FROM THE GERMAN OF GEIBEL.

() THOU, at whose command divine
The raging storms of ocean cease,
This wild, unruly heart of mine
Lead to thine everlasting peace ;
This heart, that only feels the glow
That every changing passion lends,
And, through its erring love, brings woe
Alike upon itself and friends.
Deliver it, good Lord, I pray
From passions' storm ; O quench the fire
Of sinful lust, and break the sway
Of every passing vain desire;
Give it, O Lord, a changeless aim,
That, in the contemplation blest,
Forgetting doubt, and fear, and shame,
It may at last find endless rest.

Why are the tremulous leaves a-sway
On the trees new fledge with the faintest

Nay, he were wise who could say what

these things mean,

and tell the secret of May.
What is my heart trying to say ?
Why does it tremble and hurry and stay
At the sight of a leaf on a sunny day,

Of a leaf tho' never so delicate green ?
