tion is whether it takes broadcasting beyond the legislative power.
In dealing with such a question it must not be forgotten that it is a
constitutional power intended to provide for the future and bearing
upon its face an attempt to cover unknown and unforseen develop-
ments. A wide operation should be given to such a power. In
the next place the description " telegraphic and telephonic " carries
with it, not by derivation, but by use, a reference to electrical means
of transmission of signals and speech. Broadcasting, whether
conducted by private enterprise or by a governmental body, is a
public service and it is telephonic in its nature. In the case of

their Lordships, said that they were of opinion that it was and fell
"within both the word ' telegraphs' and the general words ' under-

fairly within the expression " services." He returned to the state-
ment that their Lordships thought broadcasting fell within the
description of telegraphs and said : - *' No doubt in everyday speech
telegraph is almost exclusively used to denote the electrical instru-
ment which by means of a wire connecting that instrument with
