Lost in the Wilds of Brazil

Two young companions join their fathers and a group of naturalists on an expedition into the Brazilian wilderness to photograph and collect specimens. The party meets jungle hazards—predators, giant snakes, disease, and rough terrain—becomes scattered, and the youths face capture by a hostile indigenous band; they endure desperate escapes, daring rescues, and violent confrontations while exploring deserted villages and wild country. Episodes alternately emphasize thrilling survival action, vivid natural-history description, and the boys' resourcefulness and courage, culminating in a hard-won reunion and a hasty flight from danger.
