Lieutenant Roe attempted several journeys to the eastward, and discovered many salt lakes on the tableland of the interior. Messrs. Bunbury, Wilson, and Moore made other explorations, more or less succeeding in the purposes they had in view; but they all embraced so small an area, and so little details have been preserved, that they cannot take any important rank in the history of continental explorations. During the twenties another settlement had been formed on the northern coast of Australia; but one not destined to drag out a very long existence. Captain Gordon Bremer, in the TAMAR, accompanied by two transports, sailed through Torres Straits and anchored in Port Essington, in 1824. The port was, however, at that time condemned as a site for a settlement, the supply of fresh water did not come up to expectations, and the dry months of the year had set in. Bremer sailed for Melville Island, one of twin islands lying off the coast. These islands, Melville and Bathurst, are separated from each other by a narrow strait that Captain King, the discoverer, mistook for a river. On Melville Island a favourable site with abundance of fresh water was found, and the usual routine of taking possession and forming an encampment gone through, and for a time things seemed to prosper; the soil of the island is good, and tropical fruits would flourish with little trouble; but hostilities commenced with the blacks, sickness broke out, and in 1829 it was determined to abandon the settlement, and since that date no attempt has been made to colonise this island, although it is now stocked with the increase of the buffaloes left behind by the TAMAR'S people. Fort Wellington, in Raffles Bay, founded in 1826, fared no better, although controlled during its last year by the gifted and unfortunate Captain Barker. A blight of stagnation seemed in those days to hang over all attempts at settlement in the tropical regions, and in three years' time Fort Wellington was abandoned, and with it the northern coast. Once more we must turn our attention to the southern watershed of the Darling, and the additional links of discovery in the great network of its tributaries.
