REPORT 



Geology. In pursuance of the plan for the completion of the 

 geological map of the State on the scale of 5 miles to i inch, areal 

 surveys have proceeded over several quadrangles. 



In the Adirondacks region the Russell quadrangle has been cov- 

 ered by Dr William J, Miller and a report rendered thereon. The 

 survey of the Lake Bonaparte quadrangle has been completed by 

 Dr A. F. Buddington. The work upon the survey of the Mount 

 Marcy and Ausable quadrangles has been concluded by Prof. James 

 F. Kemp, aided by Harold L. Ailing. The survey and mapping of 

 the West Point quadrangle undertaken especially as a means of 

 facilitating instruction in geology at the United States Military 

 Academy has been carried through by Dr Charles P. Berkey, super- 

 intending the field work of Marion Rice. The report on the geology 

 of the Gouverneur quadrangle by Prof. H. P. Gushing is completed. 



All the reports listed above are in condition for publication. 



Other geological activities have been a continuation of the ex- 

 amination and surveys of the postglacial deposits and drainage by Dr 

 James H. Stoller in the Saratoga region, Harold L. Ailing in Essex 

 county and John H. Gook in Albany county, while Prof. H. L. Fair- 

 child has been engaged with the special problem of the evolution of 

 the upper Susquelianna valley, a work which it is hoped to extend to 

 the entire course of the Susquehanna with the aid of the director of 

 the Geological Survey of Pennsylvania. 



Researches upon problems relating to the mineral industry which 

 have engaged attention have been connected with the origin and 

 composition of the salt deposits of the State, a work which has 

 entailed a large amount of analytical examination for the purpose 

 of acquiring more exact information regarding the potash and other 

 minor contents of these deposits. Much of this work has been 

 executed by Mr Ailing under the supervision of David H. New- 

 land, Assistant State Geologist. A restudy has also been made of 

 the iron ores of Orange and Putnam counties by R. J. Golony of 

 Columbia University. 



Paleontology. In the category of special problems, Mr Hart- 

 nagel has prosecuted further study of the Clinton formation and 

 fauna in central and western New York^ which has been productive 

 of interesting results both in paleontology and stratigraphy. 



Doctor Ruedemann has advanced his investigations of the Lor- 

 raine fauna of the Ordovician and has now completed a revision of 

 the formation and fauna in wihich are substantial additions to tlie
