to set out on his last forlorn expedition. About Lat. 12° 30' S. we saw the base beds of 
the Desert Sandstone resting on granite. At the south-west corner of Temple Bay we 
descended for about two hundred feet over the edges of the lower shelf of Desert 
Sandstone to the porphyry on which it rests. The Desert Sandstone comes down to 
the sea-level at Temple Bay. At Bolt Head, in Temple Bay, thirty feet of horizontal 
reddish sandstone lay uuconformably on a blue limestone, at least a hundred feet in 
thickness, and dipping at 45° to the east. 
Purther north the “Eemarkable Bed Cliff” of the Admiralty Charts showed two 
coal-seams, each a quarter of an inch in thickness, in the midst of red sandstone. 
As far north as Camisade Creek the thick upper bed of sandstone forming the Sir 
William Thompson Eange and the lower shelf continued to jjresent the same features, 
the top of the eastern scarp of the former, although only a few miles from the Pacific, 
being the watershed of the Peninsula. Camisade Creek and Bay, it may be mentioned, 
were so named from tho circumstance that here we had further trouble with blacks, 
who this time, in the middle of the night, threw, among others, a spear which went 
clean through the deltoid uuisclo on the right side o£ mj neck. 
An uncharted island, close to the coast, at a point bearing S. 26° W. from the 
south-east end of Fora Island, is of horizontal Desert Sandstone. At this point and 
at the^ mouth of Henderson Creek the red sandstone is highly ferruginons and has a 
pisolitic sti-ucture^ There is evidently a very gentle dip in tho sandstones northward 
from the Ccwron Eange, so that although the dip is almost imperceptible we gradually 
pass over higher beds. a j 
Among the intricacies of the swamps between the Escape Inlets and the Jardine 
iver ire found the sandstone to be brown and forruginous, with a pisolitic structure. 
Both sides of the Albany Pass are composed of nearly horizontal beds of sand- 
stone. Simdar beds of sandstone are seen in Mount Adolphus Island to the north. 
Towards Cape lork slates rise from beneath the sandstone. At Thursday and 
adjacent islands slaty rocks rise to a considerable altitude, but the Desert Sandstone is 
seen ui numerous headlands at the level of the sea. 
About a mile west of Mount Morgan, near Eockhampton, is a mass— 
^parently about a hundred and fifty feet in thickness -of horizontally bedded 
Desert Sandstone. It rests, at this point, apparently on a mass of diabasic dolerite,* 
bu in other places It may be seen lying on the upturned edges of quartzite and 
greywacke strata of Permo-Carbomferoiis age (like the Gympie beds) similar in 
character to those of the country ” round Mount Morgan. The base of the Desert 
Sandstone is a mass of fine volcanic dust, while the upper beds are coarsely gritty, and 
for the most part siliceous, varying from white to brown and red. I should judge the 
base of the formation to be about one hundred feet lower than the summit of 
Mount Morgan, or one thousand one hundred and twenty-five feet above the sea.
