An interim report on the moon which tends to date itself in the very attempt to be up-to-date. Swiftly surveying ancient beliefs and the early growth of scientific knowledge, the author passes on to description of the moon's characteristics, and encounters difficulties. Despite the inclusion of information about and photographs from the Surveyor I mission (May, 1966), all of the assembled evidence seems to have come from earlier observations at long range. At every step, he attempts to avoid outright misstatement by suggesting alternative possibilities, but the value of purchasing a speculative survey of a subject undergoing extensive reappraisal is questionable. The concluding section, a summary of space travel accomplished and projected, adds nothing to very little.
