84 Lectures on the Geology, Botany, frc., of the 
supply of water makes me suppose, that it forms a considerable 
stream towards the sea-coast.. It disembogues very probably at 
Broad Sound, in latitude 21° 30', as the natives pointed to the 
north-east, when we asked them about the course of the river. 
The country south-east of Expedition Range, between Zamia 
Creek and Erythrina Creek, was, for a great distance to the east¬ 
ward, flat and openly timbered. It was well grassed and tolerably 
well provided with water at the foot of the range. Its latitude 
was 24° 50', but the course of its waters seemed to be directed 
either to Port Curtis or to Keppel Bay. Should a practicable 
communication with the sea-coast be found, I have no doubt that 
this will become a valuable district for pastoral purposes, and that 
even the good country of Castle Creek, Robinson’s Creek, and 
Palm-tree Creek, will be accessible from this side. 
2. The second part of my journey, which extended from lat. 
23° to lat. 21° 40', comprising Peak Range, the Isaacks, and the 
Upper Suttor, bears a character very different from that of the first. 
Here a long range of noble peaks, composed of domite, extends 
far to the W.N.W., and offers to the west and south-west a wide 
view over basaltic plains and open downs, which alternate with 
low and openly-timbered ridges. To the eastward of those peaks 
basaltic ridges, with gently-undulating outlines, narrow plains 
and abrupt sandstone ranges, form numerous valleys, along which 
creeks descend to the eastward, winding in their lower course 
through an immense level country, and joining the Isaacks, which 
comes from the north-west, and forms the chief outlet of the 
waters to the sea. An open forest covered the whole district 
with the exception of some narrow belts of scrub along the Isaacks 
and on the sandstone ranges; and the most luxuriant grass 
clothed not only the black soil of the basaltic plains, but the stiff 
flats and the sandy bergs along the creeks and river. The supply 
of water was, however, not in proportion to the number or size of 
the channels; and it was on those magnificent downs of Peak 
Range that Mr. Calvert and myself nearly perished for want of 
water. It was here that we felt for the last time a hot wind, from 
the west and south-west, which direction points to that desert 
interior which even the persevering boldness of Captain Sturt has
