MACHINES AT WORK

Using the bold, black bordered forms and simple colors familiar to readers of his other popular books, Barton introduces seven pieces of heavy machinery in action (plus people with drills and pickaxes) with a brief, imperative text ("Knock down that building. Bulldoze that tree. . .Dump that rubble"). Except where the verbs give a clue, the adult who shares the book is left to supply the names for the equipment. The very simple images here make the book appropriate to the youngest; its directness is likely to inspire spontaneous dramatic play.
