By far the most important journey yet accomplished for the exploration of Australia, is that of Dr. Leichardt. This gentleman, accompanied by Mr. Gilbert, a naturalist, and six others, started from Moreton Bay, on the southeastern shore of the island, in October, 1844, to penetrate to Port Essington, on its most northerly point; in order, if possible, to open a direct route to Sydney. Several months after the party left, reports were brought to Moreton Bay that they had been cut off by the natives. This was proved to be untrue by an expedition sent out for the purpose, who traced the travellers four hundred miles into the interior. Dr. Leichardt found it impossible to penetrate into the interior in a direct course, on account of high table-land, and the absence of water; and this circumstance compelled him to keep within six or seven degrees of the coast. Their six months' provisions being exhausted, the only resource of the party was the horses and stock bullocks,--and with these the strictest economy was necessary. One was killed as provision for a month--sometimes a horse, at others a bullock. For six months prior to reaching Port Essington, the party were reduced to a quarter of a pound of meat per day--frequently putrescent--unaccompanied with salt, bread, or any kind of vegetable. In the neighborhood of the Gulf of Carpentaria, Mr. Gilbert, the naturalist, was surprised by the natives, and killed. The remainder reached Port Essington on the 2d of December, 1845.[58] The narrative of Dr. Leichardt's expedition has not yet been published in detail. The report[59] which has appeared consists chiefly of notices of the geography of the region traversed, the soil, productions, climate, &c. He encountered natives in many places, sometimes in considerable numbers. By some they were kindly received, by others treated as enemies. Their characteristics are not noticed. The most extraordinary feature in Dr. Leichardt's narrative is the constant succession of water. Although the season was an exceedingly dry one, no rain having fallen for seven months, yet from the commencement to the close of his year and a half's expedition, throughout the whole length and breadth of the vast region he traversed, he was continually meeting with fresh water, in the forms of "pools, lagoons, brooks, wells, water-holes, rocky basins, living springs, swamps, streams, creeks or rivers." The soil in many places was of the best kind, covered with luxuriant grass and herbs. Of the former, some twenty kinds were seen. In lat. 18° 48´ he found a level country, openly timbered, with fine plains, extending many miles in length and breadth. The flats bordering the creeks and rivers were covered with tall grass, and the table-lands presented equally attractive features. "The whole country along the east coast of the Gulf of Carpentaria is highly adapted for pastoral pursuits. Cattle and horses would thrive exceedingly well, but the climate and soil are not adapted to sheep.
