The next year, Collie and Dale, removed to King George's Sound, proceeded to explore that district Collie from Oyster harbor about the King and Kalgan or Trench River, as it was then called, and the Porongurup Range, while Dale was sent to Tood-e-rup, a part of the Stirling Range, to search, but without success, for a cereal plant said to be used as food by the natives. This year also, 1831, Mr. J. G. Bussell examined the country between the Blackwood and the Vasse, as well as the coast to the West of those rivers.
In 1833, Mr. Alfred Hillman, a surveyor in the employ of the Government, explored the South coast from Albany as far as Nornalup inlet. In 1834, Mr. G. F. Moore made the junction of the Avon and Swan; Mr. Thomas Turner ascended the Blackwood; Mr. John Butler explored the Lake district to the North of Perth; Mr. C R. B. Norcott, Superintendent of Police, the Murray River valley; Mr. F. Ludlow traversed the country between Augusta and the Swan River; and Mr. W, K, Shenton, a draughtsman attached to the office of the Surveyor General, examined the Collie River.
In 1835, Hillman visited the Avon, Hillman, and Williams Rivers; Mr, Patrick Taylor examined the upper course of the Kalgan and Hay; Surveyor Thomas Watson the Murray; and Moore the Upper Swan; but that year is most notable for the expedition under the command of the Governor himself, attended by the Surveyor General, which, traversing the country about the head waters of the Murray and Blackwood, struck the course of the Palinup or Salt River, and returning from the West of the Stirling Range (so named after Governor Stirling), descended the valley of the Kent, and proceeded along the coast to King George's Sound.
