In some respects the work of the 1913-14 Conference was admittedly incomplete, and in other directions subsequent study and experience! showed that some amendment of the provisions of the Convention was necessary.

So far as wireless is concerned these regulations will deal with cer- tificates and the duties of operators and watchers, and will give effect generally to the wireless provisions of the Parliamentary measure.

Ships other than passenger ships will carry wireless telegraphy certifientes or (if exempted) exemption qurti- Sientes. The certificates will.
