wind powered ship

I was foolish yesterday to even suggest that those mail boats were responsible for long delays in mail delivery. It's obvious by the length of delays that no self propelled vessel could possibly travel that slow. Mail service obviously uses ships powered by wind and sail to mail my letters. Either that or they get a few men to ROW in an old Galleon which is under manned.
Time sure heals wounds. These stamps and this cover honor the establishment and independence of America. It wasn't such a noble thing in GB's eyes a couple hundred years ago.
I'll bet those ships landing on Long Island were carrying letters. Probably about as fast as the mail boats in yesterdays column.
Why is the Battle of Jersey depicted on a Jersey and Massachusetts stamp commemorating the US bicentennial? The battle was in 1881 5 years AFTER the US declared independance. Weak stamp, very weak. Granted an artist from Mass drew it, but there is no evidence that he was ever really IN Jersey. Ever!!!
