DIG A TUNNEL

From the tunnels of ants to the Chunnel connecting England with France, this lively tour of constructed tunnels highlights their variety as it explores their uses and manufacture. Hunter (Into the Sky, 1998, etc.) urges readers along, sprinkling a compact text with entertaining facts—“If you take a train from New York to Los Angeles, you’ll go through 65 mountain tunnels”—and asides. Miller’s cross-sectional illustrations are rendered with solid colors, long, straight lines, and sharp color boundaries, for an orderly, layered look that conveys plenty of activity without seeming cluttered. Younger fans of the wheeled vehicles that are visible here in profusion will want repeat readings. (Picture book/nonfiction. 5-7)
