The well toward which we were dragging ourselves was indicated on Ceghéir-ben-Cheikh's paper by the one word Tissaririn. Tissaririn is the plural of Tissarirt and means "two isolated trees." Day was dawning when finally I saw the two trees, two gum trees. Hardly a league separated us from them. I gave a cry of joy. "Courage, Tanit-Zerga, there is the well."
