y unexciting, the scenes of lower tension may be as long as
those of higher; while in a portion of the play which is specially
exciting the scenes of low tension are shorter, often much shorter, than
the others. The reader may verify this statement by comparing the First
or the Fourth Act in most of the tragedies with the Third; for, speaking
very roughly, we may say that the First and Fourth are relatively quiet
acts, the Third highly critical. A good example is the Third Act of
_King Lear_, where the scenes of high tension (ii., iv., vi.) are
respectively 95, 186 and 122 lines in length, while those of low tension
(i., iii., v.) are respectively 55, 26 and 26 lines long. Scene vii.,
the last of the Act, is, I may add, a very exciting scene, though it
follows scene vi., and therefore the tone of scene vi. is greatly
lowered during its final thirty lines.

(2) If we turn now from the differences of tension to the sequence of
events within the conflict, we shall find the principle of alternation
at work again in another and a quite independent way. Let us for the
sake of brevity call the two sides in the conflict A and B. Now,
usually, as we shall see presently, through a considerable part of the
play, perhaps the first half, the cause of A is, on the whole,
advancing; and through the remaining part it is retiring, while that of
B advances in turn. But, underlying this broad movement, all through the
conflict we shall find a regular alternation of smaller advances and
retirals; first A seeming to win some ground, and then the
counter-action of B being shown. And since we always more or less
decidedly prefer A to B or B to A, the result of this oscillating
movement is a constant alternation of hope and fear, or rather of a
mixed state predominantly hopeful and a mixed state predominantly
apprehensive. An example will make the point clear. In _Hamlet_ the
conflict begins with the hero's feigning to be insane from
disappointment in love, and we are shown his immediate success in
convincing Polonius. Let us call this an advance of A. The next scene
shows the King's great uneasiness about Hamlet's melancholy, and his
scepticism as to Polonius's explanation of its cause: advance of B.
Hamlet completely baffles Rosencrantz and Guildenstern, who have been
sent to discover his secret, and he arranges for the test of the
play-scene: advance of A. But immediately before the play-scene his
soliloquy on suicide fills us with misgivin
