Public notices how to be given.

Any public notice required to be given under any of the provisions of this Act shall be in writing under the signature of a competent authority and shall be published in the locality to be affected thereby, by affixing copies thereof in conspicuous public places, or by proclaiming the same through public announcement, or by advertising in local newspapers as the said authority may deem fit. Provided that the competent authority may, on being satisfied that it is in public interest to bring any regulation into force with immediate effect, make such direction or regulation without previous publication.
