PREFACE. 
By PROF. EDWARD ORTON, Jr., STATE GEOLOGIST. 
‘THE ORGANIZATION AND WORK OF THE GEOLOGICAL SURVEY 
OF OHIO. 
In issuing this volume, the first of a new series, it 1s proper and 
seasonable to set forth the relation of the work here presented with that 
which has been done by the organization in previous years, and to state 
what plans for the future are now being entertained. 
~ HISTORICAL. 
The last work done by the survey under the administration of Dr. 
Edward Orton, was embodied in Volume VII, published in 1893. In that 
volume, the preface, amounting to 11 pages, was devoted to a historical 
review of the work accomplished up to that time by the First, Second and 
Third organizations of the Geological Survey of Ohio. It is there shown 
that in Volume VII, the last outstanding tasks were completed, the last 
unpublished manuscript collected, the promises made during preceding 
administrations fulfilled, and that the volume thus brought to a natural 
conclusion the work which had been carried on for so many years. 
During the succeeding six years, the work of the survey stood in 
abeyance. Dr. Orton still held the appointment of State Geologist, but 
the position was largely honorary as no appropriations were made to sup- 
port the office in any way. Correspondence involving geological ques- 
tions was answered and occasional visits were made to different points 
to give advice regarding local geological problems, but this work was done 
voluntarily and at private expense. 
Dr. Orton’s death occurred on October 16th, 1899, and Governor 
Bushnell appointed the present incumbent on December 4th, 1809, to fill 
out the unexpired term, which terminated April 22nd, 1901. At this time 
Governor Nash appointed the present incumbent for the term ending 
April 22nd, 1904, and later Governor Herrick reappointed him for the 
term ending April 22nd, 1907. 
THE LEGAL STATUS OF THE SURVEY. 
The law under which the last .work of the Third organization was 
performed was passed in 1889. For the information of the public, it is pub- 
lished in full:
