                  Traffic Statistics (September 1973)

   Attached are the Host traffic statistics for the month of
   September 1973.  It is my intention to issue Traffic Statistics
   for October, November, and December in RFC form, and then to
   remove these reports from the RFC series.  I will continue to
   produce the reports, and so could have the NIC distribute them
   to technical Liaisons if there is any interest.  Alternatively,
   I could continue issuing them as RFC's if there is great interest.
   Let me know.

   Attach.
