From Port Augusta the Flinders range runs almost northerly for nearly 200 miles, throwing out numerous creeks (I must here remark that throughout this work the word creek will often occur. This is not to be considered in its English acceptation of an inlet from the sea, but, no matter how far inland, it means, in Australia a watercourse.), through rocky pine-clad glens and gorges, these all emptying, in times of flood, into the salt lake Torrens, that peculiar depression which baffled Eyre in 1840-1. Captain Frome, the Surveyor-General of the Colony, dispelled the old horse-shoe-shaped illusion of this feature, and discovered that there were several similar features instead of one. As far as the Flinders range extends northwards, the water supply of the traveller in that region is obtained from its watercourses. The country beyond, where this long range falls off, continues an extensive open stony plateau or plain, occasionally intersected with watercourses, the course of the line of road being west of north. Most of these watercourses on the plains fall into Lake Eyre, another and more northerly salt depression. A curious limestone formation now occurs, and for some hundreds of miles the whole country is open and studded with what are called mound-springs. These are usually about fifty feet high, and ornamented on the summit with clumps of tall reeds or bulrushes. These mounds are natural artesian wells, through which the water, forced up from below, gushes out over the tops to the level ground, where it forms little water-channels at which sheep and cattle can water. Some of these mounds have miniature lakes on their summits, where people might bathe. The most perfect mound is called the Blanche Cup, in latitude about 29 degrees 20', and longitude 136 degrees 40'. The water of some of these springs is fresh and good, the Blanche Cup is drinkable, but the generality of them have either a mineral salt- or soda-ish taste; at first their effect is aperient, but afterwards just the opposite. The water is good enough for animals.
