Editing Private Express Statutes (section)

===Occasional private mail delivery===
One does not need to establish a private mail delivery service for the occasional commercial transport of a letter outside the mails so long as the rate which would have been due to the USPS is affixed in stamps, the stamps are cancelled in ink, and the date of receipt by the carrier or the transport of the letter, are noted thereon.  All these privately carried letters can bear a [[private cancellation]] if the cancellation is done in ink; private cancellations are different from [[private overprint]]s on postage stamps.
