/Sands, by H. Ries and F. L. Gallup. Pp. xii, 259, with 30 plates 

 and 7 figures. Madison, Wis., 1906. — The geological and chemical 

 relations of the clays of Wisconsin were described in a Bulletin 

 of the State Survey by Dr. E. R. Buckley, issued in 1900. A 

 second part dealing with physical and other tests of the bricks 

 made from the clays was projected but not completed. The pres- 

 ent Bulletin by Dr. Ries takes up this latter aspect of the matter, 

 as well as dealing independently with the whole subject of the 

 clay industry. The observations upon which the report is based 

 have been accumulated by the writer with the assistance of Mr. 

 F. L. Gallup. It may be noted that the value of the products of 

 the clay-working industries of the State in 1905 was $1,382,000, 

 of which more than 90 per cent was in common brick. The 

 author discusses the probable future of the industry and concludes 

 that there is likely to be a steady increase in the annual produc- 

 tion of clay products and raw clays in the State. The second 

 part of the volume is devoted to a report on the molding sands 

 b5^ the two gentlemen already named. 



3. Geological Survey of Alabama. The Underground Water 

 Resources of Alabama / by Eugene A. Smith. Prepared in 

 cooperation with the United States Geological Survey. Pp. xvi, 

 388, with 30 plates and 23 figures. Montgomery, 1907 (The 

 Brown Printing Co). — The material of the present volume was 

 largely developed by work carried on jointty by the State Survey 

 and that of the general Government. Water Supply Papers Nos. 

 102 and 114 (U. S. G. S.) contain most of the well records here 

 given, as also a sketch map of the Artesian Water System. The 

 subject has been further investigated, however, and the results 

 are now published under the auspices of the Alabama Survey. 

 A somewhat full account of the geology of the State bearing 

 upon this subject is given, and the subject of Underground Waters 

 and Artesian Wells in general is also discussed. Then follows an 

 account by counties of the wells of the State, followed b}>- data 

 in regard to their chemical character. It is interesting to note that 

 of the 1414 wells described, 86 per cent are in the Cretaceous, 

 about 10 per cent in the Tertiary, and the remainder, 4 per cent, 

 in the older, forms of the Appalachian division. The larger part 

 of the wells are in the outcrop of the Selma chalk and obtain 

 their supply mainly from the Eutaw sands, although some pene- 

 trate as low as the Tuscaloosa, strata. A series of maps shows 

 the geological and geographical relations of these underground 

 waters. 



4. Geological Survey of Western Australia, Mt. Margaret 

 Goldfield ; by Chas. G. Gibson, Assistant Geologist. Bulletin 

 No. 24. 77 pp., 7 figs., 26 pis., with 13 geological and mining 

 maps. Perth, 1906 (Fred. Wm. Simpson, Government Printer). 

 — This report is the most recently issued of the series of special 

 bulletins dealing with the mineral fields of Western Australia. 

 The bed-rock throughout the region is granite, which occurs in 

 dikes and bosses, and greenstone, — both massive and foliated
