The business letter is commonly keyed on a letterhead,
a form that has a preprinted heading.  Usually this heading
includes both the name and address of the company for which
the letter is being keyed.  Thus, the keyboarder needs only
to key in the date to complete the heading.  The letterhead
is used only for the first page of a letter.  If there is a
second letter page, this page and any additional pages that
might follow, are keyed on plain stationery.  However, each
page of the letter that follows the letterhead must possess
a paper quality that closely equals that of the letterhead.
     The second and subsequent pages of any business letter
should be provided a heading.  The heading correctly begins
on line seven in order to provide for a one inch top margin
on the page.  The initial line is to identify the recipient
of the letter.  The second heading line, that must be keyed
below the first if the vertical arrangement is used, states
the correct page number in numeral form.  The final line of
the heading indicates the date of the letter.  This heading
date must, of course, agree with the date positioned on the
letterhead.  A keyed heading is followed by a triple space.
