student: excuse me, professor, can i ask you a few questions about early farming?

professor: yes, sure. i’ll be glad to help you.

s: how did early farmers cultivate their land?

p: the life of a farmer has never been easy! first, they had to clear a plot of land, and then they dug it using sharp sticks. later on they learned to plough their land; it was a lot more convenient to use a plough than a sharp stick.

s: they had to irrigate their fields, didn’t they? how did early farmers water their fields?

p: they often dug small irrigation canals and connected them to rivers.

s: i see. they were able to organize some kind of water supply. i didn’t know that! but could they actually control the level of water in their irrigation canals?

p: controlling water has always been difficult, but early farmers did their best. they built dams on small rivers to hold back the water. they needed the constant supply of water to grow their  crops. they also needed water for their animals and themselves. for that reason people in those days chose places for their settlements near rivers and lakes.

s: thank you very much, professor! i learn something every day from you.

p: you are welcome. that’s what teachers are for!
