which I imagined was probably his Mount Serle; for though it was
not to be expected that Mr. Eyre, whose principal and almost sole object
was to discover a road to the interior, would, at the same time, have
been able to lay down the position of his route with the same accuracy
that might have been expected from a surveyor; this difference of
longitude prevented my being certain of the identity of the spot, or that
the range on our left, might not after all, be another long promontory
running to the north, similar to that on the western side of which was
Mr. Eyre's course. The appearance of the country, however, from the hills
close under Mount Serle (for the perpendicular cliffs on the east side of
this range of hills prevented my ascending to their summit without
turning them among the ranges, for which I had not time), convinced me at
once, from its perfect accordance with the description given by Mr. Eyre,
that his eastern arm of Lake Torrens was the sandy desert I had left, its
surface being about three hundred feet above the level of the sea; and
our two converging lines having thus met at Mount Serle, I knew it was
useless to advance further in the same direction to a spot which he had
named, from the impossibility of proceeding beyond it, "Mount Hopeless."

"I was thus forced to return to Pasmore River, as the nearest point from
whence I could cross to the low hills to the eastward, south of Lake
Torrens; and from thence I sent back to the depot two men of the party,
and three horses--the former for the sake of their rations, and the
latter on account of the probable difficulty I should have in procuring
water--taking on with me only Mr. Henderson and Mr. Hawker on foot, with
the light cart and one policeman. The second evening I made the most
northern of these hills, but could not find a drop of water in any of
them; and having unluckily lost the policeman, who had crossed in front
of the dray and got entangled in the dense scrub, I was detained three
days riding upon his tracks, until I had traced them to our dray tracks
from the depot at the Black Rock Hill, which he reached in safety, after
being out five days without food. The cart, in the mean time, had been
obliged to leave the spot where I left it, for want of water--having been
out six days without obtaining any but what we carried in the kegs; and
when I overtook it, we had not sufficient provisions for another attempt,
the period of one month, for whic
