Grimsel Pass, Eggishorn, and Belalp—a circular tour around the great 
peaks of this group. Succeeding chapters describe the points of geologic 
interest from the Rhone valley to Bern by way of Kandersteg and Spiez 
and of the western portion of the range as far as Lake Geneva. In this 
itinerary the excursions have been planned for the pedestrian rather than 
the mountain climber, and by selecting various readily accessible view- 
points much of the wilds of the range can be studied without the labor and 
difficulties involved in penetrating into the heart of the mountains. 
The booklet is well illustrated with many profiles of structure, numerous 
photographs and sketches, and a map of the route. Being almost identical 
in size with Baedeker’s Switzerland, it fits readily into a coat pocket. At 
the end is a summary of the geologic literature bearing upon this portion 
of the Alpine chain. ReaneC 
Guide to the Geology and Paleontology of the Schoharie Valley in 
Eastern New York. By AmapEus W. GraBau. (New York 
State Museum, Bulletin No. 92, 1906.) Pp. 75-387, 24 plates, 
225 figures and geologic map. 
The Schoharie Valley is a classic locality in the history of American 
stratigraphic geology, since in it and Albany County the first systematic 
study of the Paleozoic rocks of New York was begun. In this valley, near 
Schoharie village, lived the Gebhards, father and son, who between 1820 
and 1835 worked out the succession of Silurian and Devonian strata in 
that region, collected fossils, and proposed stratigraphic names some of 
which, as, for example, Pentamerus and Tentaculite limestones, are still 
familiar to geologists. 
As the title indicates, this work is designed as a guide to the geology 
and paleontology of the Schoharie Valley for the use of students and 
others interested in its fine stratigraphic sections, for which it has long been 
famous. Naturally, therefore, the stratigraphy of the Schoharie region is 
minutely described, four chapters, comprising 150 pages of the Bulletin, 
being devoted to it. In these chapters the nineteen geological stages of 
that region, which range from the Lorraine of the Lower Silurian to the 
Catskill of the Upper Devonian, are fully described, together with the 
more characteristic fossils which are figured. 
Chapters 5 and 6 are devoted to a description of characteristic sections 
in the Schoharie region and the Helderbergs, and Dr. Grabau has not 
confined himself simply to the sections which he has studied, but has quoted 
freely from the works of former students. It should also be stated that
