Her aunt smiled. "I don't know, Anna. I think you had better go to Vosborg again in the daytime. Then you can find out for yourself whether or not it has any ghosts."
CHAPTER VII
A DAY AT THE SHORE
"Why don't you have a windmill on your farm, Uncle Frederick?" asked Anna. "Every one of these farms has a big windmill."
Anna and her uncle and Greta were driving through the country on their way to the shore. Greta's father had to make a business trip to a small town on the coast, and he was taking the girls with him. Chouse was comfortably curled up on the back seat.
"We don't need a windmill, Anna, because we have the river."
"But how can the river take the place of a windmill?" asked Anna.
"Greta, haven't you shown Anna the dam in the river?" asked her father. "This dam causes the water to fall from a great height. The force of the water, as it falls on a large machine, provides the power that is turned into electricity. These other farms get their electric power from the windmills. As the great arms are turned by the wind, they provide power that is changed, by the machinery, into electricity."
