Away from the river the two beds of limestone, Nos. 20 and 21, arc separated by 
a hollow (denoting the prevalence of soft rocks, probably shale.s), in which debris of 
shale or slate, and lump.s of manganese oxide and hematite, can be seen in the soil. 
Both beds of limestone are covered on the top with bottle-trees. These beds cross 
the road about three miles north of the river, and contain numerous caves, in some of 
which gold has been obtained on washing the detritus on the floor. 
As the whole of the strata comprised in the above section are evidently part of 
an unbroken series, and the limestone beds have, from their fossil contents, been 
identified with those of the Burdoliin Bods, the whole thickness (20,782 feet) must be 
considered as belonging to the same division of the Devonian rocks. How much more 
would be added to this by following the Broken Eiver down to its junction with the 
Clarke, I cannot say. 
I'rom the Broken Eiver the Pentland and Gilbertou road runs north-west to 
McKinlay’s (twenty miles). Two miles beyond the “ Limestone Wall ” (bed No. 20 in 
the above section), the road crosses soft, white, yellow, greenish, and liver-coloured 
sandstones, with partings of grey and occasionally liver-coloured shales ; then a six-feet 
bed of limestone-conglomerate, containing pebbles of limestone (chiefly), sandstone, 
and conglomerate, in a limestone matrix. The limestone pebbles are masses of coral. 
This singular conglomerate strikes north-north-east to south-southwest, and is succeeded 
to the north-west by red shales. Por the next mile the road crosses grey sandstones, to 
which several thin beds of limestone succeed. Thence to McKinlay’s the road crosses 
gritty yellow sandstones. 
About a mile north of Paudanus Creek (on which McKinlay’s Station is situated) 
is a thick bed of limestone, said to be traversed by an antimony lode. Prom 
McKinlay’s north-west for about eight miles (across the divide between the Burdekin 
and Einasleigh waters) the road crosses several beds of limestone alternating with 
brown and white sandstones and red shales. After seventeen miles more, in which no 
strata crop up on the road, basaltic rocks are met with, which continue for at least fifteen 
miles more to the Lynd Station, on Lee Creek, a tributary of the Einasleigh. It is 
probable that the basalt overlaps the stratified rocks just described. 
The whole of the stratified rocks, which include several beds of limestone, met 
with along the road north-west of the Limestone W all in all probability belong to the 
same series as the limestone in the wall itself. Some of the sandstones and liver-coloured 
and greenish shales remind one strongly of the shales above the Panning Limestone. 
In returning, in December, 1880, to Townsville from the Croydon G-old Piold, 
via Greorgetown, I took the direct road from the Lynd Station to Townsville, which 
crosses the Clarke Eiver at the Telegraph Station near its mouth. Eight miles from 
the Lynd Station the basalt country comes to an end. In two miles more the divide, 
here almost imperceptible, between the Einasleigh and Burdekin waters is crossed. 
Granite is seen on the road for the next three miles. To the granite succeed twelve miles 
of mica-schist country, with numerous quartz reefs. After two miles of basalt the valley 
of Paddy’s Gully is reached. The gully is in mica-schist, which extends along the 
road half-a-mile on either side of the gully. Then comes half-a-milc of stony basalt 
country ; then two miles of mica-schist and two of basalt ; thence to two miles short 
of Gray Creek (five miles) mica-schist is met with. I regard the mica-schists met wdth 
between this point and the divide as of an older date than the Broken Elver Limestone 
and associated strata. 
At the point (two miles short of Gray Creek) where the mica-schist is seen for 
the last time, strata similar to those on the Pentlaud road, north-west of the Limestone 
Wall, are met with. The first eight miles are over red shale.s, partly jasperised. As far
