By 1800 this diameter had decreased to 4/64 of an inch.
This change in diameter may have occurred because pipe stems became longer through time, requiring a smaller bore.
About ten years later in 1962 Lewis Binford expanded on Harrington’s histogram and applied a linear regression formula to the relative percentages.
The Binford regression formula, Y=1931.85-38.26X, is a fairly simple idea.
This formula is used by all colonial archaeologists to help date their sites.
There are currently two other formula methods; Hanson’s ten linear formulas and the Heighton and Deagan curvilinear formula.
Basically, it all started in Colonial Williamsburg in the 1950s, as most things in historical archaeology do. From Harrington 1954: “Dating Stem Fragments of Seventeenth and Eighteenth Century Clay Tobacco Pipes.” Quarterly Bulletin of the Archeological Society of Virginia 9(1):10-14.They invested in the warehouse and put in a secret passage to their buried treasure in the cellar.I hope we find it soon; my student loans are stacking up…Adventures in the Field: Archaeology at Historic Bath, NC is a series of posts about Lauren’s experiences as a TA at East Carolina University’s summer 2009 archaeology field school in Bath, NC. Week four was defined not by new archaeological discoveries on the site, but by new methodological and interpretive breakthroughs.We got down almost to the bottom of the stairs this week, which is very exciting.
Now that we have a large portion of the cellar wall exposed, it appears that the foundation of the building was in Flemish bond; and as all you good preservationists know, that’s the fanciest bond.
