Sir: The best way would be for all mail to be stamped second class. The Post Office could not possibly allow a build-up of delayed mail if this was done. When the iniquitous two-tier system was introduced I resisted it for some in the end succumbed. I shall in future stamp all my letters second class, including this one.
