Some excursions to the south-east led to the discovery of some more fresh water and well-grassed pastoral country, and the natives directed him to a crossing-place in that portion of Lake Torrens that had been sighted in 1845, by Messrs. Poole and Browne, of Captain Sturt's party. Babbage, however, failed to find the place, and lost his horse in the attempt to cross. In 1857, a Mr. Campbell made an excursion to the west of Lake Torrens, and discovered a creek with fresh water in it, which he called the Elizabeth. He finally came to Lake Torrens which he found in the same condition as other explorers had done--surrounded by barren country. In April of the same year, a survey in the country where Babbage had been exploring was conducted by Deputy Surveyor-General Goyder, and he certainly got into the land of enchantment. A few miles north of Blanche Water he found many springs bubbling out of the ground, around a fine lagoon, and north was an isolated hill, which he named Weathered Hill. From the summit of this hill he had a fine specimen of the effect produced by refraction. To the north, or thereabouts, he saw a belt of gigantic gum-trees show out, beyond which appeared a sheet of water with elevated lands on the far side, while to the east was another large lake; all this, however, was but the glamourie of the desert. The gigantic gum trees dwindled down to stunted bushes, and the rising ground to broken clods of earth. But the greatest surprise was reserved for the time Goyder actually reached Lake Torrens, for he found the water quite fresh. He described it as stretching from fifteen to twenty miles to the north-west, with a water horizon; an extensive bay forming to the southward, while to the north a bluff headland and perpendicular cliffs were clearly discerned with a telescope. From the appearance of the flood-marks, Goyder came to the conclusion that there was little or no rise and fall in the lake, inferring therefrom that its size would absorb the flood waters without showing any variation of level. No wonder that the good people of Adelaide were overjoyed when they heard the news. The threatening desert that hemmed in their fair province on the north had been suddenly converted into the promised land. Colonel Freeling, the Surveyor-General, immediately started out, taking with him both a boat and an iron punt with which to float on these new-found waters. What must have been the public feeling when a letter was received from the Surveyor-General, saying that the cliffs the headlands, and the grassy shores, where all built up on the basis of the mirage. The elfs and sprites of this desolate region had been playing a hoax on the former party.
