bed of the stream, and halted for the night. Camp 34.

MOUNT BRUCE.

3rd July.

Still returning on our old track, at five miles I stopped to ascend a
very remarkable hill which had formed an important point in the
triangulation of this part of the country, to which had been given the
name of Mount Samson. Sending the party onward to wait for me at camp 22,
I commenced the ascent of the mount, which proved something more than I
had calculated upon, as it occupied more than an hour's sharp toil to
arrive at its summit; when gained, however, it amply repaid the trouble,
as from it I could discern almost every prominent hill or peak within
sixty or seventy miles, and amongst them the mountain which on a former
occasion I had procured a bearing to from Mount Augustus, at a distance
of 124 geographical miles, and which I now named Mount Bruce, after the
gallant commander of the troops, who has always warmly supported me in
carrying out explorations. This part of the country I believe to be the
most elevated in north-west Australia--Mount Samson having an altitude of
not less than 1000 feet above the valley of the Hardey, while Mount Bruce
and the mountainous country to the eastward rose to a considerable height
above its summit, which, by comparisons from the aneroid barometer, would
give not less than 4000 feet for the elevation of those ranges. Having
completed my observations, I descended the hill with somewhat greater
speed than it took to climb it, and was met at the foot by Messrs. Brown
and Harding, who had waited for me with a horse. In less than an hour we
overtook the rest of the party at Camp 22, when the additional horses at
once drank up all the remaining water left in the rocks; resting,
therefore, less than an hour, we moved on, taking a north course, over a
very rocky but highly fertile country of trap formation, the grass just
now being much dried up. At sundown we halted in an open grassy flat, on
which no water could be found, although it is probable there is plenty in
the vicinity, as emus and cockatoos were numerous; one of the former
walked boldly up to the horses, and was fired at, but without effect.
