ABSTRACT
In 1954 J. C Harrington published an article on the study of metrical changes in kaolin pipe stem hole diameters through time. He found that there was a general and regular reduction in the hole diameters as from 1620 to 1800. In the way of explanation it is quite obvious that with the influx of pipes manufactured in Montreal and at other seats of American pipe making there is a corresponding reoccurrence of certain “early” styles, in addition to the appearance of a new style of elements. The factors taken together resulted in there being many more pipes in use during the late period as contrasted with the early period. Thus, the increased rates of accumulation for the late period tend to skew the total sample from the site in favor of a later date.
