 Art. 

 Dr. John B. Rinaldo from Assistant Cura- 

 tor in Archaeology to Associate Curator 

 of Archaeology. 

 Dr. Louis 0. Williams from Associate Cu- 

 rator of Central American Botany to 

 Curator of Central American Botany. 

 Dr. Edward Olsen from Associate Curator 

 of Mineralogy to Curator of Miner- 

 alogy. 



Lectures Given 



The ancient beaches of Lake Chicago 

 were studied last month by a group from 

 the Chicago Academy of Sciences in a 

 tour led by Harry Changnon, Geology 

 Curator of Exhibits. 



Eugene S. Richardson, Jr., Curator of 

 Fossil Invertebrates, spoke on "Paleo- 

 zoic Fossils of the Chicago Area" at the 

 Chicago Academy of Sciences during 

 November. 



C. Earle Smith, Jr., Associate Curator 

 of Vascular Plants, discussed plant cir- 

 culation on the "Science in Motion" 

 Educational Radio Series presented by 

 Radio Station WBEZ (FM) last month. 

 The program was later rebroadcasted 

 by Radio Station WIND. 



Rainer J^angerl, Curator of Fossil Rep- 

 tiles, lectured this fall before the Rock- 

 well Literary Society, Rockwell Women's 

 Club, on the Mecca project — a pioneer- 

 ing undertaking in systematic research 

 in which Dr. Zangerl plans to recon- 

 struct exactly what existed in one Indi- 

 ana county during a particular four-year 

 period, 250 million years ago. The lec- 

 ture was one in a series that has been 

 scheduled by the women's club on the 

 history of Parke County. 



Television Participation 



Maryl Andre of the Raymond Foun- 

 dation will appear on Lee Phillip's 

 "Friendship Show" (CBS-TV, Chan- 

 nel 2, 8:30 a.m.) on Saturday, January 7 

 to present a special program on "animal 

 tracks." The "Friendship Show" is a 

 children's production that has enjoyed 

 popularity for a number of years on CBS.

The Story oj Geology, by Jerome Wyckoff. 

 Golden Press, New York. 177 pages. 

 $4.95. 



The Story oj Geology is a stimulating de- 

 parture from the treatment of elementary 

 geology which has become more or less 

 standard over the last twenty years. In 

 the past, the approach to the subject has 

 been largely paleontological and tended 

 to emphasize the exotic and extraordi- 

 nary in an effort to capture the imagina- 

 tion of younger minds. One is often left 

 with the impression that the greatest 

 part of the earth's history is dominated 

 by the "terrible lizards" of the Mesozoic. 



In this book the approach is strongly 

 oriented toward physical geology, and 

 deals with the day-to-day processes that 

 have acted to form the earth over the 

 past five billion years : the action of sur- 

 face and ground waters, the action of ice 

 and wind, the effects of changes in land 

 elevation and sea level, volcanism, sedi- 

 mentation, and the formation of meta- 

 morphic rocks. In addition, the author 

 covers the larger problems of the internal 

 structure of the earth, the formation of 

 continents, and the structure of ocean 

 basins. 



In itself, this treatment is not unique, 

 since it may be found in all texts of ele- 

 mentary physical geology. However, in 

 concise terms the author also presents 

 the evidence upon which the conclusions 

 are based. For example, he points out 

 what earthquakes are, how they are de- 

 tected, and how they are located. He 

 diagrammatically shows the principle 

 upon which a seismograph is built and 

 what it measures. In writing such a 

 book the author could easily have drawn 

 from current textbooks. However, one 

 finds almost startling references to geol- 

 ogic processes and research results that 

 are currently being discussed in ad- 

 vanced texts and technical journals. As 



examples: he treats of chemical diffu- 

 sion as a process in the formation of 

 metamorphic rocks; he notes that granite 

 may form metamorphically as well as by 

 igneous activity; he discusses the evi- 

 dence for continental drift and the mi- 

 gration of the earth's poles; and most 

 surprising of all, he discusses Project 

 Mohole, the plan now being considered 

 to drill 25 miles down to the beginning 

 of the earth's mantle. 



It must be emphasized that this book 

 is not a textbook of geology; it is what 

 the title implies, a story of the geology of 

 the earth. The book is profusely illus- 

 trated with about 160 excellent color 

 and black and white photographs and 

 about 90 color drawings. 



Quarrying g: 



The Story oi Geology" 



Although written for the younger teen- 

 age reader, this book is heartily recom- 

 mended for the adult of any age who has 

 ever been curious about the earth on 

 which he lives. 



Edward J. Olsen 

 Curator of Mineralogy
