In a pleasant variation on an old standby--a book about familiar animals and what they ""say""--animals around an English farmyard are introduced one by one on the right-hand pages (""It's a perfect day to eat some corn, thought the mouse. Squeak squeak!"") while the animals accumulate at the left, their miniature pictures standing in for their names. As framing device, the sun rises and sets over group portraits of all ten animals. Pizer's appropriately realistic illustrations are rather undistinguished but imaginately posed. An attractive, useful lap book.
