The excerpt represents the core issue or deciding factor on which you must meditate, and is drawn from Georgics by Virgil:|
Stalks on the dry sand mateless and alone.
Nor e'en the maids, that card their nightly task,
Know not the storm-sign, when in blazing crock
They see the lamp-oil sputtering with a growth
Of mouldy snuff-clots.
So too, after rain,
Sunshine and open skies thou mayst forecast,
And learn by tokens sure, for then nor dimmed
Appear the stars' keen edges, nor the moon
As borrowing of her brother's beams to rise,
Nor fleecy films to float along the sky.
