She shook her head and looked up piteously, with tears in her wonderful eyes, as she made a great sacrifice to her honour.

He gave a great shout as he leapt to the saddle and took the stallion back a hundred yards, then wheeled him and raced him back along his tracks.

"Understand, beloved?" he cried, as he bent as he rushed past her at full speed and lifted her to the saddle. "There is nothing to understand." And he turned the stallion as he spoke and headed him towards the tents. "We will just go back, dear; we will just pass to say goodbye—together."

And they swept across the desert.

Then he reined in the stallion and sat staring, then whispered, as he bent and kissed the bonny curls:

"The way out, dear; the way out. Someone is waiting for us."

Stubbornly, heavily, across the desert, with occasional pauses for rest and investigation of the track of small footprints, and the horizon, came Wellington.

He was very hot and very thirsty, and it seemed to him that he had been walking for many days through many, many endless deserts, but he intended to criss-cross the Sahara, or any other desert, through all eternity, until he could deliver the book he held between his formidable teeth to his beloved mistress.

And she slid from the saddle, and knelt, and put her arms around him, and took the somewhat moist keepsake from him.
