THIRD SURVEY. 



First Annual Report. 1890 323 10,000 



Geology of Ohio, Vol. VII. 



Part I. 1893 290 2,500 



Geology of Ohio, Vol. VII. 



Parts I. and II. 1894 C 990 7,500 



55 plates 

 Maps, plates of sections, etc., accompany many of the volumes. 



The disposition of the reports has been made almost exclu- 

 sively by the State Legislature, the members of each General 

 Assembly dividing among themselves for gratuitous distribution 

 the full edition of the volume or volumes of which they had 

 authorized the publication. Not the slightest reference was had 

 to the maintenance of complete sets of the reports. It is 

 scarcely credible that after such large outlays in publication, the 

 volumes should have been scattered in this reckless way. By 

 attention at the times of issue of the several volumes, those 

 specially interested were generally able to complete their sets. 

 Of the later volumes copies have been left on sale, at cost of 

 publication, in the hands of the Secretary of State. He is the 

 only State officer who is able to supply any of the volumes. 

 The reports find their way, however, to bookstores and, owing 

 to the increasing interest of the last few years, hundreds of sets 

 have been thus completed.
