anything which, in the exercise by itself of a fair discretion, may
be deemed appropriate to save the act of inter-State commerce
from prevention or interruption, or to make that act more secure,
more reliable or more efficient." The argument adopted by the
Court, as I condense it, went on to point out that the men and
the things used in the act or operation of inter-State commerce
were the agents or instruments of that commerce, and that their
destruction during the act would stop, or their interruption would
interrupt, that commerce. If they were not of the right
kind or quality, inefficiency of some kind would ensue; and
wrong or disadvantageous conditions of working would prevent
or interrupt the act of commerce, or diminish its expedition,
reliability, economy, or security. "Therefore," it was said (1),
"Congress may legislate about the agents and instruments of
inter-State commerce, and about the conditions under which
those agents and instruments perform the work of inter-State
commerce, whenever such legislation bears, or in the exercise of
a'fair legislative discretion can be deemed to bear, upon the
reliability or promptness or economy or security or utility of
the inter-State commerce act." The judgment must, of course,
be read in relation to the character of the legislation discussed.
The Statute there in question was on its face designed to secure
greater care on the part of the common carriers and thereby
greater safety to the employees in the operations of inter-State
trade, and by such regulation of conduct to secure the safer,
prompter, and more certain carriage of travellers and goods; and
the ambit of the power was, of course, held to cover any such
legislation. Had it been the intention of the Statute, in the
endeavours of Congress to consult the public welfare, to impose
restrictions on inter-State or foreign commerce to any extent
which the: legislature thought right in the circumstances, the
same principles would have been applied. It is as well to quote
two of the propositions of the Court bearing upon "the extent
and nature of this power,' which were considered "no longer
open to dispute." 'They are as follows (2): - (3) "'To regulate,'
in the sense intended " (and regulation is included in the term " to
make laws"), "is to foster, protect, control and restrain, with
