IX The terminations _-ing_, _-en_, _-ed_, _-er_, _-est_, and the plural _-es_ go over to the next line except when the preceding consonant is doubled, or when they follow _c_ or _g_ soft.
_lead-ing_ _beat-en_ _larg-er_, but _lat-ter_ _for-cing_ _ran-ging_
X Do not end a line with _j_ or with _c_ or _g_ soft.
_pro-cess_ _ne-cessary_ _pre-judice_ _prog-eny_
XI Adjectives in _ical_ divide on the _i_.
XII In derivatives of words ending in _-t_, the division follows the accent.
_objec-tion_, not _object-ion_, _defec-tion_, not _defect-ion_, but _respec-tively_, not _respect-ively_ and _distinc-tion_, not _distinct-ion_.
XIII Never separate _c_ and _g_ from the vowels _e_, _i_, and _y_ upon which their soft sound depends.
XIV Never separate _q_ from _u_, _qu_ is a single sound.
XVII Do not divide words of five or six letters if it can be avoided. Good spacing, however, must be considered of first importance.
XVIII In wide measures (20 ems or more) do not divide so as to end or begin a line with a syllable of two letters. Here again, however, good spacing is the first consideration.
XIX Do not divide words of two syllables pronounced as one, including past participles of short words.
_heaven_ _power_ _prayer_ _beamed_ _often_
XX Avoid additional hyphens in hyphenated words if possible.
_object-lesson_ _fellow-being_ _poverty-stricken_
XXI Do not separate a divisional mark (_a_), (_1_) from the matter to which it pertains.
XXII Do not divide an amount stated in figures.
XXIII Do not divide proper names, especially those of persons, if it can be avoided.
XXIV Do not divide initials or such combinations as _a.m._, _B.C._
XXV Do not divide the last word on a page so as to carry a part of it to the next page.
XXVI Do not divide the last word of the last full line of a paragraph.
XXVII More than two divisions in successive lines should be avoided.
XXVIII Never divide at all if you can help it.
It must always be remembered that good spacing is the first consideration. Nothing is more offensive to the eye of a good judge of printing than bad spacing. "Rivers" of white, dark spots, crowded black text, are very serious blemishes to a page. An ordinary book page is a study in color, the colors employed being black and white. Proper combination, balance, and proportion are as important here as in places where a variety of colors is employed. Many of the foregoing rules must be held subject to the exigencies of proper spacing. A rigid adherence, for example, to the rule that not more than two consecutive lines should end with divided words will not justify a badly spaced, unsightly line. There are many things that look worse than a hyphen at the end of the last full line in a paragraph. Avoidance of dividing the last word on a page, however, would justify even bad spacing, because of the gain to the reader. In the last resort, the interests of the reader must always have first consideration.
