Product Description Introduces readers to dams, their purposes, and how they may be built From School Library Journal KGr 2Illustrated with attractive, colorful photographs, these books offer short, simple introductions to their respective subjects. The brief texts (two or three sentences per page) explain the specific functions of each type of structure mentioned. Canals presents a nice array of examples ranging from the canals of Venice to the Erie Canal and offers a simple yet clear explanation of how locks work by using an analogy of toys that float in a bathtub or a wading pool. Towers is the least successful of the three, for the word is never defined or explained, and examples include church steeples, a silo, a windmill, and the Washington Monument. Organization is unfocused, and some of the text is irrelevant ('The cows eat after they are milked'). On one occasion, pictures and text don't agree, and the questions are condescending. All three titles have threepage photo indexes that give a few additional facts about the canals, dams, or towers depicted. The bright, informative photos are the strength of these series entries.Katherine Borchert, Arlington Central Library, VACopyright 1997 Cahners Business Information, Inc.
