Nothing to go on. But any sufficiently isolated and desolate spot would do. Almost anywhere along the southern edge of the continental islands should serve. The plane roared on monotonously, while Bell began to wrestle with another and more serious problem. In three days--two, now--an American naval vessel would turn up, with scientists and chemists on board. It was to be doubted whether anything like an overt act would be risked by that vessel. If all the governments of South America were under The Master's thumb, then cabled orders from his deputies would race three navies to the spot. And the government of the United States does not like to start war, anywhere. Certainly it would not willingly enter into a conflict with the whole southern continent for the solution of a problem that so far affected that continent alone. The Master's kidnapping had solved nothing, so far. * * * * * Jamison tapped his shoulder. "No pursuit, so far," he observed coolly. "I've looked." Bell nodded. "They don't dare. Not yet, anyhow. They're depending on The Master. How is he?" "Smiling peacefully to himself, damn him!" snarled Jamison. "Do you know what we're up against?" "Ourselves," said Bell coldly. "But I'm nearly licked. He's got to talk!" Jamison moved away again. The earth below looked as if it had been torn to shreds in some titanic convulsion of ages past. The sea was everywhere, and so was land! There were little threads of silver interlacing and crossing and wavering erratically in every conceivable direction. And there were specks of islands--rocks only yards in extent--and islands of every imaginable size and shape, with their surfaces in every possible state of upheaval and distortion. A broader mass of land appeared ahead and to the left. "Tierra del Fuego again," muttered Bell. "If we cross it...." For fifteen minutes the plane thundered across desolate, rocky hills. Then the maze of islets again. Bell scanned them keenly, and saw a tiny steamer traveling smokily, for no conceivable reason, among the scattered bits of stone. The sea appeared, stretching out toward infinity. Bell rose, to survey a wider space. He swung to the left, so that he was heading nearly southeast, and went on down toward that desolation of desolations, the stormy cape which faces the eternal ice of the antarctic. He was five thousand feet up, then, and scanning sea and earth and sky.... And suddenly he swung sharply to the right and headed out toward the open sea. He felt a small figure pressing against his shoulder. Presently fingers closed tightly upon his sleeve. He glanced down at Paula and managed to smile. "There are some rocks out there," he told her quietly. "Islands, I think, and Diego Ramirez, at a guess." * * * * *
