E. MINERALOGY AND GEOLOGY. 207 



$13,900. In 18V0 an appropriation of $18,000 was made, and 

 in 1871 one of $21,000. The appropriations for subsequent 

 years have been already mentioned in our pages. 



The cost of the survey to the state has been somewhat 

 unnecessarily increased by the publication of an excessive 

 number of copies of the report; as, while the chief geologist 

 estimated that 5000 copies would be sufficient for the needs 

 of the state, and to supply outside institutions and individu- 

 als, 20,000 were actually printed; this involving not merely 

 a great expense for press- work and paper, but also, for the 

 numerous plates accompanying the reports. The responsi- 

 bility of this excessive number, however, rests upon the Leg- 

 islature, and not on the geological corps. 



Still the resources of the state are sufficiently ample to 

 meet such expenditures, while the increased number will in- 

 sure the supply to very many more intelligent recipients. It 

 is to be hoped, however, that the appropriations for the con- 

 tinuation of the remaining volumes of the report will not in 

 any way be interfered with by the excess of the first order. 



Professor IsTewberry renders proper acknowledgments to 

 various persons, both savants and others, who have aided 

 him in his work. 



The volume, which constitutes "Part One" of the report, 

 contains a valuable sketch of the physical geography of Ohio, 

 with a statement of its geological relation to the Silurian 

 and Devonian system, and also an account of the geology of 

 Cuyahoga and Summit counties, all by the chief geologist, 

 and constituting about one third of the volume. Professor 

 E.B.Andrews follows with a history of Gallia, Meigs, Athens, 

 Morgan, and Muskingum counties; Mr. Edward Orton,with 

 that of the Cincinnati group Hamilton, Clermont, and Clarke 

 counties ; the remaining counties being reported upon by Mr. 

 M. C. Pvead, Mr. G. K. Gilbert, and Mr. N. H. Winchell. 



CALIFORNIA PETEOLEU:^. 



Professor Peckham has recently communicated an elabo- 

 rate paper to the A^nerican Chemist upon the asphaltum of 

 California, in which he takes occasion to refute the idea that 

 the California bitumen dej^osits in any respect represent the 

 oil springs of the East. He remarks that bitumen occurs 

 there of every variety, from green petroleum, of the consist-
