For the first time since she had shaken off Gaston she began to think seriously. What she had done was madness. She had no food for herself or her horse, no water, and Heaven alone knew where the next well might be. She was alone in an uncivilised country among a savage people with no protection of any kind. She might fall in with friendly Arabs or she might not. She might come across an encampment, or she might wander for days and see no one, in which case death from hunger and thirst stared her in the face. What would she do when night came? With a sharp cry she leaped to her feet. What was she to do? She looked all around the little oasis with startled eyes, at the few palm trees and clumps of camel thorn, the broken well and the grey horse still snuffing about its mouth. She felt frightened for the first time; she was alone and about her was unending space, and she felt an atom, insignificant, the least of all things. She looked up into the clear sky and the blue vastness appalled her.
