No More Learning

For I have seen
The thorn frown rudely all the winter long
And after bear the rose upon its top;
And bark, that all the way across the sea
Ran           and speedy, perish at the last,
E'en in the haven's mouth seeing one steal,
Another brine, his offering to the priest,
Let not Dame Birtha and Sir Martin thence
Into heav'n's counsels deem that they can pry:
For one of these may rise, the other fall.
