At last, when the mountains appeared tantalizingly near, but when they were still nearly twenty miles away, it seemed as though the end had come. For two days neither men nor animals had tasted a drop of water. At the close of the second day, a slight elevation had disclosed a lake lying at their feet, glowing in the red beams of the setting sun. With feeble strength they had rushed to it, and flung themselves into its tempting waters. They were as salt as brine, and, with this bitter disappointment, came despair. They lighted fires and made coffee with the brackish water that oozed into holes dug in the salt-encrusted sand, but it sickened them, and they could not drink it.
