On, on he went all day, and still the footprints showed here and there. Night came, and again he was forced to rest and wait for the light. He was colder than ever, he shivered violently, and longed for the warmth of the sun. That night he never slept at all, and he rose in the early morning light stiff and tired. His head felt light, his limbs ached, and the one thing he could think of coherently was Chlorie.
Suddenly all traces of the marks vanished. He hunted high and low, but all to no purpose; they ended as abruptly as if the pursued had been snatched up into the heavens.
Two nights and two days he wandered to and fro. He was chilled to the bone, and was in a high fever. At last he had to give in, and lay under the shelter of a tree. The warmth of the sun revived him, and he crawled weakly to a bush on which grew luscious plums, ate his fill and slept. When he awoke he felt better and stronger. Perhaps he had been dreaming—the footprints _must_ go on. But no, they came to an end at a grassy edge, and there was no mark to show that human beings had passed that way. He spent that day hunting for a sign of the fugitives, but was unsuccessful, and wearily retraced his way to the air bird.
The scenery was beautiful. The island rose to a chain of peaks in the centre, and beautiful passes and wooded valleys led through the mountains to the further side. The vegetation was purely tropical. Palms, breast high, grew to the edge of the sea shore; the undergrowth showed no sign of any animal inhabitants; not a twig was broken, not a leaf trampled upon, to mark the passage of a foreign body. Alan made the return journey quickly, and soon found himself at the edge of the bush. But the “Chlorie” had gone! There were the signs of where she had rested; the mark on the sand of her wheels; an oily patch on the ground showing where her engines had been lubricated—but all sign of her had vanished. Had Waz-Y-Kjesta failed him, or had Chlorie returned? He felt in his pockets—there was a scrap of paper and a pencil. “I am going inland,” he wrote. “If you come back, search for me. Alan.” He pegged it to the ground close to where the Chlorie had been anchored, and turning his face westwards, retraced his footsteps.
