Sec.  1.358   Tariffs as evidence.

   In case any matter contained in a tariff schedule on file with the
   Commission is offered in evidence, such tariff schedule need not be produced
   or marked for identification, but the matter so offered shall be specified
   with particularity (tariff and page number) in such manner as to be readily
   identified, and may be received in evidence by reference subject to check
   with the original tariff schedules on file.
