[Illustration: PLATE XV.
Example of a formal style of pen lettering, with built-up capitals.
The original was hand lettered by George H. Smith and was printed in
two colors. The title, “The Country Boy’s Creed,” and the initial “I”
were printed in red. The rest of the text was printed in green-black
ink. Deep cream paper was used.]
4. _Add the Illustrations._ The ideal booklet is “all of a
piece”--all done by hand. If the illustrations are such as can
be easily copied, or if they can be original, the whole will be
consistent throughout.
In copying pictures two devices are often of great assistance--the
diagonal and the net.
[Illustration: (Different size rectangles with the same diagonal)]
_The Diagonal_--Let the rectangle A-B-C-D in the diagram represent
the shape of picture to be copied. A diagonal drawn in this rectangle
will locate corners of similar rectangles. Suppose the size of the
picture is to be reduced, let us say, to 3 inches. Measure off the
3 inches on the line A-B, as indicated. Through E draw E-F parallel
to B-C and draw F-G parallel to C-D. A-E-F-G is the size and shape
of the reduction. Or, suppose the picture is to be enlarged, let
us say, to 4½ inches. Measure 4½ inches downward from A on
the extension of the line A-B, and find the point H. Proceeding
as before, A-H-I-K is the required rectangle. If the width is the
known dimension, 4 inches, let us say, to which the picture is to be
enlarged, begin with the width as indicated at the top, and proceed
as usual. A-N-M-L is the rectangle.
_The Net._ Divide the picture to be copied into a convenient number
of rectangles of equal size, after the manner shown in Plate XVI,
first into halves, then into quarters, and, if necessary, eighths,
each way. Number and letter the lines as indicated. Having found by
means of the diagonal the correct size and shape of the copy desired,
divide that rectangle to correspond, into halves, quarters, eighths,
each way, and mark the lines with corresponding figures and letters.
If the side of a window falls on line _b_ between 2 and 3 in the
original, it must be located there in the copy. If the outline of the
mountainside crosses line _b_ half way between the top and line 1 in
the original, it must cross the corresponding line in a corresponding
place in the copy. By this means every important feature of the
picture may be readily located in the copy.
