Note B — Chapter VII

The Inca Indians of the Sierra region possess the same extraordinary faculty of transmitting intelligence without apparent material means that the Hindoos and the Arabs have. Thus, during the last revolution in Peru, the fall of Lima was known to the Indians of Bolivia on the southern shore of Lake Titicaca three days after it happened, though the telegraph wires were cut and all ordinary communications suspended. Without the telegraph this would be quite impossible by any means known to Europeans.
