Arlo Janssen, the author of PARSONAGE IN A PEAR TREE, writes about his being brought up in a small town in Minnesota in the 1930's and early 40's. The large family, of which he was number seven, lived in a parsonage, next to the church, where his father was the pastor Though the family was poor, humor abounded in their home life. They were able to smile in virtually all circumstances. The title of the book comes from their singing, as a joke, the "Twelve Days of Christmas" with the words, "And a Parsonage In a Pear Tree." The book contains episodes and information from the life of the children in the family, especially the youngest. Arlo, number seven of ten siblings, was ''the oldest of the youngest.'' Some episodes are touching; some are humorous; all are interesting. People who have been brought up in small towns say, when they read the book, that they can identify with almost everything. PARSONAGE IN A PEAR TREE is not Christian book, as such; however, it definitely has a heartwarming Christian message in various chapters. The Janssens were all committed Lutheran Christians.
