What stories does Ichabod tell at the party?

From the text:

All these tales, told in that drowsy undertone with which men talk in the dark, the countenances of the listeners only now and then receiving a casual gleam from the glare of a pipe, sank deep in the mind of Ichabod. He repaid them in kind with large extracts from his invaluable author, Cotton Mather, and added many marvellous events that had taken place in his native State of Connecticut, and fearful sights which he had seen in his nightly walks about Sleepy Hollow.
