is in the improvement of the methods of manufacturing iron, and I have
been led to dwell upon the subject, perhaps even now longer than was in
good taste, carried away by my sense of the immense importance this
industry is to assume in our State, when our resources are properly investigated and brought into use.
SALT, OILS, CLAYS, ETC.
There are many other mineral staples found in our State, to which, did
time permit, I should be glad to call attention, citing the proofs we have
gained of their existence, their promise as regards quality and quantity,
and the investigations proposed for determining their abundance and
value. But I have already passed the limits I had assigned myself.
Within a few months a fuller report of our work will be published, and
in that report will be given the details of such matters as are referred to
now, as well as much information of interest in regard to some subjects
not here alluded to. I have, in the preceding pages, attempted nothing
more than an outline sketch of the duty assigned to the Geological
Corps, and what has been done toward its performance. In order that
this may be more clearly understood, I will very briefly recapitulate the
work accomplished by the survey during the last summer and fall, and
state what is our plan of operations for the future.
In many instances it has happened that the first season's work of a
Geological Survey has been mainly consumed in organization and preparation for the future. I think I have shown that we have accomplished
something more than this. In addition to our organization, we have
made a general, and, for the most part, thorough investigation of the
geological structure of the State; have studied each of the formations
found in our geological series, and have determined the relative position,
age, thickness and lithological characters of each; have settled the
doubts that have long hung over some of them; have added to the list
several not before known to exist here, and have marked the areas occupied by the surface exposures of each on a geological map. This map
has been made altogether from new and original observations, and may
be accepted as far more minute and accurate than any geological map of
Ohio before published.
More careful studies have been made of certain districts: as that of
the Straitsville coal field, by Prof. Andrews; of Greene and Montgomery
counties, by Prof. Orton; of Cuyahoga and Erie counties, by myself;
thus beginning the detail work of the survey, which it is proposed to
carry through all the counties and townships of the State. We have
also made a good beginning on our Economic Geology. Prof. Wormley,
our chemist, has made a large number of very carefully conducted
analyses of our coals, iron ores and limestones, earning many times over
