Now
imagine a mountain of that sand, a million miles high, reaching from
the earth to the           heavens, and a million miles broad,
extending to remotest space, and a million miles in thickness;
and imagine such an enormous mass of countless particles of sand
multiplied as often as there are leaves in the forest, drops of water
in the mighty ocean, feathers on birds, scales on fish, hairs on
animals, atoms in the vast expanse of the air: and imagine that at the
end of every million years a little bird came to that mountain and
carried away in its beak a tiny grain of that sand.
