3. A Catalogue of the Cretaceous and Tertiary plants of North 

 America; by F. H. Knowlton, pp. 1-247, 1898, IT. S. Geological 

 Survey, Bulletin 152. — Mr. Knowlton has furnished paleobotan- 

 ists a valuable aid to study by publishing this working catalogue 

 of the known American species of Cretaceous and Tertiary plants, 

 without waiting to make it absolutely perfect. Systematic names 

 are checked back as far as the Kew Index for genera found also 

 living, and to original source of description for species and the 

 more important references to later descriptions or illustrations. 

 Also the matters of geographical distribution and geological 

 range are given so far as commonly reported in the literature, 

 while the full knowledge regarding these points is left for future 

 investigation. The Bibliography is a list of the papers consulted 

 without assuming that it is a complete list.

 panying papers. Samuel Calvin, State Geologist, vol. viii, pp. 

 1-427, plates 1-xxxii, figures 1-13, and six maps, 1898. — Thi& 

 eighth volume contains detailed reports of the areal geology and, 

 where ascertained, the faunal lists of fossil species for the counties 

 of Dallas, Delaware, Buchanan, Decatur and Plymouth, with 

 excellent colored maps and frequent half-tone views of important 

 rock sections and landscapes. H. F. Bain contributes a chapter 

 on Properties and Tests of Iowa Building stones. h. s. w. 



5. A Preliminary Report on a Part of the Gold Deposits of 

 Georgia; by W. S. Yeates, State Geologist, and S. W. McCallie 

 and Francis P. King, Assistant Geologists. 1896. Geological 

 Survey of Georgia, W. S. Yeates, State Geologist. Bnlletin No. 

 4-A. — This handsome and well illustrated volume of 542 pages 

 gives an account of the various gold deposits of Georgia, espe- 

 cially with reference to their present development. As is well 

 known, these lie chiefly on lines running northeast and southwest, 

 in the northern part of the State. Some fifty years since, the 

 amount of gold annually coined at the State mint amounted to 

 nearly or quite $500,000 ; but since the exhaustion of the placer 

 mines, from which most of the gold had been derived, the output 

 has fallen off very largely, and in 1895 the total production ot
