for example, acting under authority given to it by Congress, that
provides the people with their system of money and with a banking
system, both of which are great cooperative devices. The
Department of Commerce serves the farmer directly by discovering
markets for his products in every part of the world, and

commerce. The rural mail delivery, the parcel post, and the motor
