sandstone tablelands were seen to the north of the Adavale 
road, between the Nive and Ward Rivers, and between the Ward River and Middle 
Creek. The bases of these tablelands would probably bo about 1,200 feet above the 
sea, by our reckoning. 
Between Ambatalla Creek (1,190 feet) and Emu Creek (1,025 feet) the road 
crosses a Desert Sandstone tableland (the Paroo Range), which extends from north to 
south and is seven miles in breadth. The base of the sandstone is 1,080 feet and its 
summit 1,280 feet above the level of the sea. The difference in the vegetation of the 
tableland and of the surrounding “ Rolling Downs ” is most marked. The “ Downs ’’ 
a,re well grassed and covered in places with mulga and gidyah trees, while the Desert 
^andstone has only low brushwood and is almost destitute of grass. The Paroo Range 
is a spur of the W arrego Range, which divides the heads of the Bulloo River from the 
heads of the Barcoo. Opals are said to be abundant iir the range at the head of 
Pleasant Creek. I have been reliably informed that the northern part of the range 
is capped by a lava-form bed of basalt. 
The Town of Adavale (1,000 feet) is built on a cemented gravel or conglomerate, 
apparently derived from the waste of the Desert Sandstone. 
Between Adavale and Milo Station, on the Bulloo (fifteen miles north-north- 
west of Adavale), is a low tableland of Desert Sandstone. About two miles north of the 
station a spring rises from a fine-grained hardened sandstone rock (Desert Sandstone?), 
and even in the terrible drought which prevailed at the date of our visit gave an estimated 
yield of one and a-half cubic inches per second. This spring is about 1,030 feet above 
the sea and twenty feet above the station. At the base of the Desert Sandstone table- 
land, west of the station, the Manager, Mr. Beck, informed me that there are springs 
capable of watering four thousand sheep in the driest season. In a well in the north- 
west corner of Britomart Block, thirty miles west-south -west of Milo Station, a well was 
being made through the Desert Sandstone. The section was described by the sinker as 
follows : — 
Feet. 
Yellow and brown sandstone [Desert Sandstone] 138 
Blue-grey clay shales, with indistinct plant remains [Rolling Downs] 19 
167 
Brackish water was met with at fifty feet ; the supply is only about six hundred gallons 
per day. 
The direct road from Adavale to Windorah, on the Thomson River, crosses the 
Desert Sandstone tableland in Lat. 25° 50' S. North of the road the tableland bifurcates, 
the western limb being known as the Cheviot Range, and the eastern limb retaining the 
name of the Grey Range. The public-house “ Jack on the Rocks” affords a welcome to 
the weary bushmau near the summit of the range, although rather on the Barcoo fall. 
A shallow well near the house collected, even in the terrible drought of 1885, sufficient 
soakage water from the Desert Sandstone to supply the house. Mr. Beck informed me 
that springs break out — (1) At the base of the sandstone at the bifurcation of the Cheviot 
and Grey Ranges (head of Coouabiila Creek) ; (2) in Oxford Downs Block, halfway up 
the range ; (3) in the same block on the top of the range ; (4) at the base of the Grey 
Bange, near the head of Durilla Creek ; and (5) round the base of an isolated tableland
