What treasure, uncle?

What treasure, uncle?
Exeter
Tennis balls, my liege.
King Henry
We are glad the Dauphin is so pleasant with us.
His present and your pains we thank you for.
When we have matched our rackets to these balls,
We will in France, by God’s grace, play a set
Shall strike his father’s crown into the hazard.

And some are yet ungotten and unborn
That shall have cause to curse the Dauphin’s scorn.

Tell him he hath made a match with such a wrangler
That all the courts of France will be disturbed
With chases. And we understand him well,
How he comes o’er us with our wilder days,
Not measuring what use we made of them.
We never valued this poor seat of England,
And therefore, living hence, did give ourself
To barbarous license, as ’tis ever common
That men are merriest when they are from home.
But tell the Dauphin I will keep my state,
Be like a king, and show my sail of greatness
When I do rouse me in my throne of France,
For that I have laid by my majesty
And plodded like a man for working days;
But I will rise there with so full a glory
That I will dazzle all the eyes of France,
Yea, strike the Dauphin blind to look on us.
And tell the pleasant prince this mock of his
Hath turned his balls to gun-stones, and his soul
Shall stand sore chargèd for the wasteful vengeance
That shall fly with them; for many a thousand widows
Shall this his mock mock out of their dear husbands,
Mock mothers from their sons, mock castles down;
And some are yet ungotten and unborn
That shall have cause to curse the Dauphin’s scorn.
But this lies all within the will of God,
To whom I do appeal, and in whose name
Tell you the Dauphin I am coming on,
To venge me as I may and to put forth
My rightful hand in a well-hallowed cause.
So get you hence in peace. And tell the Dauphin
His jest will savor but of shallow wit
When thousands weep more than did laugh at it.—
Convey them with safe conduct.—Fare you well.
