Mohenjo-Daro of description

Mohenjo-Daro is nearly 400 miles to the north of Karachi and on right bank of the River Indus. It is one of the oldest circles of the world. It people live there to day but 4,000 years ago it was a large, busy city. Nobody knew about it until 1922 when some villagers found some old pots and old bricks from the city. They took them to Sir John Marshall. He was interested in history, in ancient buildings and in old things.
When he had looked at them, he said, perhaps they come from an old city. Perhaps there was once a town or a city at this place. Let us dig there. When we dig and take away the sand, perhaps we shall uncover the building of an old city
