Presents essays about the plant and animal life of the author's northeastern Ohio farm

David Kline has been called a "twentieth–century Henry David Thoreau" by his friends and contemporaries; an apt comparison given the quiet exuberance with which he records the quotidian goings–on on his organic family farm. Under David's attentive gaze and in his clear, insightful prose the reader is enveloped in the rhythms of farm life; not only the planting and harvesting of crops throughout the year, but the migration patterns of birds, the health and virility of honeybees left nearly to their own devices, the songs and silences of frogs and toads, the disappearance and resurgence of praying mantises in fields–turned woodlands, the search for monarch butterflies in the milkweed. There's rhythm in community, too—neighbors gathering to plant potatoes or to maintain an elderly friend's tomato garden, organic farming conferences and meetings around family dining tables or university panels. Interspersed with local lore (when the spring's first bumblebee appears the children can go barefoot) is deep technical knowledge of cultivation and land management and the hazards of modern agri–business. Kline records statewide meetings of district supervisors, knows which speakers and committee chairmen are in the pockets of the oil and gas lobbyists, stands up and says his part. At a time when America's population is being turned toward the benefits of small, local farming practices on our health and our environment, Kline's daybook offers a striking example of the ways in which we are connected to our environment, and the pleasure we can take in daily work and stewardship.

For a family with four kids, two dogs, assorted cats, and a constant stream of family and friends dropping by, life in the Austin family home has always been remarkably steady and contented. When a family friend suddenly dies in a plane crash, the Austins open their home to an orphaned girl, Maggy Hamilton. The Austin children—Vicky, John, Suzy, and Rob—do their best to be generous and welcoming to Maggy. Vicky knows she should feel sorry for Maggy, but having sympathy for Maggy is no easy thing. Maggy is moody and spoiled; she breaks toys, wakes people in the middle of the night screaming, discourages homework, and generally causes chaos in the Austin household.
