INTRODUCTION TO VOLUME FOUR
HE three books gathered under the title "In Search of the Castaways" occupied much of Verne's attention during the three years following 1865.

The three great regions form the sub-titles of the three books which compose the story. In each region the rescuers meet with adventures characteristic of the land. They encounter Indians in America; bushrangers in Australia; and Maoris in New Zealand. The passage of the searching party gives ground,—one is almost tempted to say, excuse,—for a close and careful description of each country and of its inhabitants, step by step. Even the lesser incidents of the story are employed to emphasize the distinctive features of each land. The explorers are almost frozen on the heights of the Andes, and almost drowned in the floods of the Patagonian Pampas. An avalanche sweeps some of them away; a condor carries off a lad. In Australia they
