In Search Of Water
LAKE SALINAS ends the string of lagoons connected with the Sierras Ventana and Guamini. Numerous expeditions were formerly made there from Buenos Ayres, to collect the salt deposited on its banks, as the waters contain great quantities of chloride of sodium.

But when Thalcave spoke of the lake as supplying drinkable water he was thinking of the RIOS of fresh water which run into it. Those streams, however, were all dried up also; the burning sun had drunk up every thing liquid, and the consternation of the travelers may be imagined at the discovery.

Some action must be taken immediately, however; for what little water still remained was almost bad, and could not quench thirst. Hunger and fatigue were forgotten in the face of this imperious necessity. A sort of leather tent, called a ROUKAH, which had been left by the natives, afforded the party a temporary resting-place, and the weary horses stretched themselves along the muddy banks, and tried to browse on the marine plants and dry reeds they found there-- nauseous to the taste as they must have been.
