One of the first efforts to reach the centre of the continent was made by Edward John Eyre, in after-days Governor of Jamaica. He left Adelaide in 1840, his party consisting of five Europeans and three natives, with thirteen horses. But the year was one of drought. The great marsh, now called Lake Torrens, was a sheet of glittering salt. The horses broke through the crust, and a hideous and tenacious black mud oozed out. Advance on this line was impossible; and, upon taking a more westerly route, the explorer was stopped by the still larger marsh now called Lake Eyre, which was also a deceptive sheet of salt. Disappointed, Eyre returned to the head of Spencer's Gulf, and decided to make a dash at Western Australia, following the line of the cliffs in order to intercept any rivers. Alas, there were none to intercept! The party had to depend for subsistence upon the chance of finding water-holes not dried up, and the little clay pans formed by the aborigines, and called native wells. At an early stage Eyre sent all his party back, except his overseer Baxter, his black boy Wylie, and two natives. The farther he went the more sterile the country became, and the worse was his position. The burning sand suffocated the travellers, and day after day passed without water. Most of the horses died. Eyre was watching the remnant feeding on some scanty vegetation one night, and was musing on his gloomy prospects, when he heard a musket shot. The two natives had murdered the overseer, decamped with the stores, and left Eyre and his boy Wylie to their fate! The night was dark, and Eyre gives a vivid description of his feelings as he sat in the gloom by the side of the corpse of his friend, expecting every moment that the treacherous blacks would use their muskets upon him and Wylie. He could not bury the body, for the ground was hard rock, and he had no tools. Day after day he plodded on. Had Wylie deserted him he must have perished, for in the boy's quickness in detecting traces of the natives and indications of their 'wells' lay the only chance of safety. At last, when nearly exhausted, Eyre saw two boats at sea. They belonged to a French whaler. Eyre was taken on board, was well fed, was supplied with stores and ammunition; and, after a rest of eleven days, he and Wylie continued their journey, and, the country improving, they reached King George's Sound in safety. Thirty years after this journey was made it was repeated from the opposite side by Mr. John Forrest, a fine young West Australian explorer, who with a small party passed over it with but little inconvenience or difficulty. Mr. Forrest again and again camped on Eyre's old camping ground, which he recognised at once, and which seemed to have remained undisturbed from the time Eyre and Wylie left it.
