A RULE FOR PEACE.--If it be possible, as much as lieth in you, live
peaceably with all men.--_St. Paul._

The dash is sometimes used in catalogue work as a ditto mark.

French printers use the dash in printing dialogue as a partial
substitute for quotation marks. Quotation marks are placed at the
beginning and end of the dialogue and a dash precedes each speech. This
form is used even if the dialogue is extended over many pages.

_Rules for the Use of the Dash_

1. To mark abrupt changes in sentiment and in construction.

Have you ever heard--but how should you hear?

2. To mark pauses and repetitions used for dramatic or rhetorical
effect.

They make a desert, and call it--peace.
Thou, great Anna, whom three states obey,
Who sometimes counsel takes--and sometimes tea.

3. To express in one sentence great contrariety of action or emotion or
to increase the speed of the discourse by a succession of snappy
phrases.

She starts--she moves--she seems to feel
The thrill of life along her keel.

In this connection DeVinne gives the following excellent example from
Sterne:

Nature instantly ebbed again;--the film returned to its place;--the
pulse fluttered,--stopped,--went on,--throbbed,--stopped
again,--moved,--stopped,--Shall I go on?--No.

Attention may be called to Sterne's use of the semicolon and the comma
with the dash, a use now obsolete except in rare cases.

4. To separate the repetition or different amplifications of the same
statement.

The infinite importance of what he has to do--the goading conviction
that it must be done--the dreadful combination in his mind of both
the necessity and the incapacity--the despair of crowding the
concerns of an age into a moment--the impossibility of beginning a
repentance which should have been completed--of setting about a
peace which should have been concluded--of suing for a pardon which
should have been obtained--all these complicated concerns
intolerably augment the sufferings of the victims.

5. At the end of a series of phrases which depend upon a concluding
clause.
