Uncheck'd in Paraguay it ran its course,
Till all the gentler children of the land
Well nigh had been consumed without remorse.
The bolder tribes meantime, whose skilful hand
Had tamed the horse, in many a warlike band
Kept the field well with bow and dreadful spear.
And now the Spaniards dared no more withstand
Their force, but in their towns grew pale with fear
If the Mocobio, or the Abipon drew near.
Bear witness, Chaco, thou, from thy domain
With Spanish blood, as erst with Indian, fed!
And Corrientes, by whose church the slain
Were piled in heaps, till for the gather'd dead
One common grave was dug, one service said!
Thou too, Parana, thy sad witness bear
From shores with many a mournful vestige spread.
And monumenta crosses here and there
And monumental names that tell where dwellings were!
