PREFACE. XI 



remain in the hands of the members of the Legislature, State officers, and the Geo- 

 logical Corps, which can not be supplied. 



The history of the publication of Volume II. of our Final Report, now given to 

 the public, is in many respects similar to that of the first. It was submitted to the 

 Legislature at its last session, and was then ordered to be printed in an edition of 

 twenty thousand copies. An appropriation of $60,000 was made to cover the cost of 

 such publication, a sum which, owing to a considerable reduction in the cost of pub- 

 lication during the past year, and a very careful economy on the part of those who 

 have had charge of the expenditure, has proved sufficient for the purpose. An effort 

 was also made by the Legislature to secure the publication of this volume in a style 

 fully equal to that of Part II. of Volume I. This was done by authorizing the Sec- 

 retary of State to have paper of the requisite size and quality manufactured expressly 

 for the geological report. It unfortunately happened, however, that the paper sup- 

 plied on the contract proved inferior to the samples offered when the contract was 

 awarded, and it was consequently rejected. 



The alternative now presented itself of a delay of several months, or the use of in- 

 ferior paper then in the hands of the Secretary of State. The latter was chosen, and 

 consequently Part I. of Volume II. is printed in the same style as the correspond- 

 ing part of Volume I., while larger and better paper was supplied for Part II., making 

 this to correspond with Part II. of Volume I. The result of these accidents has been 

 that we have two volumes on Geology in which the page is smaller and the paper 

 lighter than was desirable, and yet the cost has thereby been considerably reduced. 

 At the same time we have two volumes on Palaeontology in which the page is 

 larger — necessitated by the size of the plates — and the paper is of better quality. 

 This want of uniformity in the entire series of volumes will be generally deplored, 

 but it has been inevitable in the circumstances of their publication. 



In framing the original plan for the Final Report of the Geological Survey, it was 

 supposed that all the matter descriptive of the general and local geology of the State 

 could be included in two volumes devoted to Geology ; but when the detailed reports 

 on all the eighty-eight counties we were specifically required to examine and describe 

 were completed, it was found that abundant matter had been supplied for three vol- 

 umes. A third volume on Geology has, therefore, been prepared, and now awaits the 

 action of the Legislature. This volume includes reports on the following counties : 



Of the First District — Ashland, Belmont (north half), Carroll, Columbiana, Coshoc 

 ton, Guernsey (north half), Harrison, Holmes, Huron, Jefferson, Knox, Licking, 

 Mahoning, Medina, Muskingum (north half), Portage, Richland, Stark, Tuscarawas, 

 Wayne.
