 the administrative report and index, the following papers : A

5. The Badland Formations of the Black Hills Region ; by 

 Cleophas C. O'Habra. 144 pp., 50 pis., 20 figs. South Dakota 

 School of Mines, Bulletin No. 9, Department of Geology. Rapid 

 City, South Dakota, November, 1910. — The "badlands" of South 

 Dakota form one of the most interesting physiographic sub- 

 provinces in the world, and taken in connection with the Black 

 Hills, forms a type area which in many respects is unique. While 

 the structure and stratigraphy are not complicated, yet the details 

 are so important as to fully justify the prominent place given to 

 this area in the literature. Heretofore students have had to 

 search through widely scattered technical reports in order to 

 obtain information regarding the origin and topographic develop- 

 ment of the badlands, as well as of the large and interesting col- 

 lection of fossils. Thanks to Professor O'Harra, we now have a 

 single volume accessible to students and amateurs wishing to 

 become acquainted with this country, — a volume which does not 

 require advanced scientific training to understand. From an 

 educational standpoint the publication is, therefore, abundantly 

 justified in spite of the absence of essential facts and interpreta- 

 tions new to science. 



6. West Virginia Geological /Survey, I. C. White, State 

 Geologist. Bulletin 2. Pp. 358. Morgautown, 1911. — Follow- 

 ing Bulletin No. 1, which gives a bibliography of the state, the 

 West Virginia Survey has now issued a volume containing tables 

 of levels and distances, and also coal and coke analyses. The 

 levels are compiled from records of the State and Federal Sur- 

 veys, and have been supplemented by data collected by the vari- 

 ous West Virginia railways. The analytical tables contain 

 results of tests of coal made from all the economic horizons of 

 importance, — namely, the Pottsville, Kanawha, Allegheny, Cone- 

 maugh, Monongahela, and Dunkard series. The estimated coal 

 production for 1910 is Go, 000,000 short tons. h. e. g. 



7. New Zealand Geological Survey, J. M. Bell, Director. 

 Bulletin No. 9 (New Series), The Geology of the Whatatutu 

 Subdivision, Raukumara Division, Poverty Bay ; by James 

 Henry Adams, 1910. Pp. iii and 40, 3 ills., 5 maps. — In age 

 the rocks included within this subdivision are upper Miocene and 

 consist of shales, argillites, sandstones, with coarse sandstones 

 and conglomerates in the upper portion. Pumiceous deposits, 

 possibly of Pliocene age, also occur. An interesting problem is 

 presented by the fact that many of the igneous pebbles in the 

 conglomerate are unlike any rocks thus far discovered in the
