mapped in the region from Newburg southwest to Monroe, and 

 some of the Paleozoic boundaries were retraced on the newly 

 issued topographic atlas sheet covering that region. Several 

 outcrops of crystalline limestone, occurring in ,the Highlands 

 between Central Valley and Fort Montgomery, were critically 

 examined, and it was decided that, in place of the pre-Cambrian 

 age usually assigned to them, they were probably Paleozoic, 

 being underlain by a quartzite corresponding to the Cambrian 

 quartzite of Dutchess, Putnam and Westchester counties. Late 

 in November, field work in the northwestern part of Putnam 

 county confirmed these views, similar highly crystalline lime- 

 stone being found in similar association with quartzite. 



During the greater part of the winter and sprang, Mr Eckel 

 was employed in cooperation with a draftsman on the compila- 

 tion and drafting of the new edition of the geologic map of the 

 State. Several short trips were made by him in April, May and 

 June for the purpose of verifying previous work in the western 

 part of the State. 



During the remainder of the fiscal year he was employed in 

 work on the metamorphic rocks of southeastern New York and 

 western Connecticut, part of this time being spent with the 

 state geologist in the field conference mentioned below. 



In September a field conference was held by the state geologist 

 with Professor Van Hise of the United States Geological Sur- 

 vey, which extended from New York city and Westchester 

 county, N. Y., into western Connecticut and northwestern Massa- 

 chusetts. The consequence of this conference was that the 

 work in the region about New York city, which had been carried 

 on by the writer for many years, and of which the results are to 

 be published in cooperation with the United States Geological 

 Survey, was found to be entirely correct. The New York 

 classification is accepted and will be extended into Connecticut 

 and Massachusetts. One technical question raised by Professor 

 Van Hise could not be decided in New York, and in consequence 

 it seemed necessary for Mr Eckel to make some visits to south- 

 western Connecticut in search of further evidence. The ob-
