Walter Raleigh Quote

Three things there be that prosper all apace,
And flourish while they are asunder far;
But on a day, they meet all in a place,
And when they meet, they one another mar.
And they be these: the Wood, the Weed, the Wag:
The Wood is that that makes the gallows tree;
The Weed is that that strings the hangman's bag;
The Wag, my pretty knave, betokens thee.

'Sir Walter Ralegh to his Son'
