And strength of ripening brain,
Till rose the form that grasped the world
And made it his domain.

Yea, with red feud and ravage
Of saber tooth and claw.
With banding of the pack for might
And filled or starving maw;
From floundering saurians welter,
Through grin and screech of ape,
Struggled the deathless seed of life
Up to human shape.

And man hath made with labor:
From his wild primal hour,
Potent with transforming deeds.
He hath wed will to power;
Through war and peace untiring,
To industry and art,
Spending the might of all his thought
And the hope of all his heart.

Yea, tried in stress of effort
And passions wise and vain,
His zeal hath gathered wisdoms seed
From fruits of joy and pain.
His millioned cities echo;
His ships have pathed the sea;
And with bent brow he toils to make
The world that yet will be.
