He must get on without any attempt to point out the morality of his
work, which remains implicit altho it ought to be obvious. He must work
easily within many bonds, seeming always to be free and unhampered; and
he must turn to account these restrictions and find his profit in them,
for they are the very qualities which differentiate the drama and make
it what it is.

This essential unlikeness of the drama to the novel is so keenly
appreciated by every novelist who happens also to be a dramatist, that
he is rarely tempted to treat the same theme in both forms, feeling
instinctively that it belongs either to the stage or to the library.
Often, of course, he writes a novel rather than a play, because he knows
that a certain theme, adequate as it may be for a novel, lacks that
essential struggle, that naked assertion of the human will, that clash
of contending desires, which must be visible in a play if this is to
sustain the interest of an audience. Many a tale, pleasing to thousands
of readers because it abounds in brisk adventure, will not lend itself
to successful dramatization because its many episodes are not related to
a single straight-forward conflict of forces.

When Mr. Gillette undertook to make a play out of the Sherlock Holmes
stories, which were not really dramatic, however ingeniously packed with
thrilling surprizes, he seized at once on the sinister figure of

mastery of a major principle of play-making. Many a novel has seemed
vulgarized on the stage, because the adapter had to wrench its structure
in seeking a struggle strong enough to sustain the framework of a play.
Many a story has been cheapened pitifully by the theatrical adapter,
simply because he was incapable of seeing in it more than a series of
