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.

The Honourable Sir Thomas Elder’s sheep, cattle, horse, and camel station, Beltana, is the first telegraph station from Port Augusta, the distance being 150 miles.  The next is at the Strangways Springs, about 200 miles distant.  This station occupies a nearly central position in this region of mound-springs; it is situated on a low rise out of the surrounding plain; all around are dozens of these peculiar mounds.  The Messrs. Hogarth and Warren, who own the sheep and cattle station, have springs with a sufficiently strong flow of water to spout their wool at shearing time.  The next telegraph station beyond the Strangways is the Peake, distant 100 miles.  About twenty miles northward, or rather north-westward, from the Peake the mound-springs cease, and the country is watered by large pools in stony watercourses and creek beds.  These pools are generally no more than twelve to fifteen miles apart.  The waters in times of flood run into Lake Eyre, which receives the Cooper and all the flood waters of West and South-western Queensland, and all the drainage from the hundred watercourses of Central South Australia.  The chief among the latter is the huge artery, the Finke, from the north-west.

The Charlotte Waters Station, named after Lady Charlotte Bacon, the Ianthe of Byron, which was to be my last outpost of civilisation, is a quadrangular stone building, plastered or painted white, having a corrugated iron roof, and a courtyard enclosed by the two wings of the building, having loop-holes in the walls for rifles and musketry, a cemented water-tank dug under the yard, and tall heavy iron gates to secure the place from attack by the natives.
