The author describes five types of difficult adjustments among children, namely, the troublesome child, the over-conscientious child, the over-dependent child, the over-anxious child, and the child with a polyglandular difficulty. The author evidently thinks that if enough 'facts' are collected, whether relevant or not, useful conclusions will emerge. We are thus given the edifying information about one troublesome child, Ned, that 'Ned's paternal grandfather owned a lumber-yard. He was a capable business man. He died at the age of fifty-two of apoplexy. … Aunt Evelyn, thirty-eight, is married. She has one daughter, aged thirteen.' Nevertheless, he means well and is evidently interested in children. Teachers will find it worth while to read the book.
