became more loose and drifting, and not a blade of grass, or any species of vegetation, was visible, rendering hopeless any attempt to cross it with horses.  This point of the lake shore, being by Mr. Eyre’s chart about thirty miles to the westward of where I found it, I thought it advisable to push further north, in the direction of the highest point of the range, 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 which they were intended to last, having already nearly expired.
