"Black Chambers" to Steal Secret Messages Shanghai's ' telegraph and radio offices have worked overtime recently to handle the rush of messages to and from Europe and America which have resulted from the Europen war, the "Tairiku Shimpo" reported yesterday.
At the Shanghai International Radio office the number of messages between this city and Rome and Berlin, only two points in Europe with which service is maintained, has increased by 600 per cent. in the last few weeks, the paper said. The daily average of Messages sent to Rome is now about 40 while 30 go to Berlin.
The Great Northern Telegraph Ca., the Eastern Extension Telegraph Ca. and the Commercial Pacific Cable Ca. are also reported to be busy.
Over 230 messages between here and American cities are handled by the R.C.A. Communications Ca. and the Mackay Radio and Telegraph Ca., the paper reported, of which almost two thirds are outgoing cables.
The "Tairiku" observed that lack of official control over radio communication in Shanghai has given rise to international radio warfare here as diplomatic and military authorities of foreign nations operate their own radio services.
An official of the Shanghai Inter-rational Radio office told a reporter from the paper that important diplomatic messages seldom pass through the ordinary commercial channels.
He added that authorities of various nations have established "Black chambers" here "to steal the secret mes-seges," the paper said.
