To Marguerite: Continued

BY MATTHEW ARNOLD

Yes! in the sea of life enisled,

With echoing straits between us
thrown,

Dotting the shoreless watery wild,

We mortal millions live alone.

The islands feel the enclasping
flow,

And then their endless bounds they

Is to their farthest caverns sent;

For surely once, they feel, we were

Parts of a single continent!

Now round us spreads the watery
plain—

Oh might our marges meet again!

Who ordered, that their longing’s
fire

Should be, as soon as kindled,
cooled?

Who renders vain their deep
desire?—

A God, a God their severance ruled!

And bade betwixt their shores to be

The unplumbed, salt, estranging
sea.

Every blackning Church
appalls, 

And the hapless Soldiers sigh

Runs in blood down Palace
walls 

But most thro’ midnight streets I
hear

How the youthful Harlots curse

Blasts the new-born Infants
tear 

And blights with plagues the Marriage hea
