As monitor of the seasons, the author writes of world and weather in Washington in the Spring of 1945. A naturalist's diary, of the many, often dramatic manifestations of the change of the year. The migrant birds, the nuances of the weather, the exploratory trips to shore, river, basin and creek, the joyous discoveries, the exceptional qualities that marked the transitions -- these capture the passing moments with clarity and intense delight. Caught ""when the government wasn't looking"" they have the feel of confinement escaped, of routine lost, and take stock of much that ordinary eyes and interests miss. Detailed observation is enhanced by the perfection of Francis Lee Jaques illustrations and the whole is, in its many digressions and often wry commentary, an outdoor book of special value.
