not been able to conquer. Water-holes existed, however, in the 
upper part of the eastern creeks, and swampy lagoons seemed to 
become numerous down the Isaacks, which joins the sea very 
probably near the Mackenzie, in Broad Sound. The Upper 
Suttor partakes of the character of the Isaacks; and as it was by 
far more accessible from the head of the latter than from its own 
lower course, 1 have placed it in the second division of my journey, 
though it belongs to the system of the waters of the third. 
If, at a close examination, a sufficient quantity of water should 
be found, a wide extent of country will be opened to the squatter, 
who will travel with his herds without difficulty over the level 
country along the Isaacks and its tributaries, and will ascend on 
gentle ridges to the plains of Peak Range, and probably still 
farther to the westward, beyond another range of peaks, which we 
perceived in that direction. He will stock the beautiful country 
at the head of the Isaacks and the Suttor, over which at present 
numerous flocks of emus roam ; and will fill with animation that 
immense tract of country which spreads out round the foot of 
Coxen’s Peak. 
During the month of February, till March, we were favoured 
with frequent thunder-storms, from the west and south-west, 
which enabled us to pass along the driest part of the Isaacks; and 
after having left the Mackenzie, we enjoyed every night a strong 
refreshing breeze from the northward, which set in at half-past 
eight o’clock at the Mackenzie, but every day earlier as we passed 
Peak Range and travelled along the Isaacks to the north-north¬ 
west. During the day, gentle easterly and north-easterly breezes 
prevailed. 
3. The third division of my journey comprises the Lower 
Suttor, the Burdekin, and the country intervening between the 
latter river and the Lynd (the upper part of which is more acces¬ 
sible from the east than from the westward). It extends from 
latitude 21° to 18°, and is characterised by its supply of running 
water, by its primitive rocks, its limestone, its numerous ranges, 
and its fine open well-grassed forest. 
If you bear in mind that it comprises three degrees of latitude
