The clean, crisp sparseness of Parnall's semi-abstract drawings almost disguises the unbecomingly arch tone, reinforced by the ""poetic"" word arrangement, of Baylor's ten rules for finding ""a/ special/rock/ that you find/ yourself/and keep/ and (sic) long as/ you can --/ maybe forever."" And given the validity of the basic observation -- if not everybody, then at least many children will recognize the satisfaction of carrying around a rock that feels ""easy in your hand"" and ""jumpy in your pocket when you run"" -- most will overlook such coy pseudoadvice as ""The worst thing you can do is go rock hunting when you are worried"" and ""A rock as big as an apple is too big. A rock as big as a horse is MUCH too big."" An attractive novelty, with a thin vein of truth.
