The Arrow and the Song by Henry Wadsworth Longfellow

I shot an arrow into the air,
It fell to earth, I knew not where;
For, so swiftly it flew, the sight
Could not follow it in its flight.

I breathed a song into the air,
It fell to earth, I knew not where;
For who has sight so keen and strong,
That it can follow the flight of song?

Long, long afterward, in an oak
I found the arrow, still unbroke;
And the song, from beginning to end,
I found again in the heart of a friend.

Lines by Martha Collins

Draw a line. Write a line. There.
Stay in line, hold the line, a glance
between the lines is fine but don't
turn corners, cross, cut in, go over
or out, between two points of no
return's a line of flight, between
two points of view's a line of vision.
But a line of thought is rarely
straight, an open line's no party
line, however fine your point.
A line of fire communicates, but drop
your weapons and drop your line,
consider the shortest distance from x
to y, let x be me, let y be you.

Fire and Ice by Robert Frost

Some say the world will end in fire,
Some say in ice.
From what I've tasted of desire
I hold with those who favor fire.
But if it had to perish twice,
I think I know enough of hate
To say that for destruction ice
Is also great
And would suffice.
