Friday, new-born calf and the youngest member of the farm, was tired of always being called ""silly little calf."" He wanted to go out and find the world, which, he had been told, was something round. Several times Friday thought he had made his discovery, but what seemed to be the world turned out only to be a lunch basket, a drainpipe, and the reflection of the moon in a pond. Nobody called him silly and more, however, for he did manage to knock down a thief and to lead Adrian, the farmer's son, to the missing money. Imaginative touches provide a fresh approach to the familiar barnyard scene. The younger members of this age group can easily follow the simple text and will enjoy the gently amusing story. The illustrations are small, scattered pen-and-ink sketches which are quaint but not very memorable.
