knows how to apply the right stimulus at the
right time in order to arouse the desired interest.

In many ways the adult is but the child of a larger growth, who needs
something concrete to make him understand. And so have grown up the
great industrial fairs and exhibitions. One comes away from these
wondering that so much, both good and bad, is being prepared for him,
and stimulated, usually, to work out certain suggestions and better
many of the present conditions. Both the manufacturer and the consumer
have been helped.

Wherever it is possible, a working model illustrating the chief
features to be explained should be installed. The expense of this kind
of exhibit has in the past been prohibitive, and moreover the use of
such "claptrap" has been frowned upon; but scientific knowledge is no
longer to be held within the aristocratic circle of the university. It
is to be brought within the reach of the man in the street, and to
make up for the wasted years of seclusion experts now vie with each
other in putting cause and effect not merely into words but into
pictures, and even into motion pictures. The fly as a carrier of
disease is now shown in all its busy and disgusting activity. The
lesson of awakened attention by such means is being learned, and soon
lessons in botany, in gardening, in housewifery, will be given through
the eye, to be the better followed by the hand.

Of all means, that product of man's ingenuity, the moving picture, is
destined to play the greatest part in quick education. It is the
quintessence of democracy.

The extension movement in education is an evidence of a new social
ideal. It is a true expression of democracy that the university and
school can be utilized by the busy working people. Museums that at one
time were only for the educated who by previous training could
understand them now assume as a privilege the educating of all the
people. Schools of art and science, also, through lectures, bulletins,
guides, and special exhibits, extend a generous welcome to the public.

The citizens ought to be a gladder, sadder people, stirred and
delighted and grateful for much that the city affords; sad and shocked
by some of the forbidding, existing conditions. That is the power of
an exhibit, so to visualize a condition that the mind really
conceives it, never again to recover from the shock, to be unmindful
of such possibilities of degraded existence for human beings.
