future with pack-horses only.

It was A.C. Gregory's arrival in Adelaide with pack-horses from his last
expedition down the Barcoo that had led to this change of tactics.
Charles Gregory, who had accompanied his brother, was now engaged by the
Government to overtake Babbage and acquaint him with their intention, but
when he reached Port Augusta, Gregory took it upon himself to order the
drays home, Babbage being away surveying. Babbage overtook them and
ordered them back; but pleading Government orders, they refused to
return. Babbage wrote to the authorities pointing out the unfairness of
their action, and, mustering up a small party, returned to continue his
work with six months' provisions.

On this occasion, Babbage gave more time to discovery than he had done
before. He went out beyond the boundaries of his survey, and pushed on to
Chambers Creek, so called by Stuart, who discovered it while Babbage was
busy at Lake Gairdner. Babbage traced Chambers Creek into Lake Eyre, and
was thus the first discoverer of this lake, which he called Lake Gregory.
He found a range which he called Hermit Range, but from its crest
discerned no sign of Lake Torrens, thus settling a certain limit to its
extension to the north. He made further explorations to the west of Lake
Gregory, now Lake Eyre, and found some hot springs. Meanwhile, during the
time he was making these researches, the Government had, in a very
high-handed manner, appointed Warburton to supersede him. Warburton
started out to find Babbage, taking Charles Gregory as his second.
Failing to find him at the Elizabeth, he followed and overtook him at the
newly-discovered Lake Gregory. Warburton made a few discoveries while
seeking for Babbage, amongst them the Douglas, a creek which was
afterwards of great assistance to Stuart, and the Davenport Range; and he
also came upon some fair pastoral country.

Babbage's surveys and explorations had done much to clear up the mystery
and confusion that had hitherto obscured the geography of the salt lake
region. His discovery of Lake Eyre (Gregory) and of the complete
isolation of Lake Torrens, reduced the component parts of that huge
saline basin to some sort of method and order. In addition to these
achievements, Surveyor Parry made some further discoveries both of fresh
water and available pastoral country to the eastward of the Lake.
