successful, we have learned by experience where it is best to

"'Magnetic eyes' are of great use to miners and Civil engineers.
These instruments are something like the mariner's compass, with
the sensitiveness enormously increased by galvanic currents. The
'eye,' as it were, sees what substances are underground, and at
what distances. It also shows how many people are in an
adjoining room--through the magnetic properties of the iron in
their blood--whether they are moving, and in what directions and
at what speed they go. In connection with the phonograph and
concealed by draperies, it is useful to detectives, who, through
a registering attachment, can obtain a record of everything said

"Our political system remains with but little change. Each State
has still two United States Senators, though the population
represented by each representative has been greatly increased, so
that the Senate has grown numerically much more than the House.
It is the duty of each member of Congress to understand the
conditions existing in every other member's State or district,
and the country's interest always precedes that of party. We
have a comprehensive examination system in the civil service, and
every officeholder, except members of the Cabinet, retains his
office while efficiently performing his duty, without regard to
politics. The President can also be re-elected any number of
times. The Cabinet members, as formerly, usually remain in
office while he does, and appear regularly in Congress to defend
their measures.
