During the 1950s and 1960s the Commonwealth Scientific and Industrial Research Organisation (CSIRO) was investigating resources in Papua New Guinea on a broad scale using both air photography and checking "ground truth". As a Botanist with the CSIRO Division of Land Research and Regional Survey, carrying out scientific and terrain exploration in many areas PNG, Mr Pullen wrote regular letters to his wife which are detailed, observant and witty. Mr Pullen's letters clearly conveys his impressions of the country and the people as well as giving a clear account of his botanical survey practices.
