The lowest trees have tops - Third Booke of Songes, 1603, no19
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
