The goal of my thesis is to determine which of these methods, if any, are the most accurate and reliable.Also, we have been informed that there are steps similar to ours in the Palmer-Marsh House, a 1750s house located on the other side of town.The stairs leading down into the basement kitchen of the house have wide brick steps with short wooden risers, whereas, ours would have had a short brick part and a long wooden step.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.I’ll give you a brief history and idea of how pipe stem dating works. Harrington noted that imported English white clay tobacco pipe stem fragments change over time in a measurable manner, following the basic trend of decreasing bore (the hole where one would suck smoke through) diameter from the 17Harrington’s pipe stem periods.

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.

The clay pipe industry expanded rapidly as tobacco smoking gained popularity in both England and America. Harrington studied the thousands of pipe stems excavated at Jamestown and other colonial Virginia sites, noticing a definite relationship between the diameter of the pipe stem bore—or hole—and the age of the pipe of which it had been part.

Historical archeologists excavating English colonial sites often find pieces of white clay smoking pipes on their sites. The earliest pipes, dating to about 1600, had stems with 9/64-inch diameter bores.

Robert, a field school and graduate student, is doing his thesis on geospatial technologies and their usefulness to archaeology.

One of the sites that he is using is the Palmer-Marsh cemetery, and he was out there most of the week setting up a grid and making a map, getting ready for his data collecting.

In fact, Dawn, the other TA, is comparing our cellar to South’s in an effort to determine socio-economic status of the citizens of Bath.
