Answer:
Large as a mountain, small as a pea, Endlessly swimming in a water-less sea.
A house full, a yard full, a chimney full, no one can get a spoonful.
What can be heard and caught but never seen?
My tongue hangs out as I run over fields and streets all day. I get tied up every morning and untied at night.
What relies on columns but isn't a house, and asks for help but can't speak itself?
What is always coming but never arrives?
