co-operation with other institutions 



It has always been the desire and the practice of this Museum to lend 

 full co-operation to other institutions and individuals engaged in the 

 studies within our field. As the dissemination of knowledge is one of 

 our prime objectives, we are eager also to assist in the training of 

 those who will further this objective in the years to come. From this 

 point of view, the following summary of co-operative activities indi- 

 cates substantial progress toward the accomplishment of our collec- 

 tive mission.

 Ethnology, and Roland W. Force, Curator of Oceanic Archaeology 

 and Ethnology, gave lectures on South America and Oceania, respec- 

 tively, in a series of lectures called "Places and Peoples" sponsored 

 by the University of Chicago and held at the Museum. On the day 

 following each lecture, members of the audience were taken by the 

 lecturers on a tour of pertinent exhibits. George I. Quimby, Curator 

 of North American Archaeology and Ethnology, conducted a seminar 

 at the University of Chicago on rates of culture change in eastern
