Glenn Drummond sent this interesting Hemingray Glass Company ad from Gould's 1873 St. Louis Business Directory. Research has not verified that a Hemingray factory was located in St. Louis. More likely than not, it was only a warehouse and office.                                                                                        
                                                                     

Dick Roller, author of Indiana Glass Factory Notes, provided the following two advertisements for Bushwick Glass Works and S. McKee & Company.

It is interesting to note that William Brookfield still referred to Bushwick Glass Works in his ad that ran in China, Glass and Lamp, August 9, 1893.

The Pittsburgh Morning Post contained this ad in its August 25, 1855 edition. A similar ad was also appeared in the August 4, 1857 paper. Neither ad has been published before. It would be interesting to know what insulators and lightning rod insulators were being produced by McKee in 1855.
