The latest of these maps to be published with accompanying de- 

 tailed account of the areal and structural geology are the Mount 

 Marcy and the West Point quadrangles, the former by Prof. James 

 F. Kemp, the latter by Dr Charles P. Berkey and Marion Rice. Both 

 are important as covering areas of special public interest, the one 

 embracing much of the area of the Tahawus region or the so-called 

 " Victory Park," the other including the location of the site and 

 vicinity of the United States Military Academy and which it is 

 believed will be helpful to its students in affording means of instruc- 

 tion in the application of geology to the arts of war. This map was 

 begun during the late war with this very end in view and as a part 

 of the activities of this State in connection with the National 

 Research Council's War Committee on Geology. This survey has 

 been very skilfully executed and constitutes an important addition 

 to the geology of the State, as the area covered is one of complex 

 structures difficult of resolution. 



Additional studies of the complicated Adirondack and the Highland 

 regions are in progress. A report on the Ausable quadrangle is 

 in press, and continuous investigations in route on the sedimentary 

 rocks of central New York and the Hudson valley. An effort is 

 being made to establish a reasonable subdivision of the Catskill 

 formation in the Catskill mountains and to determine if a division 

 of this massive into its Devonian and Carboniferous elements is 

 practicable. The factors and effects of glacial flow and postglacial 

 drainage over the southern tier of counties are engaging active 

 attention. 



In the industrial applications of the science constant contact 

 is maintained with all active operations and advice and counsel 

 given freely in a great variety of mining and quarry adventures. 

 The mineral industry of the State is not only highly varied but it 

 increases rapidly in variety. While its magnitude is impressive, 

 its variety is a more striking feature of the industry as a 

 whole. A very large capital is involved in the mineral production 

 and manufacture, and for the benefit of this industry as well as for 

 the general information of the public, the Museum has just issued a 

 comprehensive report entitled " The Mineral Industry of New York," 

 which is the first general treatise on this theme since the publication 

 of Lewis C. Beck's "Mineralogy of New York," issued in 1843. 

 This will serve as a statement of the present development of the 

 mining industry in this State and a succinct compendium of our 

 knowledge of the subject. Investigations also continue in speciaj
