Bunyip Land

Joe Carstairs is a boy on a farm in Australia. His father is a keen naturalist who, some years before had set off for New Guinea in search of specimens, and never been heard of again. Joe is old enough to mount a search expedition, and takes with him a local doctor and an aboriginal worker on his farm. They find themselves joined by a stowaway, Jimmy, whose father is a squatter nearby. The team sets off, arrives in New Guinea, hires some more porters, and travels guided by some sixth sense straight to where Mr. Carstairs has been kept a prisoner, along with another Englishman, who has lost his mind under the stress of his imprisonment. There are a lot of close shaves and tense moments, but will they achieve their end?
