In "The Legend of Sleepy Hollow", what are two things Brom Bones does to get back at Ichabod for trying to steal Katrina?

In "The Legend of Sleepy Hollow," Brom Bones plays tricks on Ichabod Crane in order to pay Ichabod for trying to steal Katrina.  He stuffs the chimney of the schoolroom so that it redirects the smoke throughout the classroom, and Brom and his friends break into the schoolhouse, turning everything topsy-turvy.  He procures a whining, howling dog as an antidote to Ichabods's singing of the psalms, as well.
