I will be starting excavation at a warehouse in Georgetown,
     Washington, D.C. which was built ca. 1785 as a tobacco warehouse and
     in use through the nineteenth and into the twentieth century.  When
     tobacco declined, the warehouses were fitted for commercial and
     industrial purposes.  I am looking for comparative information.
 
     Thanks.
