 and others) in charge of the Ward Natural Science Establishment 

 at Rochester. 



This much divided and scattered condition of the work is pro- 

 foundly embarrassing and involves serious loss in concentration of 

 effort and of time and enjoins arduous and exacting conditions. 

 Yet it may be regarded as making for progress, as it certainly is 

 now unavoidable in preparing for the equipment of a new museum. 



This situation has not been allowed to interfere with the progress 

 of the proper scientific investigations of this division, which have 

 taken the direction indicated herewith.

GEOLOGICAL SURVEY 



Areal geology 



In the progress of the survey directed toward the execution of 

 the geological map of the State on the topographic scale of i mile 

 to i inch, a considerable number of topographic quadrangles have 

 been completed and published, with full explanatory details of 

 geological structure. In addition to the completed quadrangles 

 a variety of special maps have been issued in connection with par- 

 ticular geological problems, some of the older of these maps being 

 on such geographic base of approximate accuracy as was best 

 available, but all special maps of later years, whether they have 

 covered limited areas, completed county areas or a series of coun- 

 ties, have been based on the topographic unit. 



A list of all geologic maps of the State, of every description, 

 was published in my report of last year, and the number was there 

 shown to be large, 329 entries being recorded. I append here a 

 list designed to indicate only the complete quadrangle maps which 

 have been made with special reference to the systematic execution 

 of the State map. In this list the terms starred indicate maps now 

 in press.
