A carrier of messages by telegraph must, if it is practicable, transmit every such message immediately upon its receipt. But if this is not practicable, and several messages accumulate upon his hands, he must transmit them in the following order:
1. Messages from public agents of the United States or of this State, on public business;
2. Messages intended in good faith for immediate publication in newspapers, and not for any secret use;
3. Messages giving information relating to the sickness or death of any person;
4. Other messages in the order in which they were received.
(Enacted 1872.)
