They both get drawn into a hole along with a
swift stream of water and gently flow downwards, sometimes fast, sometimes slow, through
holes and cracks and passages of all kinds, deeper and deeper into the ground.
Chhutki : (Pointing at the walls of
the tunnel through which they are floating.)
Baadshah , look! The colour of the earth in these tunnels and passages keeps changing as
we go deeper.
Baadshah : Yes, Chhutki. The Earth is
made up of many layers of rocks, soil and other materials in all sizes from large rocks to
fine dust. These act as a wonderful filter made by Nature.
Chhutki : Filter?
Baadshah : Yes. Rain water from the
surface of the earth passes through the soil, just as we are doing now. As it passes
through, all the dirt and impure particles are trapped by the layers of the soil,allowing
only pure, clean water to pass down the underground layers to where it collects. And, we
are about to reach that place any moment now. Hang on!
