The Lowest Trees Have Tops

The lowest trees have tops, the ant her gall 
The fly her spleen, the little spark his heat; 
The slender hairs cast shadows, through but small, 
And bees have stings, although they be not great; 
Seas have their source, and so have shallow springs; 
And love is love, in beggars and in kings. 

Where waters smoothest run, there deepest are the fords, 
The dial stirs, yet none perceives it move; 
The firmest faith is found in fewest words, 
The turtles cannot sing, and yet they love; 
True hearts have ears, and eyes, no tongues to speak; 
They hear, and see, and sign, and then they break
