To answer Peter Rabbit's questions about his relatives, Old Mother Nature holds a school for the animals every day at sun-up for a month. Encouraging the animals to notice the differences between them and to offer their observa-tions of animal behavior, Old Mother Nature helps them all gain a greater understanding of the mammals of North America. Starting with the animals close to home, the school moves in ever-widening circles to encompass the animals of the far west and the extreme north, as well. A fine introduction to mammals for students in the primary grades.
