The further adventures of Tizz, Tracy Hill's obliging pony, make a pleasant, somewhat innocuous Christmas story. Tizz disappeared when the gate was left open. Kindly old Mr. Adams returned the pony to the Hill family, and through him they heard about Sally, a neighbor's child, ill with polio. Tracy was given the part of Mary in the Christmas Pageant, because Tizz was the best substitute for a donkey to be had. The pony paid a brief visit to the principal's office before the play was over, and when the family car broke down as the family left to take Christmas gifts to Bally, Tizz saved the day.
