What does the note say that Jem and Dill give Boo Radley?

Jem and Dill get the idea to write a note to Boo Radley asking him to come outside and tell them what he does inside his house. Furthermore, they write that they will buy him an ice cream and will not hurt him. They put the note on the end of a fishing pole and try to attach it to a window shutter on the side of Boo's house.
