Other stones the era tell,
When some feeble mortal fell;
I stand here to date the birth
Of these hardy sons of earth.
Which shall longest brave the sky,
Storm and frost -- these oaks or I?
Pass an age or two away,
I must moulder and decay;
But the years that crumble me
Shall invigorate the tree,
Spread its branch, dilate its size,
Lift its summit to the skies.
Cherish honour, virtue, truth,
So shalt thou prolong thy youth.
Wanting these, however fast
Man be fixed, and formed to last,
He is lifeless even now,
Stone at heart, and cannot grow.
