The elusives of the stone circle near Salisbury are suggested in this sharp, self-contained approach. Possibilities of transport--overland for the outer ring, by raft (at least 250 miles) for the smaller ""bluestones""--are elaborated with a diagram illustrating how the spanning lintels could have been raised to the height of the uprights. Carbon 14 dating suggests 1800 B.C. as the start of construction that must have lasted 300 years. Finally, theories of its general purposes--Hawkins' sun calendar, religious worship--are suggested but not examined for significance. The Ambrus illustrations--brown on black with an occasional sun or sliver of moon--are at once expressive and precise. None of the other circles in the British Isles are mentioned but there is more than enough here to engage a youngster's imagination. The first full juvenile on the subject, and a very strong draw.
