The Dancing School in Carter's Alley, is opened by the
subscriber.  He thinks it unnecessary to say any thing of
his abilities, having taught these ten years past in this
city, makes no doubt that his reputation both as a citizen
and teacher in his branch is well known.
The Evening School will begin as soon as a sufficient number
of young gentlemen offer.
