The Association, which is an incorporated nonprofit sharing Organization, has several objectives, of which probably the most important is to publish, and make available to the public, accurate and interesting scientific and popular material. Others of its goals include the fostering in the Southwestern National Monuments the development of libraries, museum and trailside exhibits, the encouragement of research, etc.

The eight booklets of the Popular Series (which are listed on the back cover of this report) have appeared with some frequency, and have enjoyed immediate acceptance as valuable information concerning the Southwestern scene. The only Technical Series publication to appear, however, was Prehistory of El Rito de los Frijoles, Bandelier National Monument, by J. W. Hendron in 1940, now long out of print.

It is hoped that the logjam of unpublished scientific papers, of which this is the first to emerge, can be broken to make this valuable material available for use by scientists, and to form the solid foundation for a well-built interpretive structure in the Southwestern National Monuments.

Herein is announced a change in nomenclature: the above-mentioned Technical Series No. 1 will henceforth be considered as Volume 1, and archeological and historical volumes will be numbered with odd numbers. Natural history ones will receive the even numbers. Thus an individual or library interested in only one of the subjects need be concerned with only one of the number series. Most volumes will be complete in one cover, but in order not to delay the issuance of minor papers on the multiplicity of activities which center in the widely-varied Southwestern National Monuments, an occasional volume will be made up of shorter articles, each printed promptly upon completion, and issued unbound, but with successively numbered pages. When these parts add up to a hundred pages or so, a final paper will close the volume and include an index.

To sum up: those requesting notification of publications of historical and archeological papers should specify odd-numbered volumes; conversely, for natural history, even-numbered ones. Volumes containing miscellaneous shorter papers, in both series, will be closed, when of a convenient size, by the issuance of a volume index.
