1887, as
interpreted in the Shreveport Case, was greatly enlarged by Sec. 416 of
the act of 1920, which authorizes the Commission to remove "any undue,
unreasonable, or unjust discrimination against interstate or foreign
commerce." Thus, commerce as a whole, instead of specific firms or
localities, is made the beneficiary of the restriction. In the Wisconsin
R.R. Comm. _v._ Chicago, B. & Q.R.R. Co.,[386] the Court held that this
section sustained the Interstate Commerce Commission in annulling
intrastate passenger rates which it found to be unduly low, in
comparison with rates which the Commission had established for
interstate travel, and so tending to thwart, in deference to a merely
local interest, the general purpose of the act to maintain an efficient
transport service for the benefit of the country at large.[387]

REGULATION OF OTHER AGENTS OF CARRIAGE AND COMMUNICATION

In the Pipe Line Cases, decided in 1914,[388] the Court affirmed the
power of Congress to regulate the transportation of oil and gas in pipe
lines from one State to another and held that this power applies to such
transportation even though the oil (or gas) in question was the property
of the owner of the lines.[389] Thirteen years later, in 1927, the Court
ruled that an order by a State commission fixing rates on electric
current generated within the State and sold to a distributor in another
State was invalid as imposing a burden on interstate commerce, thus
holding impliedly that Congress' power to regulate the transmission of
electric current from one State to another carried with it the power to
regulate the price of such electricity.[390] Proceeding on this
implication Congress, in the Federal Power Act of 1935,[391] conferred
upon the Federal Power Commission the power to govern the wholesale
distribution of electricity in interstate commerce; and three years
later vested in the same body like power over natural gas moving in
interstate commerce.[392] In Federal Power Commission _v._ Natural Gas
Pipeline Company,[393] the power of the Commission to set the prices at
which gas, originating in one State and transported into another,
should be sold to distributors wholesale in the latter State, was
sustained by the Court in the following terms: "The argument that the
provisions of the statute applied in this case are unconstitutional on
their face is without merit. The sale of natural gas originating in the
State and its transportation and
