others contain silica, organic matter, etc., and are said to possess 
medicinal properties. 
Many of these springs are of a temperature higher than that of 
the surface of the earth where they make their appearance. At 
Carlsbad and Aix-la-Chapelle the temperature varies from 160° 
to 190° F. Such hot springs generally occur in the vicinity of 
volcanoes and are represented by the hot springs of New Zealand. 
In New Zealand some of these springs are situated at 1,200 feet 
above the sea, some being cold, others warm, and the rest hot, 
having a temperature of 117° F. In the North Island, the springs 
flow through probable natural artesians, coming up to the surface 
from a depth of some 3000 feet. The waters obtained from a bore 
at Youngarina and Native Dog (N.S. Wales) had a temperature 
of 82° and 92° F., while water taken from an artesian bore at 
depths of 1,175 feet and 450 feet at Bourke (N.S. Wales) gave a 
temperature of 102° F. 
There is a large field open for the examination of our mineral 
waters, a number of which if thoroughly tested would no doubt 
be found to possess medicinal properties, and hence be of value. 
The districts might be made health resorts or sanatoriums, where 
visitors could stay and enjoy all the advantages of a club-house, 
and the benefit derived from the waters of the spring. 
‘In Queensland Mr. H. Faash has leased the Innot Hot Springs. 
from the Government, and constructed baths and a two storied 
house for the convenience of patients. The water when taken is 
stated to have an aperient action, but patients undergoing treat- 
ment combine bathing with the drinking of the waters, two or 
three baths of a duration of twenty or thirty minutes being taken 
daily. These springs have already gained a considerable reputa- 
tion for their curative virtues in chronic rheumatism, gout, liver, 
and kidney diseases.” —(Mineral Springs of Australia, by Ludwig 
Bruck.)
