A new young wife's spirited reaction to an encounter with life ""down under"" provides reading with a dash of vinegar to sharpen its appeal. Mulaika met Bert Corben when he was studying in California on a grant which stipulated that he must not marry-ride a plane and must spend two years afterwards on British territory. Off to teach in his native Australia, Bert had to upset another nonmarriage clause and to shock his patriotic parents with news of an American wife. Mulaika's life as an Australian housewife and as ""Mrs. Dean"" was curbed by restraints allotted to the ladies (knitting and voluntary confinement during pregnancy at the college) and burdened with tasks unlightened by our gadgets. Her efforts to market in the open or at the call of Milk-O, to teach her botany pupil about aborigines, to keep the college bettors informed as to times of childbirth, and her comments on the verbal and living accents of the Aussies add up to pretty ""fair dinkum"". She doesn't mention kangaroos but with talk on people and taxes, koalas and kiwis and penguins, one certainly doesn't miss them at all. For the alert fellow-female.
