Wisconsin stage. Two systems of well-marked moraines are 

 shown. As a study of simple glaciation and of water conditions 

 this folio occupies a unique place. 



Bulletin No. 217. Notes on the Geology of Southwestern 

 Idaho and Southeastern Oregon; by Israel C. Russell. 80 pp., 

 18 pis., 2 figs. 



Taken in connection with Bulletin No. 199 and Water Supply 

 Paper No. 78, the publication of Professor Russell's recent work 

 gives a fairly complete account of the general geological rela- 

 tions of the interesting Idaho-Oregon arid region. Malheur 

 Lake (a water body 135 square miles in area and less than 10 ft. 

 deep !) is not a remnant of a larger lake but is caused by a lava 

 dam. The volcanic phenomena of this region is particularly 

 interesting. Details of structure, of character of flows, cones, 

 bombs, are described and illustrated. Many of the bombs were 

 not formed by rotation in air. Besides the recent volcanics, Ter- 

 tiary lake beds and lavas occur in this area.

2. New York State Museum, F. J. H. Merrill, Director, has 

 recently issued the following publications : 



Bulletin No. 66. Index to Publications of the New York 

 State Natural History Survey and the New York State Museum; 

 by Mart Ellis ; pp. 239-653. An Index has been made to the 

 publications of the New York Survey and related scientific 

 organizations covering the years 1837-1902. The arrangement 

 gives : a list of publications ; author index ; subject index ; index 

 to descriptions of fossils. This bulletin renders readily accessible 

 the scientific data distributed in an apparently haphazard way 

 through various New York reports.

 ration and watershed. This map, drawn on a scale of 12 miles to

 in schools. 



3. Geology of Worcester, Mass. ; by Joseph H. Perry and 

 B. K. Emerson. 159 pp., fully illustrated. Published by the 

 Worcester Natural History Society. — Mr. Perry has for several 

 years been assisting Prof. Emerson in mapping the metamorphic 

 rocks of Worcester County under the direction of the U. S. Geo- 

 logical Survey and has now published part of the results of this 

 work. Because of the nature of the region, mineralogical and 

 petrographical descriptions constitute the greater part of the 

 book. Geologists will be interested in the descriptions and excel- 

 lent illustrations of Lepidodendron acuminatum, the only fossil 

 yet found over a wide area in Massachusetts and Connecticut. 

 The occurrence of this fossil shows the Worcester phyllite to be
