was only an interlude.

Soon after he was again associated with the same navigator on another voyage to the north-western coast. Still two more expeditions to the same coast were undertaken and successfully carried out within the next two years. The results in every case were highly successful, and the boundaries of science gained further extension from these enterprises.
Having spent four years on these voyages with King, Cunningham became inoculated with the spirit of adventure, and thirsted for an exploit on his own account. The feat he proposed to himself was to open a practical route from Bathurst to the Liverpool Plains. This splendid district, as already narrated, had been discovered by Oxley three years previously; but he ha<l entered it from the western side—so to speak, by the back door—on his journey from the marshes of the Macquarie. The discovery had, consequently, been useless, and the Liverpool Plains were as yet known only by name. Sir Thomas Brisbane, the Governor of the day, entered heartily into Cunningham's scheme, having clearly understood the importance of the object in view. Orders for an equipment were issued to the full extent of the explorer's requirements. All things being ready by the 31st of March, 1823, the party, consisting of the leader, with five
