Salt Deposits of Northeastern Ohio — Bownocker. 371 
salt that in 1890 the state produced only two and six-tenths 
per cent of the total yield of the United States, ranking 
sixth among the states. Less than ten years earlier Ohio 
produced over six per cent of the total and was surpassecf 
by New York and Michigan only. 
Sa/i Discovered in Northeastern Ohio. About 1886 
when it seemed that Ohio must cease to be a large salt pro- 
ducer, an important discovery was made. In drilling for 
natural gas at Newburg, near Cleveland, rock-salt was 
found. This well was the deepest that had been drilled up 
to that time in northeastern Ohio, and furnished valuable 
data on the stratigraphical succession of that part of the 
state.
