A CONFERENCE on tree ring studies was held on June 11-12, at the Museum of Northern Arizona at Flagstaff, under the chairmanship of Dr. A. E. Douglass of the University of Arizona. Among the problems discussed was the need for a journal in which to publish the original data on which climatological conclusions and prehistoric dates are based. It was, therefore, decided to publish a quarterly journal to be called the Tree Ring Bulletin, at a subscription price of 1.50 dollars a year. Dr. A. E. Douglass will be editor-in-chief; Dr. Waldo S. Glock, assistant editor; Dr. Harold S: Colton, managing editor; and Mr. John C. McGregor, assistant managing editor. While the publication will be of immediate interest to archaeologists, it will also deal with problems of climatology and other subjects to which tree ring studies are related. Further information can be obtained from Dr. Harold S. Colton, Museum of Northern Arizona, Flagstaff, Arizona.
