Simple text and photographs present the digging of a tunnel, including information on the workers and equipment needed.
Limited vocabulary accompanies full-page color photos that show, in brief terms, the processes described in these titles. Two sentences per page serve as the caption for the facing photo. Demolition indicates that sinks, doors, and windows are the only things salvaged from a building before it is destroyed. The book does not use the term "implode" when discussing the use of dynamite to destroy tall buildings. Tunnels makes no mention of the Chunnel, compares a tunnel to a mine, and implies that coal and gold are the only ores that are mined in them. Readers will likely misinterpret the word "clay" when the text discusses using clay or concrete on the sides of an excavation to "hold the soil in place." Both titles end abruptly. Strictly marginal buys.-Eldon Younce, Harper Elementary School, KS
