I read in today’s papers that a megaphone amplifying the telephone and carrying the voice to a crowd has been tested (and has given fine results) in Kazan.
Check through Ostryakov. If this is true we must have it installed in Moscow and Petrograd, and incidentally, check up on all their work.
Let them give me a short written report:
1) calendar programme of their work;
2) ditto—a speaking telephone exchange for 2,000 versts in Moscow.
When will it be ready?
3) Ditto—receivers. How many being made?
