The Dutch people live in Holland. They have made dikes to keep the sea from their land.
Do you know what dikes are?
They are huge walls made of stone. They are very large and strong. If a dike should break, the country would be flooded.
There are many canals in Holland. Some of the canals are so large and deep that big ocean steamships can sail on them.
There are many boats on the canals. People live on the boats all the year round.
