Our great exertions in walking over the rock-strewn ground soon began to create acute thirst. We had no fluid now of any kind, and only a dozen lozenges were left. These we shared, three to each; and very soon the cravings for moisture triumphed and they were gone. We had nothing whatever now to assuage thirst! We must find water, or die! Times without number we consulted together as to the propriety of throwing away our arms and ammunition; but still we continued to carry them, first in one hand, then in the other. Then one or the other of us said he could go no farther, and begged the rest to leave him to die in peace. But we cheered and rallied him whose hopes of deliverance were ebbing, as best we could, and still toiled on. Upwards! onwards! filled with all the torments of a raging thirst, we toiled, our feet heavy as though shod with lead; but still no sign of life--the same desolate wilderness, the same hot sun, the same bare rocks and stony way, continuing on and on apparently to eternity! All that livelong day we struggled on beneath a scorching sun. Towards evening we were startled by a shout from Sandy: "The water! Doctor, the shining water! See, there! There! below ye on the left." We looked where Sandy pointed, and there--could we trust our eyes? or was it but the fancy of a scorched and sun-disordered brain?--there, about a mile away, was a beautiful pool below the hillside, its shimmering waters glistening like silver in the setting sun! We literally danced for joy, and, nerved to new strength by the sight of the welcome waters, we ran helter-skelter over the rocks and stones towards them. When two hundred yards away we threw down our rifles, and slipped out of the straps that held our burdens, and each raced as for his life to be the first to revel in the feast! Graham, being by far the strongest, reached the brink first; but instead of kneeling down to quench his thirst, he threw himself to the ground with a piteous groan of despair, saying: "We are lost! my comrades; we are lost! Unless we can cool our burning tongues with mercury!" Alas! Graham's words were only too true, for the lake, which must have covered some hundreds of acres of ground, was one thick, fluid mass of quicksilver! We sat down by this costly, yet horrid pool, too overcome with bitter disappointment, and with the exertion of hastening thither, to speak; and not one of us stirred until the sun had set and night approached. "Doctor," exclaimed Temple at last, in a weak and weary voice, "we can go no further; we had best remain here and die."
