COLUMBIAN CENTINEL, Boston, Sept. 14, 1796  

* USS United States construction

Page 2 has a report noting: "The United States frigate, building in Southwark under the direction of Mr. Humphreys,  is in such a state of forwardness that it is probable she might be launched before the ensuing winter, should occasion require (We wish we could say as much of the Boston frigate)."
This was the frigate 'United States", which was being built in Philadelphia. It was one of the first 3 frigates built for the fledgling U.S. Navy. The "Boston frigate" reference is to the 'Constitution', being built in that city.
Four pages, various foxing, some flaking at the right margin does not affect the mentioned content.
