Study of Child Growth and Development, and to be used in longitudinal studies of 
child development; 3) identity photographs on almost every individual for whom 
we have a blood sample, for later correlation with human biological results and 
for growth studies; 4) ethnographic background material to aid in interpretation 
of genetic and medical findings, and for a general understanding of their 
cultural setting; and 5) photographs documenting the natural history and ecology 
of the islands for use in epidemiological studies and studies of disease 
ecology. 
IV. Child Drawings 
Several hundred drawings were collected from children in most of the Island 
groups studied. We have recorded the name, age, sex, and village residence of 
each of the child artists. The child's depiction, frequently in a culturally 
stylized manner, of his island world and the activities within the village and 
on the sea, provide a useful and unique document for the study of child growth 
and development. These drawings are being used together with the large 
collection of drawings from different cultural and linguistic groups in 
Melanesia, especially New Guinea, Polynesia and Micronesia which we have 
accumulated from children in low-acculturated societies over the past 20 years 
in the study of culturally determined symbolic styles and patterns of cognitive 
function. 
V. Recording of Music 
Ten hours of island music, dancing, and communal singing were recorded on 
magnetic tape, and will be used largely as supplementary material to the corpus 
of cinema and flash and still photography. On several Islands we had the 
opportunity to make high-quality recordings of traditional Polynesian and 
Melanesian dance-songs and commemorative chants, which will become intersting 
ethnographic supplements to the studies of the human biology of these islands. 
VI. Collection and Documentation of Ethnographic Artifacts 
Several hundred tools, household articles, and ceremonial carvings were 
collected in the villages and district centers which the expedition visited. A 
principle aim of the photography during the expedition was to supplement this 
collection with a photographic record of several thousand artifacts in their 
village setting, particularly in reference to house architecture and settlement 
pattern, the use of indigenous tools, native art styles, tattoo patterns, canoe 
construction, traditional dress, and the techology of gardening, irrigation and 
food preparation. 
The collection and documentation of these artifacts will provide an 
ethnographic picture of the living conditions and dietary habits of the 
islanders, and will be important as background cultural data for studies of 
child rearing and disease patterns on the Islands. The documentation of 
cultural styles of art and technology will also be useful as supplementary data 
to the medical studies of genetic distance among the Island populations 
studied.
