For many years a small book, FOGS AND CLOUDS by the same author, has occupied a unique position because it combined a simple-though thoroughly scientific-explanation of the various phenomena with a very complete collection of cloud photographs, finely reproduced. FOGS, CLOUDS, AND AVIATION again includes all this information (brought up to date) which is fascinating to the amateur as it is vital to the thousands who are teaching and studying meteorology for the benefit of aviation, commercial as well as military. In addition, the aviator find the significance of each type of fog and cloud noted-how thin, extensive, high and opaque they are, whether they provide fair or excellent one-way screens in combat, what the danger of icing is, etc. It is a distinct "Fog and Cloud" book, well rounded and detailed, not an unproportioned chapter from a general work on meteorology. It is indispensable to anyone interested in or dependent on sound interpretation of local weather signs and local weather forecasts.

When Gerda's beloved playmate, Kai, disappears one winter afternoon, all of the grownups give him up as forever lost. But Gerda knows in her heart that Kai can be rescued, and with nothing more than the clothes on her back, she journeys to a far country, populated by an ancient sorceress, friendly crows, and fearsome robbers. Gerda's power to face every obstacle in the quest to save her friend from his kidnapper, The Snow Queen, lies in her innocence and her abiding faith. Storyteller Hans Christian Andersen is famed for his heartwarming tales of enduring love and persistence in the face of adversity. Enchanting full-color images by Golden Age illustrator Edmund Dulac enhance Andersen's fairy tale of a girl's unshakable determination and stirring heroism, a classic that inspired the Disney animated film "Frozen."
