Also indicated by their study was the fact that confusion exists 

 among anthropologists as to what constitutes a "true loom." The 

 only possible archaeological evidence of a true loom would be the 

 finding of a heddle or some other mechanical device which would 

 lift a number of warp threads at one time, for without proof of 

 a mechanically produced shed, there is no tangible evidence of a 

 true loom. 



As a result of their study, Messrs. Martin, Collier and Quimby 

 believe it is impossible to tell whether a given Indian textile was 

 woven on a loom, because some identical weaves can be produced 

 either by looms or by any one of several finger techniques. 



Additional research projects conducted by Mr. Quimby were as 

 follows: A synthesis of Aleut archaeology and ethnology, prepared 

 for possible publication as an Anthropology Leaflet; a comparative 

 study of some Hopewell and northern Algonkian art motifs which 

 led to the hypothesis that the designs were similar in form and con- 

 struction and that the Hopewell Indians and the ancestors of the 

 northern Algonkians were culturally connected (the results of this 

 study were published in the American Anthropologist). 



A study of Hopewellian tools and ornaments from Michigan and 

 Indiana was published by the Michigan Academy of Science. The 

 research was based upon collections in the Chicago Natural History 

 Museum. 



Curator Collier carried out research on Inca civilization during 

 the fifteenth century a.d. in order to plan and supervise a Peruvian 

 diorama which was under construction during the year. It was 

 necessary to study Inca costumes, economy, and architecture, and 

 to collect information on the vegetation and general environment of 

 the Urubamba Valley in southern Peru, the setting for the diorama. 

 Through the courtesy of Mr. Rene d'Harnoncourt it was possible 

 to secure especially taken color photographs of the region, and 

 these slides have been of tremendous assistance. 



During the year the Museum Press issued Mr. Collier's report, 

 prepared in collaboration with Mr. John V. Murra, entitled Survey 

 and Excavations in Southern Ecuador. This publication sets forth 

 the scientific results of the 1941 Field Museum-Andean Institute 

 Archaeological Expedition to Ecuador, a detailed account of which 

 was given in the Annual Report for 1942. 



Mr. Collier has been appointed Editor of South American Archae- 

 ology for The Handbook of Latin American Studies, an annual publi- 

 cation which lists and reviews scholarly publications.
