TELECOMMUNICATIONS

Notification of Transmission.

The sender of a radiotelegram may be advised by telegraph of the date and time at which his message is transmitted to the ship. The indicator PC must be prefixed to the address, and there is an additional charge of 25 cents.

Repetition at Request of Sender.

If the sender so desires a radiotelegram may be repeated from office to office throughout its trans- mission.

An additional charge of one half the cost of the radiotelegram is made for the service. In each case the indicator TC should precede the address of destination.

Cancellation.

A radiotelegram may be cancelled by the sender after it has been accepted for transmission.

If the message has been transmitted to the ship of destination, cancellation may be effected by an official radiotelegram to the ship of destination. The or- dinary rates are charged but the address of the radiotelegram is not charged for. In addition there. is a charge as for six words at the ordinary rate for the reply, if the sender wishes to be informed that his request has been complied with.

If the cancellation radiotelegram does not overtake the original, the addressee is advised of the cancella- tion unless instructions to the

the contrary have been given.

Non-Delivery.

When for any reason a radiotelegram to a ship at sea cannot be delivered, the sender is advised of non-delivery.

When a ship does not communicate with the coast station and it has not been possible to dispose of a radiotelegram by the morning cf the fourth day follow- ing the day of handing in, the sender is advised that the message has not been transmitted; but the radiotelegram is retained at the coast station until the end of the seventh day in case the ship communicates. If it is learned that the ship has docked or has definitely passed out of wireless range, and there is no prospect of transmitting the radiotelegram, the sender is advised at once.
