He then attended the Massachusetts Institute of Technology (MIT) in Boston, where he took courses in the architectural school for a year.Harrington completed his bachelor's degree in architectural engineering at the University of Michigan in 1924.The longer stems were attended by narrower holes through which smoke was drawn from the bowl, and therein lies useful information. In 1961, Lewis Binford used Harrington’s data to calculate a simple linear regression model to assign an occupation date to archaeological sites using the recovered pipe stems.While only approximate to within twenty years, the dates are easily determined in the field, whereas dates derived from pottery or wood samples require far more analysis and expertise.When we study a site, we also study the documents associated with the site.For Historical archeologists, ceramics are a diagnostic tool for dating because many English ceramic types can be dated to within 5 or so years of their manufacture.Archaeologists digging at sites within the former British colonies find large numbers of broken pipe stems, which often represent the third most common artifact after pottery sherds and siding nails.Initially imported from England, clay pipes were slowly refined during the 17th and 18th centuries from rather stubby smoking implements measuring about 3” in length to slender and stylish foot-long affairs. Harrington published a statistical summary of pipe stem hole diameters and their corresponding date of manufacture.

He would be known to his friends and colleagues as "Pinky" from graduate school onward. His mother who was named Patricia and father named Edwards were both teachers, though his father later became a school superintendent.This led Harrington's family to relocate to a series of small Michigan towns, including Scottville, Ypsilanti, Vasser, and Albion, during his youth.Named "Most Likely to Keep Busy" by his high school annual, Harrington, following his graduation, completed a two-year pre-engineering program at Albion College while working a series of jobs.Historical archeologists do not rely on pipe stem fragments as the only source for determining a site's history.They also consider historical documents and other material culture recovered from the site—such as ceramics, glass, metal artifacts, faunal and botanical samples, and features—to determine its occupation and use.
