(a) Main House Felling Date: Summer 1746


Brace (1/1) 1745 (C). Individual sample 1678-1745 (oak) bosw1 (t =7.28 MTVx3; 6.63 VA2011; 6.39 PIEDMO).


Bostwick Hall is being used as a study building for students taking the HISP 655 American Vernacular Architecture and Documentation course as part of the Graduate Program in Historic Preservation at the University of Maryland’s School of Architecture, Planning and Preservation. To allow as many students as possible to see the entire dendrochronological process being undertaken, it is planned to take one sample each time the course is offered. As more samples are taken, this interim report will be updated to show any new findings. A final report will be produced once six to ten samples have been collected, the normal amount required for a complete dendrochronological study.

Please contact Michael Worthington at michael@dendrochronology.com to make sure you are using the most up-to-date interim report.
