Nevertheless, we must not forget that there are dense masses of red and variegated sandstones and clays, thousands of feet in thickness, and of vast horizontal extent, wholly devoid of saliferous or gypseous matter.

Sir Charles Lyell
I find since that Dr Wilson states these rocks to be highly saliferous, and says the Arabs scrape them with knives to obtain saltpetre for making their rude gunpowder.
"Byeways in Palestine"
James Finn
You have only to cover the desert with pale-green saliferous bushes, no higher than a man's knee; quite a scanty covering will do, so that in the thickest places plenty of sand may still be seen; and there should be barren patches to represent the low sand-hills and the smooth clay-pans.
