DIAGONAL INDENTION
When two or more words intended for display in a poster or an advertisement are of nearly the same length, and are of equal value, but cannot be set in one line properly, and cannot be put in separate and full lines without making a display too bold for the occasion, nor centred without awkwardness of effect, they may be arranged diagonally in this fashion:
COURIER
GAZETTE
TRIBUNE
This can be done with a better effect when there is ample space for the use of leads to separate lines, but the triangular gaps of white do not favor easy composition on the side. Advertisers often fill the blanks with small type.
In a circular of plain and undisplayed type, the diagonal indention is wisely used for the address of corporations or societies which have titles too long to be arranged in one or two lines. It is the proper method for composing type in imitation of the superscription of the address on an envelope.
IRREGULAR INDENTION
Extracts inserted in the body of the text are often indented evenly with one em or two ems on each
