Perhaps it was as well I did not know the whole truth, else the complete despair which the knowledge must have produced might have driven me out of my senses. As it was, the intervals of despair already endured had ever alternated with glimpses of hope; and this had sustained me, until I became more able to look my terrible fate in the face. I continued to cry out, sometimes for minutes at a time, and then only now and again, at intervals; but as no response came, the intervals between my spells of shouting became longer and longer, till at length, resigning all hope of being heard, I allowed my hoarse voice to rest, and remained silent. For several hours after this, I lay in a sort of half stupor--that is, my mind was in this state, but unfortunately my body was not so. On the contrary, I was racked with severe bodily pain--the pain of extreme thirst--perhaps the most grievous and hardest to endure of all physical suffering. I never should have believed that one could be so tortured by so simple a thing as the want of a drink of water, and when I used to read of travellers in the desert, and shipwrecked mariners on the ocean, having endured such agonies from thirst, as even to die of it, I always fancied there was exaggeration in the narrative. Like all English boys, brought up in a climate where there is plenty of moisture, and in a country where springs or runlets exist within a few hundred yards of any given point, it is not likely I should ever have known thirst by experience. Perhaps a little of it at times, when at play off in the fields, or by the sea-shore, where there was no fresh water. Then I had felt what we ordinarily call thirst--a somewhat unpleasant sensation in the throat, which causes us to yearn for a glass of water. But this unpleasantness is very trifling, and is almost neutralised by the anticipation we have of the pleasure to be experienced while allaying it; for this, we know, we shall be able to accomplish in a very short time. Indeed, so trifling is the annoyance we feel from ordinary thirst, that it is rare when we are compelled to stoop, either to the ditch or the pond, for the purpose of assuaging it. We are dainty enough to wait, until we encounter a cool well or some limpid spring. This, however, is not thirst; it is but thirst in its first and mildest stage--rather pleasant from the knowledge you have of being able soon to remove the pain. Once take away this confidence--become assured that no wells nor springs are near--no ponds, ditches, lakes, nor rivers--that no fresh water is within hundreds of miles of you--no fluid of any kind that will allay the appetite, and then even this incipient feeling of thirst would at once assume a new character, and become sufficiently painful to endure.
