From thence they went in H.M.S. Sulphur to Cape Knob and Dillon Bay, and on their return Mr. Roe went back by York to the Swan River.
In 1836, further exploration was made by Hillman and Williams between the Avon and Williams Rivers; by Moore and Drummond about the sources of Moore River, and by Lieut. H. W. Bunbury in the valley of the Williams, and between the sources of the Dale and the Murray. In 1837 the Governor went by the valley of the Murray to Kojonup; and that year is notable for the landing of Lieuts. Grey and Lushington on the North coast, and for the discovery, by them, of the beautiful and fertile valley of the Glenelg River. Grey, however, having been severely wounded in a skirmish with the natives, returned with his party to Mauritius, to restore his health and prepare for a fresh descent on the North coast. Meanwhile, Hillman with his party was surveying the country, and laying out a road from Perth to King George's Sound.
It was, indeed, for the purpose of connecting the scattered settlements in the new Colony, that most explorations were now made. The settlers in the South-West very naturally desired that the road from Perth to Albany should pass near their locations, and the journeys of Messrs. W. Nairn Clarke, R. H. Bland (afterwards Colonial Secretary), F. C. Singleton, and Lieut, G. E. Egerton Warburton, were continued for the three following years with that object. At this time, also, Captain John Scully made further exploration on the Moore River, as did surveyor H. M. Ommaney (formerly a lieutenant in the army), on the coast to the West of Busselton, while Clarke examined the coast and its inlets between King George's Sound and Point D'Entrecasteaux.
