Esop this fable did relate.
A ship by raging tempests tost,
The seamen, giving all for lost,
Twas who should weep and pray the most.
Grown calm at once the sky and sea,
They shout in joyful extacy.
The Pilot, from experience wise,
The giddy crew did thus advise:
"Nor much rejoice, nor over grieve,
But decently what comes receive;
Since good and ill succeed so near,
Meet ill with hope and good with fear."
