GEOLOGICAL SURVEY OF OHIO. 15 
Bulletins 4 and 5 will be bound in one cover as they are upon coguate 
subjects, and Bulletin 5 is of itself too small to make a pe peate aly bound 
bulletin by itself. 
SEVENTH. THE CHEMICAL CHARACTER OF OHIO COALS AND NOTES ON THEIR 
PROPER UTILIZATION. 
This work was undertaken by Professor Nathaniel W. Lord, E. M., 
Consulting Chemist of the Survey, and Profesor of Metallurgy in the 
Ohio State University, who has done a great deal of important work along 
this line in other connections. The coal veins studied so far comprise 
the No. 4 or Clarion (Ferriferous limestone) coal of Vinton, Jackson, 
Gallia and Lawrence counties, and the No. 6 or Middle Kittanning coal, 
which was sampled with unprecedented care at frequent intervals over its 
whole area between Athens and Tuscarawas counties. There yet remains 
the extreme northern and southern extensions of the No. 6 coal to be 
sampled, but the work now done covers the main productive area. These 
researches are directed towards establishing the chemical unity of real 
coal-matter of any particular vein, as distinguished from its accidental 
or accessory ash-forming ingredients, and also the sharp distinction be- 
tween the real coal-matter of different veins, as evidenced by the com- 
position, calorific power, etc. His work also includes a study of the oc- 
currence of sulphur in coals, and to what extent it may be reduced by 
treatment. | 
Preliminary reports on part of this work have been published, by 
permission, in the engineering press. It is expected that a considerable 
portion of the report will be printed in the near future, but the completion 
of the work for all the coals of the state is a distant matter. 
EIGHTH. THE SALT INDUSTRY OF OHIO. 
This subject was taken up by Assistant Geologist Bownocker during 
the summer of 1903. ‘The discovery and utilization of the rock salts of 
northern Ohio has all been subsequent to the report by W. J. Root in 1888, 
and the development of a growing soda ash industry on this foundation is 
the immediate occasion for taking it up at this time. Ohio with her ‘stores 
of lime, sand and fuel, has only needed soda to become a great center of 
the glass industry. This supply has now become a possibility. The report 
on this topic is complete and ready for printing and will appear shortly as 
Bulletin 8. 
NINTH. THE PITTSBURGH COAL IN HARRISON, AND THE MEIGS CREEK COAL IN 
HARRISON, JEFFERSON AND BELMONT COUNTIES. 
Alinost the only coal areas left unmapped in the work of the previous 
survey are those veins found in the high broken land of southeastern 
Ohio. The recent sudden increase in interest in the thin veins of coal 
away from present railroad communication has led to a very considerable
