by James Dickey and William A. Bake. Oxmoor House, $50.00. Mr. Bake’s fine photographs range all around the southern mountains and as far west as Texas. The setting for Mr. Dickey’s charming text, in which a local resident explains the mountain way of life to a visitor, seems to be somewhere in North Carolina but is never definitely located. This vagueness is just as well, because if the spot—and the host—could be identified, they would be overrun by tourists.
