How Bomba saved the camp of Gillis and Dorn, rubber hunters, from a night attack by jaguars--how he trapped the deadly cooanaradi, the most dreaded serpent of the South American wilds, when it pursued him; his adventures with alligators and anacondas; the besieging of his cabin by the headhunters; how his friends of the forest came to his aid when he was fearfully beset; all this is narrated in the first volumes of this series, entitled: “Bomba, the Jungle Boy; or, The Old Naturalist’s Secret.”
