Enchanting small-boy adventures -- a grammar school Odyssey. Henry Huggins, third grade man, is a neighborhood immutable -- the boy with the limp mongrel, the boy whose parents feel compelled to root out night crawlers by flashlight so their son's business obligations might be fulfilled, the boy who winces and slides down in his seat when parts for the school's dramatic productions are assigned. Mrs. Cleary must have had her ear to the door many times to catch the flavor of third grade manners and mores. Young readers will sympathize with Henry's horror at the loss of prestige involved in being required to play the part of Little Boy and be kissed by a dumb eight-grade girl on the stage; Henry's determination in sheltering the rapidly spawning progeny of two buzy guppies; and the gloomy tragedy when the original owner of Henry's dog, Ribsy, appears triumphantly on the scene. A collection of light, gay episodes, sure to please.
