e speaker's chief
resources on the platform--it is the greatest of all teaching gifts. It
is a gift, moreover, that responds to cultivation. Read the three
extracts from Arlo Bates as their author delivered them, as one passage,
and see how they melt into one, each part supplementing the other most
helpfully.

=Analogy=, which calls attention to similar relationships in objects not
otherwise similar, is one of the most useful methods of exposition. The
following striking specimen is from Beecher's Liverpool speech:

A savage is a man of one story, and that one story a cellar.
When a man begins to be civilized he raises another story. When
you christianize and civilize the man, you put story upon story,
for you develop faculty after faculty; and you have to supply
every story with your productions.

=Discarding= is a less common form of platform explanation. It consists
in clearing away associated ideas so that the attention may be centered
on the main thought to be discussed. Really, it is a negative factor in
exposition though a most important one, for it is fundamental to the
consideration of an intricately related matter that subordinate and side
questions should be set aside in order to bring out the main issue. Here
is an example of the method:

I cannot allow myself to be led aside from the only issue before
this jury. It is not pertinent to consider that this prisoner is
the husband of a heartbroken woman and that his babes will go
through the world under the shadow of the law's extremest
penalty worked upon their father. We must forget the venerable
father and the mother whom Heaven in pity took before she
learned of her son's disgrace. What have these matters of heart,
what have the blenched faces of his friends, what have the
prisoner's long and honorable career to say before this bar when
you are sworn to weigh only the direct evidence before you? The
one and only question for you to decide on the evidence is
whether this man did with revengeful intent commit the murder
that every impartial witness has solemnly laid at his door.

=Classification= assigns a subject to its class. By an allowable extension
of the definition it may be said to assign it also to its order, genus,
and species. Classification is useful in public speech in narrowing the
issue to a desired phase. It is equally valuable for showing a thing in
its relation to o
