A nursery school approach to a general concept. "A tree is nice"- Why? Because..."We can climb the tree...play pirate ship...pick the apples...build playhouses out of the leaves. A tree is nice to hang a swing in...Birds build nests in trees... Sticks come off trees...People have picnics there too"...etc. etc. One follows the give and take of a shared succession of reactions to what a tree- or trees- can mean. There is a kind of poetic simplicity that is innate in small children. Marc Simont has made the pictures, half in full color, and they too have a childlike directness (with an underlying sophistication that adults will recognize). Not a book for everyone -but those who like it will like it immensely. The format (6 x 11) makes it a difficult book for shelving, so put it in the "clean hands" section of flat books. Here's your first book for Arbor Day use- a good spring and summer item.
