Babbage rode one hundred and sixty miles before he overtook him at Mount Remarkable, and there learned that the South Australian Government had changed its official mind with regard to the conduct of the expedition, and had decided that it should be conducted in 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.
