to produce effects not attained by the process work. The skill of the
artist in making the drawing thus becomes all important.

[Later Inventions]

The introduction of color work in the schoolbooks intended for young
children resulted from the invention of the three-color plates. From
nature, or from a colored painting, three photographs are taken--one

which to the eye in many cases look exactly alike. From one of these
an impression is made with yellow ink, exactly over this the red plate
prints with red ink and this is followed by an impression from the blue
plate. If the effects of the color screens of the camera are exactly
reproduced by the printer's inks and with exactly the right amount of
ink, the result is wonderfully satisfactory.

What are the qualities in these McGuffey Eclectic Readers that won for

The best answer to this question may be drawn from the many newspaper
articles which appeared in Western and Southern papers after the death

writers of these articles that while the books served well their purpose
of teaching the art of reading, their greatest value consisted in the
choice of masterpieces in literature which by their contents taught
morality, and patriotism and by their beauty served as a gateway to pure
literature. One editor, who used these books in his school career, said,
