This belongs in the series of game books that Hart is publishing, and some of the tricks included have appeared in previous volumes. But this is a whole book devoted to tricks, designed to be used by the 11 and 12 year olds, at which age tricks become very much a major factor, and on up into the early teens. Tricks with coins and bills, with checkers, with cards; tricks with tableware, with matchsticks, with numbers; parlor stunts; mind reading tricks; scientific oddities -- all presented in simple language with lots of diagrams and drawings. Surely popular.
