And southern vales prolong the seaward way.
Columbus traced, with swift exploring eye,
The immense of waves that here exalted lie,
The realms that mound the unmeasured magazine,
The far blue main, the climes that stretch between.
He saw Xaraya's diamond banks unfold,
And Paraguay's deep channel paved with gold,
Saw proud Potosi lift his glittering head,
And pour down Plata thro his tinctured bed.
Rich with the spoils of many a distant mine,
In his broad silver sea their floods combine;
Wide over earth his annual freshet strays,
And highland drains with lowland drench repays;
Her thirsty regions wait his glad return,
And drink their future harvest from his urn.

Where the cold circles gird the southern sky.
Brave Magellan's wild channel caught his eye;
The long cleft ridges wall'd the spreading way.
That gleams far westward to an unknown sea.
Soon as the distant swell was seen to roll,
His ancient wishes reabsorb'd his soul;
Warm from his heaving heart a sudden sigh
Burst thro his lips; he turn'd his moisten'd eye,
And thus besought his Angel: speak, my guide,
Where leads the pass? and what yon purple tide?
How the dim waves in blending ether stray!
No lands behind them rise, no pinions on them play.
There spreads, belike, that other unsail'd main
I sought so long, and sought, alas, in vain;
