While tracking down info about a northern do-good philantrophic gent of
the 19th century who sent funds down heah to help establish black
churches after the war,  I happened upon a series of articles published
in the 1890s in Manufacturer and Builder titled the Decay of Building
Stones of the City of New York and Vicinity.  At first glance it looks
like it would be most interesting to all y'all NYC stone guys.  Names
buildings, quarries, good building stone and bad, etc.  Manufacturer and
Builder is in the Cornell Making of America digital libtrary and if all
goes well, the following link will go to the portion of the index with
the decay articles.
