I see the Humboldt range, I thread the valley and cross the river,
I see the clear waters of lake Tahoe, I see forests of majestic pines,
Or crossing the great desert, the alkaline plains, I behold
    enchanting mirages of waters and meadows,
Marking through these and after all, in duplicate slender lines,
Bridging the three or four thousand miles of land travel,
Tying the Eastern to the Western sea,
The road between Europe and Asia.

(Ah Genoese thy dream! thy dream! 
Centuries after thou art laid in thy grave,
The shore thou foundest verifies thy dream.)

Passage to India! 
Struggles of many a captain, tales of many a sailor dead,
Over my mood stealing and spreading they come,
Like clouds and cloudlets in the unreach’d sky.

Along all history, down the slopes,
As a rivulet running, sinking now, and now again to the surface rising,
A ceaseless thought, a varied train—­lo, soul, to thee, thy sight,
    they rise,
The plans, the voyages again, the expeditions;
Again Vasco de Gama sails forth,
Again the knowledge gain’d, the mariner’s compass,
Lands found and nations born, thou born America,
For purpose vast, man’s long probation fill’d,
Thou rondure of the world at last accomplish’d.

O vast Rondure, swimming in space,
Cover’d all over with visible power and beauty,
Alternate light and day and the teeming spiritual darkness,
Unspeakable high processions of sun and moon and countless stars above,
Below, the manifold grass and waters, animals, mountains, trees,
With inscrutable purpose, some hidden prophetic intention,
Now first it seems my thought begins to span thee.

Down from the gardens of Asia descending radiating,
Adam and Eve appear, then their myriad progeny after them,
Wandering, yearning, curious, with restless explorations,
With questionings, baffled, formless, feverish, with never-happy hearts,
With that sad incessant refrain, Wherefore unsatisfied soul? and
    Whither O mocking life?

Ah who shall soothe these feverish children? 
Who Justify these restless explorations? 
Who speak the secret of impassive earth? 
Who bind it to us? what is this separate Nature so unnatural? 
What is this earth to our affections? (unloving earth, without a
    throb to answer ours,
Cold earth, the place of graves.)

Yet soul be sure the first intent remains, and shall be carried out,
Perhaps even now the time has arrived.

After the seas are all cross’d, (as they seem already cross’d,)
After the great captains and engineers have accomplish’d their work,
After the noble inventors, after the scientists, the chemist, the
    geologist, ethnologist,
Finally shall come the poet worthy that name,
The true son of God shall come singing his songs.
