Ghosts Who Went To School by Judy Spearing, 6th Scholastic paperback printing, TX965, 1972, 160 pages. Illustrated by Marvin Glass.
DESCRIPTION: “What would you do if a ghost came to your class?
One day, Mrs. Hartley gets a new pupil. From the moment Wilbur the ghost floats through the door, things begin to happen. Wilbur doesn’t mean to make trouble, but suddenly books rise in the air, pencils write by themselves, and mysterious voices answer the teacher.
Wilbur doesn’t understand why anyone’s upset. He just loves going to school.
P.S. Wilbur is very good in arithmetic, but he needs help in spelling.” (from the back cover)
