Gopi - Uhm---m, 100 metres? No, it is much more, Can't say.
Victoria - It must be more than half a kilometre.
Ms. Asha - Look, it is written - 'This bridge is 756.82 metres long'. So we can guess that the Narmada must be about 500 metres wide at this place.
- Was Victoria right?
Sadaf - I just can't imagine 500 metres.
Ms. Asha - See, our bus is about 5 metres long. Imagine how many buses can stand in a line on this bridge.

Everyone looks down at the river.

After the buses are refilled, the journey starts again. Now the children are told that they are stopping at Bhimbetka.
Anjan - What is Bhimbetka?
Ms. Raina - It's a place with lots of caves and cave-paintings made by people ten thousand years ago.
Sumonto - Tentho _ uu _ saa _ nd years! I cannot even think of one thousand years back!
Gopi - Oh! one thousand years is a big thing, I can't even think of one hundred years.
Gauri - I can think of 100 years because my father's grandmother is 100 years old.
Manjeet - That means those caves are almost hundred great grandmothers old!!
Everybody bursts into laughter - Ha! Ha! Ha!
Now the children are really excited to see the cave-paintings. It is about 11 o' clock when they reach Bhimbetka.
Shankar - This painting also has very big bisons. Hey, I got an idea. I will count the bisons and you count the deer in the paintings.
Bonomala - I will count people. Let us see which are the most - bisons, deer or people.
