The Colon is used to divide a sentence into two or more parts
less connected than those which are separated by a semicolon;
but not so independent as separate, distinct sentences.
RULE 1. When a member of a sentence is complete in itself, but followed
by some supplemental remark, or farther illustration of the subject, the
colon may be properly employed; as, "Nature felt her inability to
extricate herself from the consequences of guilt: the gospel revealed
the plan of divine interposition and aid." "Great works are performed,
not by strength, but by perseverance: yonder palace was raised by single
stones; yet you see its height and spaciousness."
_Exercises._--The three great enemies to tranquillity are vice
superstition and idleness vice which poisons and disturbs the mind with
bad passions superstition which fills it with imaginary terrors idleness
which loads it with tediousness and disgust.
When we look forward into the year which is beginning what do we behold
there? All my brethren is a blank to our view a dark unknown presents
itself.
RULE 2. When a semicolon has preceded, or more than one, and a still
greater pause is necessary, in order to mark the connecting or
concluding sentiment, the colon should be applied; as, "A divine
legislator, uttering his voice from heaven; an almighty governor,
stretching forth his arm to punish or reward; informing us of perpetual
rest prepared for the righteous hereafter, and of indignation and wrath
awaiting the wicked: these are the considerations which overawe the
world, which support integrity, and check guilt."
