Biologist Harrison has often used whimsical poetry to capture the imaginations of children interested in science. There's no poetry in this Earthworks picture book about caves, but Harrison's simple, fluid language is winning all the same. When Millicent the cow strays from the shade, Farmer Howe wonders what has drawn her away from familiar comforts. He discovers that underground breezes from caves beneath his pasture are keeping his cows cool. Then the science kicks in, as Harrison describes caves formation and the underground ecosystems that thrive in the cool dark. The picture, filled with surprising movement, nicely picture both the "story" and the science. An author's note and a bibliography of further readings are appended. It's science with grace, sure to please and inform.

VERY, VERY NICE AND INFORMATIVE!
