Geology. 559 



Thus, for example, Germany, Bohemia, Denmark, Netherlands, 

 and Belgium, with an area of say 260,000 square miles, are to be 

 treated in one volume and one is also projected for the two 

 Americas and Antarctica, or say 17,000,000 square miles. It is 

 of course true that the geology of central Europe has been studied 

 in relatively great detail as compared with the larger part of the 

 Americas and that over wide areas the geology of the latter is 

 on a simpler and broader scale, yet to compress only a part of 

 what is known of this vast area into one volume will require so 

 sketchy a treatment that, as a source of information for regional 

 geology, its value can only be small, compared with the first 

 volume mentioned. It is to be hoped that as the work proceeds 

 this part may be enlarged and more contributors added, if it is to 

 have an international scope and use. 



The first sample of the work to appear now lies before us. It 

 is vol. 1, part 2, and covers Denmark. It is from the pen of 

 Prof. N. V. Ussing of Copenhagen. It is a masterly presenta- 

 tion of the subject and, in the 38 pages allotted, a remarkable 

 amount of detailed information is conveyed, relating to physiog- 

 raphy, stratigraphy, fossils, geological history, tectonics, resources 

 of economic value, etc. and a full bibliography. It is an excel- 

 lent model for the entire work. l. v. p.

1. United States Coast and Geodetic Survey. Report of the 

 Superintendent, O. H. Tittmann, showing the Progress of the 

 Work from July 1, 1908, to June 30, 1909. Pp. 184, with 4 

 appendices and 10 pocket maps. Washington, 1909. — This 

 report contains the usual statement of the work accomplished by 

 the Survey during the year ending June 30th, 1909. It is accom- 

 panied by four Appendixes giving Details of Field and Office 

 Operations (Nos. 1 and 2), also Results of Magnetic Observations 

 for the time named (No. 3), and further (No. 4), the Distribution 

 of Magnetic Declination in Alaska and adjacent regions for 1910. 

 This last Appendix, as also No. 3, is by R. L. Faris and is accom- 

 panied by a chart giving the lines of equal magnetic declination 

 and of equal annual change in Alaska for 1910. 



The Survey has also issued another volume of the results of the 

 observations at the permanent magnetic observatories ; this is for 

 the observatory at Sitka and covers the years 1905 and 1906. 

 This report has been prepared by Daniel L. Hazard, and is accom- 

 panied by thirty-six figures reproducing the magnetograms for 

 the principal magnetic storms.
