Classic Poem

What is hard to hide? the Fire!
For by day the smoke betrays it
And the Flame by night, the monster.
Again 'tis hard our Love to hide,
For howsoever you enclose it,
Out of the eyes it softly smites you.
But hardest 'tis to hide a Poem,
Under no bushel you'll conceal it.
Has but the Poet freshly sung it
Thereby is he quite overcome;
Has he just smartly dash'd it off
He wills, that the whole world shall love it.
To all he reads it glad and loud,
Whether it fret us or instruct.
