Chronology of the Tano Ruins, New Mexico

In the course of archeological investigations pursued in New Mexico under the auspices of the American Museum during the past four years some chronological data have come to light which it seems proper to bring to the attention of students without further delay. The data consist mainly of observations on the strati-graphic relationship of several widely distributed types of pottery. Other facts of importance, such as architectural variation, exist, but these are less convincing and besides seldom immediately useful in determining the relative age of a ruin. This preliminary treatment is therefore deliberately confined to a presentation of the stratigraphy, together with a brief outline of the distinguishable ceramic features and the application of the results thus obtained to the ruins in the limited area under investigation.
