KEPOKT OF THE DIRECTOR IQIO 



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 counties, 

 have been based on the topographic unit. 



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

 issued officially or privately, was published in my report for 1908, 

 and the number was there shown to be large, 329 entries being 

 recorded. At least ten items may be added to this number at the 

 present date. 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:
