The great thing which distinguishes the genius from the ordinary man, we repeat, is his power of constant improvement; and we can trace this improvement here from achievements less than those of many a modern writer up to the noblest masterpieces of all time.

Much of the material connected with this development has already been discussed in another connection under Internal Evidence. Internal evidence, however, that one play is later than another, is nothing else than the marks of intellectual growth in the poet's mind between those two dates. We arrange the plays in order according to indications of intellectual growth, just as one could fit together again the broken fragments of a nautilus shell, guided by the relative size of the ever expanding chambers. So, in discussing Shakespeare's development, we must bring up much old material, examining it from a different point of view.

Meter.—In the first place, the poet develops wonderfully in the command of his medium of expression; that is, in his mastery of meter. What is meant by the fact that as Shakespeare grew older, wiser, more experienced, he used more run-on lines, more weak endings, more feminine endings? Simply this, that by means of these devices he gained more variety and expressiveness in his verse. A passage from his early work (in spite of much that is fine) with every ending alike masculine and strong, and with every line end-stopped, harps away tediously in the same swing, like one lonely instrument on one monotonous note. His later verse, on the other hand, with masculine and feminine endings, weak ones and strong, end-stopped and run-on lines, continually relieving each other, is like the blended music of a great orchestra, continually varying, now stern, now soft, in harmony with the thought it expresses. Below are given two passages, the first from an early play, the second from a late one. In print one may look as well as the other; but if one reads them aloud, he will see in a moment how much more variety and expressiveness there is in the second, especially for the purposes of acting.

"Urge not my father's anger, Eglamour,
But think upon my grief, a lady's grief,
And on the justice of my flying hence,
To keep me from a most unholy match,
Which heaven and fortune still rewards with plagues.
I do desire thee, even from a heart.
As full of sorrows as the sea of sands,
To bear me company and go with me;
If not, to hide what I have said to thee,
That I may venture to depart alone."
Two Gentlemen of Verona, IV, iii, 27-36.

"By whose aid,
Weak masters though ye be, I have bedimm'd
The noontide sun, call'd forth the mutinous winds,
And 'twixt the green sea and the azur'd vault
Set roaring war; to the dread rattling thunder
Have I given fire, and rifted Jove's stout oak
With his own bolt; the strong-bas'd promontory
Have I made shake, and by the spurs plucked up
The pine and cedar; graves at my command
Have wak'd their sleepers, op'd, and let 'em forth
By my so potent art. But this rough magic
I here abjure, and, when I have requir'd
Some heavenly music, which even now I do,
To work mine end upon their senses that
This airy charm is for, I'll break my staff,
Bury it certain fathoms in the earth,
And deeper than did ever plummet sound
I'll drown my book."
Tempest, V, i, 40-57.

The same reason shows why Shakespeare used less and less rime as his taste and experience ripened. Rime is a valuable ornament for songs and lyric poetry generally; but from poetry which is actually to be acted on the English stage it takes away the most indispensable of all qualities, the natural, life-like tone of real speech. Notice this in the difference between the two extracts below. Observe how stilted and artificial the first one seems; and see how the second combines the melody and dignity of poetry with the simple naturalness of living language.

"This fellow pecks up wit as pigeons pease,
And utters it again when God doth please.
He is wit's pedler, and retails his wares
At wakes and wassails, meetings, markets, fairs;
And we that sell by gross, the Lord doth know,
Have not the grace to grace it with such show.
This gallant pins the wenches on his sleeve;
Had he been Adam, he had tempted Eve."
Love's Labour's Lost, V, ii, 315-321

"I was not much afeard; for once or twice
I was about to speak and tell him plainly
The self-same sun that shines upon his court
Hides not his visage from our cottage, but
Looks on all alike. Will't please you, sir, be gone?
I told you what would come of this. Beseech you,
Of your own state take care. This dream of mine—
Being now awake, I'll queen it no inch farther,
But milk my ewes and weep."
Winter's Tale, IV, iv, 452-400.

I do not mean to imply by the above that Shakespeare's early verse is poor according to ordinary standards. It is not; it contains much that is fine. But it is far inferior to his later work, and it is inferior in those very details which time and experience alone can teach.
