the bay (the latter probably Point St. Bernard on the map of the 

 work here noticed) the fossils were found " quite thickly dis- 

 tributed" in one of the layers, " 15 to 20 occurring in a slab a 

 foot square" (p. 604). The coast had many deep coves and long 

 points, so that the one excursion was prolonged unintentionally, 

 and somewhat imprudently considering the savage climate and 

 people of the region, to twenty-four hours, the best place under 

 some bushes being selected for the night. But no more fossils 

 were found.

5. The American Geologist. — The prospectus of an American 

 geological monthly has been recently issued, announcing the 

 appearance of the first number on the first of January. Its aim 

 will be to cover all branches of the science in its publication of 

 papers and notices of discoveries, and also to afford special aid, 

 by suggestion and information, to the teacher in geology. The 

 editors and publishers for the coming year are as follows: Profes- 

 sor S. Calvin of Iowa, Professor E. W. Claypole, of Ohio, Dr. 

 Persifor Frazer of Philadelphia, Professor L. E. Hicks of Ne- 

 braska, Mr. E. O. Ulrich of Kentucky, Dr. A. Winchell of Michi- 

 gan and Professor N. H. Winchell of Minneapolis. The Journal 

 will be published at Minneapolis, in monthly numbers of at least 

 fifty-six octavo pages each, at three dollars a year. There is no 

 lack of good material from home investigation for the American 

 Geologist. It promises to be of great service to the science and 

 the country. 



6. Geology and Mining Industry of Leadville, Colorado; by 

 S. F. Emmons. 750 pp. 4to, with a folio Atlas and numerous 

 plates. — United States Geological Survey, Clarence King, Di- 

 rector. Washington, 1886. — This report of Mr. Emmons gives a 

 full account of the Leadville region, as regards its geology, its 

 mineral veins and their products, its mines and its mining indus- 

 try, and discusses ably the origin or genesis of the veins of ore. 

 The illustrations accompanying the text represent scenery, the 

 microscopic structure of the rocks, furnaces, implements for as- 

 saying and smelting, and various other matters connected with 

 the mining operations. The Atlas contains maps with contour 

 lines of Central Colorado and of the Leadville mining region, and 

 others giving in color the topographical geology, besides numer- 

 ous geological sections. The work is grandly prepared in all 

 respects and is a very important contribution to geology and the 

 science of mines and mining.
