Reflection - L A Ransom

Reflection so pure
Upon still Lake,
But when Pebble falls
The Waters do shake,
And Reflection so pure
At once does it break,
A thousand many pieces
Such a Wave will make,
Then the Pond stills
So far from opaque,
The River does give,
Entrance and then take,
Calm it may seem
Yet all this is fake,
A side not often seen
Only a Pebble can awake.
