KIRKUS REVIEW

 In the Venture series, a discussion of scientific dating, including the study of tree rings, strata, varves, carbon remains, thermoluminescence, space rocks, and radioactivity. Using a clear, readable style and helpful drawings, Smith is most successful at presenting earlier methods. But when it comes to methods employing radioactivity, his descriptions are too brief to be very informative--e.g., ``This very difficult method [thermoluminescent dating] has given some useful results in dating pottery, bones, teeth, and volcanic ash that is relatively young, geologically speaking.'' Why difficult? How young is young? In generalizing about complex topics, it's especially important to list sources. None are given here; moreover, though geological dating is a rapidly changing field, more than half the titles listed for ``Further Reading'' are 20 years old or more. A book that attempts too much and falls short. Glossary; index. (Nonfiction. 12-14)
