are calculated to afford important aid; and Professor Mark Bailey, in his
Introduction to "Hillard's Sixth Reader," has still further simplified the
subject. The following principles which he lays down for regulating the
inflections are at once comprehensive and practical.

"The 'rising' and 'falling' slides separate the great mass of ideas into
two distinct classes; the first comprising all the subordinate, or
incomplete, or, as we prefer to name them, the negative ideas; the second
comprising all the principal, or complete, or, as we call them, the
positive ideas.

"The most important parts of what is spoken or written, are those which
affirm something positively, such as the facts and truths asserted, the
principles, sentiments, and actions enjoined, with the illustrations, and
reasons, and appeals, which enforce them. All these may properly be grouped
into one class, because they all should have the same kind of slide in
reading. This class we call 'positive ideas.'

"So all the other ideas which do not affirm or enjoin anything positively,
which are circumstantial and incomplete, or in open contrast with the
positive, all these ideas may be properly grouped into another single
class because they all should have the same kind of slide. This class we
call 'negative ideas.'

"Positive ideas should have the falling slide; Negative ideas should have
the rising slide.

"All sincere and earnest, or, in other words, all upright and downright
ideas demand the straight, or upright and downright slides.
