termination of the sulphur reserves in the whole Gulf region with 
a view to defining the proper aid that these deposits should render 
to our sulphuric acid needs, not only during the war but afterwards 
as well. 
SUMMARY. 
Two sulphur deposits near the Gulf coast in Louisiana and Texas, 
worked by an ingenious and efficient mechanical process, not only 
are supplying practically all of the crude sulphur in this country, 
but their development has shifted the world’s largest sulphur indus- 
try from Sicily to the United States. The geological occurrence 
and method of working the Gulf deposits by means of the Frasch 
process are described in nontechnical language. The bearing of 
these deposits on the sulphuric acid situation is discussed and the 
need pointed out for a determination of the sulphur resources present 
in the whole Gulf region, with a view to defining a proper adjust- 
ment between the needs of the sulphur industry and the sulphuric 
acid industry.
