To murmur through the heaven-breathing groves 370 And melodise with man's blest nature there. The vast tract of the parched and sandy waste Now teems with countless rills and shady woods, Corn-fields and pastures and white cottages; And where the startled wilderness did hear 375 A savage conqueror stained in kindred blood, Hymmng his victory, or the milder snake Crushing the bones of some frail antelope Within his brazen folds—the dewy lawn, Offering sweet incense to the sunrise, smiles 380 To see a babe before his mother's door, Share with the green and golden basilisk That comes to lick his feet, his morning's meal.

Even where the milder zone afforded man A seeming shelter, yet contagion there, 420 Blighting his being with unnumbered ills, Spread
