farther along in the essay were to be found such straightforward
sentences as these: Air has a faint bluish tint which on a sunshiny
day becomes in the sky a very pure and deep blue. This tint is not
believed to be the natural color of the atmosphere. Were it such,
the air would act the part of a blue pane of glass, rendering the
white light of the sun blue as it reached our eyes. The blue of the
air is thought to be a reflected blue. If reflected, there must be
something in the air to reflect it; and such indeed is the case.
Perfectly pure air would doubtless be without color, but perfectly
pure air we do not find. Etc. Here at last was stuff of the right
sort?good matter and a good manner. What the writer had failed to
realize, as his introduction showed, was that such simple
statements of fact concerning the atmosphere as would satisfy a
teacher of chemistry or of physics would satisfy a teacher of
composition?just that and nothing more or less. He had not yet
learned that composition must not be detached from the other
activities of hand or brain, in school or out. 4. Limitation of the
Subject. Another point is suggested by this last subject. The
subject is of the right nature, but it is too broad to be treated
in an ordinary school essay. Nothing short of a volume would
warrant the selection of such an unqualified theme as " Air." The
briefer the title the broader the theme, and consequently the
fuller the treatment demanded. The theme before us might have been
narrowed in many ways. The writer might have confined himself to
the chemical composition of air, to its physical properties, or to
its relation to organic life. " The Blue Color of the Atmosphere "
would constitute a good subject in itself. Narrowing the theme is
not only a proper measure to take when ...
