THE LEGEND OF SLEEPY HOLLOW On the Eastern shore of the Hudson River there was a little valley, among high hills, which was one of the quietest places in the whole world. This valley had long been known by the name of Sleepy Hollow. Many strange stories about ghosts were told and retold in a village situated there. The most frightful, however, was the one about a headless horse¬man. It is said that it was the ghost of a soldier who had been killed in battle. Once there lived in this village a schoolmaster, Crane by name. He was a tall and very thin man. In the same village lived the daughter and the only child of a rich farmer. She was a pretty girl and attracted the attention of every young man in the village. Crane too, was in love with her. But if the schoolmaster meant to win her heart, he would have to get rid of all his rivals. The one he feared most was a certain Brunt. He was a tall and strong young man and most people liked him for his bravery and great skill of a horseman. It is clear that Crane would have lived quietly in his little village to the end of his life if a very strange thing had not happened one night. In the afternoon of that day Crane was in his school when a servant brought him an invitation to a party, which was to be held that evening at Van Tassel's. The pupils were sent home an hour before the usual time, and Crane spent no less than half an hour dressing up for the party. He wished to look his best that night, therefore, he borrowed a horse from the farmer with whom he was then living. The horse's name was Gunpowder. It was towards evening that Crane arrived at home of Van Tassel. The house was full of guests and Brunt was among them. There were many good things to eat and a lot of dancing. Everybody enjoyed himself that night. When the party was nearly over, Crane suddenly left the hall where the guests were dancing. He went to Katrina's room where he stayed alone with the girl for a short while. They must have had an unpleasant conversation for the school¬master looked sad when he re-entered the hall.
