y be set
off as a separate paragraph in order to secure greater emphasis.
This, however, is only using the paragraph for a proper purpose--to
aid in gaining clearness.

144. PARAGRAPHING OF SPEECH. In a narrative, each direct quotation,
together with the rest of the sentence of which it is a part, should
constitute a separate paragraph. This rule should be always followed
in writing a conversation. Examine the following:

A certain Scotch family cherishes this anecdote of a trip which
Dr. Samuel Johnson made to Scotland. He had stopped at the house
of this family for a meal, and was helped to the national dish.
During the meal the hostess asked:

"Dr. Johnson, what do you think of our Scotch broth?"

"Madam," was the answer, "in my opinion it is fit only for pigs."

"Then have some more," said the woman.

The only case in which the quoted words can be detached from the
remainder of the sentence is where they form the end of the sentence
after some introductory words, as in the second paragraph of the
example just given.

145. INDENTATION OF THE PARAGRAPH. The first sentence of each new
paragraph should be indented. See example under Sec.144. No other
sentence should be so indented.

146. The essential qualities which each paragraph should have are:
Unity, Coherence, and Emphasis.

UNITY. Unity requires that the paragraph should deal with only one
subject, and should include nothing which does not have a direct
bearing on that subject. Thus, in the following paragraph, the
italicized sentence violates the principle of Unity, because, very
obviously it belongs to some other paragraph:

Never did any race receive the Gospel with more ardent enthusiasm
than the Irish. _St. Patrick, a zealous priest, was thought to
have banished the snakes from the island_. So enthusiastic were
the Irish, that, not content with the religious work in Ireland,
the Irish Church sent out its missionaries to Scotland, to Germany,
and to the Alps and Apennines. It founded religious houses and
monasteries....

Separate paragraphs should not be made of matter which belongs
together. If the ideas can all be fairly included under one general
topic, unity demands that they be grouped in one paragraph. Thus,
in describing the route followed in a certain journey, one should
not use a separate paragraph for each step in the journey.
