In first book format, an orientation for urbanites of any age, from the child enthralled by tractors to his older brother assigned to dairy farming to their perspiring parents (what does a smudge pot do, what happens in a silo). Some of the information is rather rudimentary (""cows and horses usually produce only one baby at a time"") and much of it is aimed--directly--at the passing motorist (how to identify a farm by its outbuildings), but for children who don't get closer than the family car it provides a vicarious visit to different types of farms, checks on each through the seasons, considers the changing nature of farm life generally, and concludes (almost the whole second half) with a glossary of old and new equipment. Some of the old tools are not illustrated (or if illustrated, are not labeled), but there's a good-sized photo of each of the new machines at work. A quick look at the rest of the world puts the American scene in perspective, and suggests that problems are not the same everywhere. Farming without statistics or sentimentality, which gives it an edge over most of its competitors; fine as far as it goes.
