	abstract = {<p>A number of centres or areas characterized by ground slate industries are examined for possible derivation from a few original centres. It is found that where relationships might be expected on the basis of proximity or age there often are disjunctures in time, space or techniques that fail to support derived origins. It is concluded that regional innovation has led to the development of several essentially independent ground slate industries. Presently no direct links are seen between West Coast, south Alaskan, Bering Strait, Asian Maritime Territory, early Dorset, and Northeastern U.S./Atlantic Provinces distributions though in a few instances stimulus may be suspected.</p>},
