sulphur deposits may itself, under proper conditions, 
form such deposits. This gas, although not affected by 
oxygen when dry is, under moist conditions, or in the 
presence of water containing oxygen in solution slowly 
oxidized, forming sulphur and water. 
In view of these facts, it seems probable that the sul¬ 
phur mass found at Floral City was formed by the decom¬ 
position of hydrogen sulphide gas slowly escaping from 
the underground waters, the reaction taking place in the 
presence of a limited supply of oxygen. 
While only a small quantity of sulphur has been found 
in Florida, if the above suggestion as to the origin is 
correct, the presence of this mineral in workable quanti¬ 
ties is not impossible and is indeed even probable. 
MINERAL WATERS. 
The springs of Florida are famous for their volume of 
flow as well as for the clearness and beauty of their water 
and the beautiful scenery about them. Many of these 
springs are used as health resorts. The United States 
Geological Survey volume on Mineral Resources reports 
the sale of mineral waters in Florida for 1907 as 43,430 
gallons, valued at $12,378. 
The areas in which flowing artesian wells are obtained 
are indicated on the map which accompanies Bulletin No. 
1 of the Florida Survey.
