Sadly, the majority of artifacts are not stamped with their date of manufacture.
This dating technique only applies to pipe stems manufactured in England between approximately 15.
Pipe stem dating You have recovered sixty-three pipe stem fragments from Verysignificantsite. Harrington's initial studies, the time periods and average bore diameters are as follows (Deetz 19): Look at the number of stems you recovered and determine which bore diameter is represented by the most pipe stems.
You wish to analyze these pipe stems to determine when your site was most heavily occupied. Match the most frequently occurring diameter with Harrington's bore diameter chart above.
The University of Michigan's architectural engineering program required students to complete an internship or architecture-related research project.
To meet this requirement, Harrington spent the summer of 1923 with the School for American Research in Santa Fe, New Mexico, creating measured plan drawings of Spanish mission churches.
