an undue haste. With the completion of the quadrangles named 

 the list of geologic maps now produced on this scale will be as 

 here given, this list including smaller special maps of parts of 

 quadrangles. The accompanying map also indicates the condition 

 of this work. It is hardly necessary to observe that this list and 

 map must not be taken as indicating only that portion of the area 

 of the State that has been geologically mapped. The public is 

 familiar with the fact that this office has issued at various times 

 in its history maps of the entire area of the State on various scales 

 from 5 miles to the inch down and also a very large «number of 

 smaller maps of special localities, but all these were plotted on an 

 imperfect geographic base and are to be regarded as only in the 

 line of progress toward the exact results recorded on the greater 

 topographic maps.

In the progress of the surveys of the past year problems of 

 special interest have arisen, some of local importance, others of 

 a wider import. Some of these are here indicated with their 

 probable solutions. 



Rochester and Ontario Beach quadrangles. The work in this 

 area has been in charge of C. A. Hartnagel and although the geo- 

 logic structure of the region has been so well known that
