there is any ambiguity) between an infinitive that
_expresses a purpose_, and an infinitive that does not, _e.g._ "He
told his servant to call upon his friend, _to_ (in order to) give him
information about the trains, and not to leave him till he started."

*30. The principle of suspense.* Write your sentence in such a way
that, until he has come to the full stop, the reader may feel the
sentence to be incomplete. In other words, keep your reader in
_suspense_. _Suspense_ is caused (1) by placing the "if-clause" first,
and not last, in a conditional sentence; (2) by placing participles
before the words they qualify; (3) by using suspensive conjunctions,
_e.g._ _not only_, _either_, _partly_, _on the one hand_, _in the
first place_, &c.

The following is an example of an _unsuspended_ sentence. The sense
_draggles_, and it is difficult to keep up one's attention.

"Mr. Pym was looked upon as the man of greatest experience in
parliaments, | where he had served very long, | and was always a man
of business, | being an officer in the Exchequer, | and of a good
reputation generally, | though known to be inclined to the Puritan
party; yet not of those furious resolutions (_Mod. Eng._ so furiously
resolved) against the Church as the other leading men were, | and
wholly devoted to the Earl of Bedford,--who had nothing of that
spirit."

The foregoing sentence might have ended at any one of the eight points
marked above. When suspended it becomes:--

"Mr. Pym, owing to his long service in Parliament in the Exchequer,
was esteemed above all others for his Parliamentary experience and for
his knowledge of business. He had also a good reputation generally;
for, though openly favouring the Puritan party, he was closely devoted
to the Earl of Bedford, and, like the Earl, had none of the fanatical
spirit manifested against the Church by the other leading men."

*30 a. It is a violation of the principle of Suspense to introduce
unexpectedly, at the end of a long sentence, some short and unemphatic
clause beginning with (a) " ... not" or (b) " ... which."*

(_a_) "This reform has already been highly beneficial to all classes
of our countrymen, and will, I am persuaded, encourage among us
industry, self-dependence, and frugality, _and not, as some say,
wastefulness_."

Write "not, as some say, wastefulness, but industry, self-dependence,
and frugality."

(_b_) "After a long and tedious journey, the last part of which was a
l
