Show Charcoal of Ancient Trees May Date Culture of Indians of the Middlewest i rotted all early timber and tree stumps except those which have been burned into charcoal. Doctor Hawley is gathering specimens speci-mens of tree cuttings and borings from standing trees and stumps. These specimens, with the charcoal found by university expeditions will be used to compile a "master chart" of the region. Indian culture of the Middlewest and of Illinois, which University of Chicago anthropologists have shown to have been in existence at least 2 000 years ago, may be dated definitely def-initely to the exact year by study of charcoal from old campfires and burned village sites, Dr. Fay-Cooper Cole, chairman of the university s department of anthropology, said in announcing a novel research proj- eCThe usefulness of the tree-ring method is now being determined by Dr Florence Hawley, recently appointed ap-pointed research associate in anthropology. an-thropology. Doctor Hawley, who has proved that the tree-ring dating method is workable by using charcoal char-coal found in mounds and campsites, camp-sites, this week began field activit.es in Wisconsin. Doctor Hawley's demonstration that charcoal remains of trees is as useful for dating purposes as are timbers and stumps, opened up the possibility of dating the middlewest-ll middlewest-ll cultures.
