No More Learning

With time both wiser and sedater too:
For as in spring the swelling stream rolls by,
Foams, dashes o'er its borders furiously,
Then flowing further glides serenely on,
So youth is gay and wild till youth is gone;
Till, taught by thick           and years,
It sheds the excess of blossoms which it bears,
And, shaken by the winds of want and woe,
Its flowers drop off upon the sod below.
