Don’t trust those men with the strange plane. We think they are dangerous. We have heard them talking German. That was all. The note was not signed. Who were “we”? To this there was no answer. Jack felt a warm wave of friendliness sweep over him as he pocketed the note. Some one on this island wished to befriend him. A vision of the tall, slender girl whose roast pork had so excited the natives, and whose smile was most engaging, came before his eyes. She might have written it, he told himself. Then again, perhaps not. There might be white people hiding on the island. Who knows? Suddenly, as he rounded a coco plum bush, he caught a glimpse of that same girl. She was on her knees at the foot of a great coconut palm tree. Seems to be praying to the spirit of the palm, he thought, as he watched her from the shadows. He knew soon enough that his guess was poor. The girl was removing dried leaves and palm fronds from a spot at the foot of a tree. After throwing aside a square of brown canvas, she carefully lifted something white from its place of hiding. Jack could not see what this was, but he was not long in finding out, for the girl stood up and held before her a white dress. “An Army nurse’s uniform,” Jack whispered to himself. He shuddered involuntarily. In a twinkling, without removing her thin, one-piece garment, the girl had the white dress on, and a cap of white on her hair. After that, attired as a nurse, she did a strange little dance all by herself. Stooping over, she took a small square mirror from the hiding place. This she hung against the tree. Standing there, she surveyed herself in the mirror. Jack too, caught a glimpse of her face in the glass. Her dark face stood out strangely against the stark white of her dress. There was a curious look of animation and amusement on her face. Once she laughed, then shook her fist at the face in the mirror. Then, as her shoulders drooped in an attitude of utter sadness, she removed the dress and nurse’s cap, to return them to their hiding place. Realizing that she might come out on the trail at any moment, Jack hurried past the spot while she was covering her treasures. Jack hurriedly and quietly put some distance between them. His head was in a whirl. Who was this girl? Why had she come here, and how had she come into possession of the nurse’s costume? It was all very strange and disturbing. Dark forebodings took possession of him as he hurried along over the damp, heavily shaded path. CHAPTER XVI MOSTLY MEMORIES
