TO CELIA.

Drink to me only with thine eyes,
And I will pledge with mine;
Or leave a kiss in the cup
And I'll not look for wine.
The thirst that from the soul doth rise
Doth ask a drink divine;
But might I of Jove's nectar sup,
I would not change for thine.

I sent thee late a rosy wreath,
Not so much honoring thee
As giving it a hope that there
It could not withered be;
But thou thereon didst only breathe
And sen'st it back to me;
Since when it grows, and smells, I swear,
Not of itself but thee!

--_Ben Johnson._

DON'T FORGET THE TREE.

(A POEM FOR ARBOR DAY.)

How beauteous is the lordly tree
That scatters cooling shade!
The landscape, O how fair and free
By loving Nature made;
The birds that build in leafy bough
Hail each returning spring,
And in the emerald forests now
They make the Welkin ring.
