The whole scene partook more of enchantment than reality, and as the eye wandered over the smooth and unbroken crust of pure white salt which glazed the basin of the lake, and which was lit up by the dazzling rays of a noonday sun, the effect was glittering, and brilliant beyond conception.
[Very similar appearances seem to have been observed by Monsieur Peron, on the S.W.coast near Geographe Bay.

"A cette epoque nous eprouvions les effets les plus singuliers du mirage; tantot les terres les plus uniformes et les plus basses nous paroissoient portees au dessus des eaux, et profondement dechirrees dans toutes leurs parties; tantot leurs cretes superieures sembloient renversees, et reposer ainsi sur les vagues; a chaque instant on croyoit voir au large de longues chaines de recifs, et de brisans qui sembloient se reculer a mesure qu'on s'en approchoit davantage."-- VOYAGE DE DECOUVERTES AUX TERRES AUSTRALES REDIGE PAR PERON.] Upon regaining the eastern shore, I found that all I had been able to effect was to determine that the lake still continued its course to the N.W.that it was still guided as before, by a ridge like a sea shore, that its area was undiminished, that its bed was dry on the surface for at least six miles from the outer margin, and that from the increasing softness of the mud, occasioned by its admixture with water, as I proceeded there was every probability that still further west, water would be found upon the surface.

Beyond these few facts, all was uncertainty and conjecture in this region of magic.

Turning away from the lake, I retraced my steps towards the depot, and halted at dark after a stage of nearly forty miles.

Here was neither grass nor water, and again I was obliged to tie up the unfortunate horses, jaded, hungry and thirsty.
During the night, I released one of the poor animals for an hour or two, thinking he would not stray from his companion, and might, perhaps, crop a few of the little shrubs growing on the sand ridges, but on searching for him in the morning he was gone, and I had to walk twelve miles over the heavy sand tracking him, the boy following along our outward track with the other horse, for fear of missing the man who was to meet us with water.
The stray horse had fortunately kept near the line we had followed in going to the lake, and I came upon him in a very weak and miserable condition, soon after the arrival of the man who had been sent to meet us with water.
