Classic Poem

'Mid my gold-brown curls
There twined a silver hair:
I plucked it idly out
And scarcely knew 'twas there.
Coiled in my velvet sleeve it lay
And like a serpent hissed:
" Me thou canst pluck and fling away,
One hair is lightly missed;
But how on that near day
When all the wintry army muster in array? "
