Articles of practical guidance often need diagrams. Trade papers like to
have their articles illustrated with reproductions of record sheets and
blanks designed to develop greater efficiency in office or store
management. If a writer has a little skill in drawing, he may prepare in
rough form the material that he considers desirable for illustration,
leaving to the artists employed by the publication the work of making
drawings suitable for reproduction. A writer who has had training in
pen-and-ink drawing may prepare his own illustrations. Such drawings
should be made on bristol board with black drawing ink, and should be
drawn two or three times as large as they are intended to appear when
printed. If record sheets are to be used for illustration, the ruling
should be done with black drawing ink, and the figures and other data
should be written in with the same kind of ink. Typewriting on blanks
intended for reproduction should be done with a fresh record black
ribbon. Captions are necessary on the back of drawings as well as on
photographs.

MAILING PHOTOGRAPHS AND DRAWINGS. It is best to mail flat all
photographs and drawings up to 8 x 10 in size, in the envelope with the
manuscript, protecting them with pieces of stout cardboard. Only very
large photographs or long, narrow panoramic ones should be rolled and
mailed in a heavy cardboard tube, separate from the manuscript. The
writer's name and address, as well as the title of the article to be
illustrated, should be written on the back of every photograph and
drawing.

As photographs and drawings are not ordinarily returned when they are
used with an article that is accepted, writers should not promise to
return such material to the persons from whom they secure it. Copies can
almost always be made from the originals when persons furnishing writers
