In some parts of Holland the land lies so low that the people have to build great walls of sand and earth, to keep out the sea. These walls are called dykes(堤坝).

Sometimes the water from the sea break down these walls, and then the sea rushes in through the beach, and spreads over the land.

Houses and trees, cows and sheep, have been thus washed away, and many people drowned(溺水).

Once, when a little boy was going home in the evening, he saw a hole in one of the dykes, through which the water was flowing(流出）.

His father had often told him that when this happened, unless the water was stopped it would soon make the bole so big that the sea would flow over the land.

At first he thought he would run home and tell his father. But then he said to himself," It may be dark before father can come, and we shall not be able to find the hole again. Or it may get so large that it will be too late to stop it. I must stay now, and do the best I can alone.

The brave little boy sat down, and put his hand in the hole, to keep back the water. There he stayed, hour after hour, in the cold and the dark, all through the night!

“There is a hole in the dyke,” said the boy,“ and I am keeping back the water.”

Poor little boy! He was so cold and tired that he could hardly speak.

The man came quickly and set him free. He got the hole closed up, and thus the land was saved--thanks to the brave little Hollander!
