in style of type is enough to show separation of subject. This needless use of the dash probably began with the copying of a similar dash unthinkingly put in his copy by the author.
LETTER HEADINGS IN SMALL CAPITALS
In reprinting letters, the name of the town or city in which the letter was written, and of the person or firm to whom the letter was addressed, as well as the signature of the writer, are often put in capitals and small capitals. The name of the month and the day and date, although oftenest by the side of the place, are put in lower-case of the text letter. This is the rule in the composition of job-work and advertising pamphlets, but it is not a good rule for newspapers or books. In the bookhouse small capitals should be considered as a letter of modified display, to be used only when demanded by words that need special distinction. The complimentary salutation of Dear Sir or Gentlemen does not need small capitals. When the printed heading of a letter is unusually long, as it is in the following examples, lower-case is preferable.
