In Farm yard Sounds, the sheep, hen, duck, horse, pig, and cow make their noise either to frighten or to amuse whatever diminutive creatures happen to be in the vicinity. In Jungle Sounds, a hippo, panther, bear (an unusual choice for representing jungle life), tiger, snake, and crocodile make ferocious noises when teased by an insect or smaller ani mal. The pastel colored illustrations are zany: cartoon-like animals with bug- eyes, daffy smiles, and slapstick move ments. None of the atmosphere of the jungle or the farmyard is suggested; the animals sit on a little grass on a white page, in isolation from their habitats. The animals make noises as a result of witless bedevilment or uproariously manic intrusion. A child young enough and inexperienced enough to need an introduction to animal sounds may be confused or even misinformed by the book's cartoonish approach: is a hippo really a silly snoozer who responds with a crazed, clownish snort when a goofy-looking spider tickles it with a feather?Lisa Bliss, Fitchburg Youth Library, Westborough, Mass.
