Sweep beds of ore, and leave their gold behind,
In headlong cataracts indignant rave,
Rush to his banks and swell the swallowing wave.
Ucayla, first of all his mighty sons,
From Cusco's walls a wearied journey runs;
Pastaza mines proud Pambamarca's base,
And holds thro sundering hills his lawless race;
Aloft, where Cotopaxa flames on high,
The roaring Napo quits his misty sky,
Down the long steeps in whitening torrents driven,
Like Nile descending from his fabled heaven;
Mound after mound impetuous Tigris rends,
Curved Ista folds whole countries in his bends;
Vast Orinoco, summon'd forth to bring
His far fetch'd honors to the sateless king,
Drives on his own strong course to gain the shore,
But sends Catuba here with half his store;
Like a broad Bosphorus here Negro guides
The gather'd mass of fifty furious tides;
From his waste world, by nameless fountains fed,
Wild Purus wears his long and lonely bed;
O'er twelve degrees of earth Madera flows,
And robs the south of half its treasured snows;
Zingus, of equal length and heavier force,
Rolls on, for months, the same continuous course
To reach his master's bank; that here constrains
Topayo, charged with all Brazilians rains;
While inland seas, and lakes unknown to fame,
Send their full tributes to the monarch stream;
Who, swell'd with growing conquest, wheels abroad,
