Take a magnifying glass and go out into the world of insects and flowers, birds and snakes with Mr. Headstrom. Unhurriedly he roams the New England wood and field beyond his door through the seasons, sees the buds and leaf scars of trees in January, the whirligig beetles in March, the dogwood of May, September mushrooms. He has in hand an assortment of facts: the ecological succession from polished rock to forest, the bluet variants, the nature of snake scales. Again he reveals a world made up of many small things to the individual who wants to see and know. An eye-opener.
