। ॥ १८ ॥
In plain words
Bulls, horses, donkeys, elephants, buffaloes — driven on and on without a break, starving, worked to the end of their strength. "Ah, the pain of it" — they cannot even say that much.
Close to the Sanskrit
By bulls, horses, donkeys, elephants, buffaloes constantly being driven, by those craving food and utterly wearied, 'Ah! The pain!' cannot even be spoken.
