8vo. Report to the Secretary of War, Feb., 1879; ea by 
order of Constant e Pagosa Springs are situated in the valley 
of the San Juan river, southern Colorado, on the road from Tierra 
the depth not determined. An apparent ebullition goes on con- 
stantly, but it is gaseous and not due to boiling, the waters rising 
charged with hydrogen sulphide and carbon dioxide. The tem- 
perature of this spring was found to be 141° F., that of the river 
being 40° F., and the highest er te ag being 49° (Decem- 
ber); the temperature at the exits into the river—the outflow is 
subterranean—was 127° F. The waters pe besides the gases, 
chiefly calcium carbonate and sodium sulphate, with smaller quan- 
tities of sodium chloride, sodium, magnesium and lithium earbon- 
ates, and otal sulphat e. The deposition of solid matter goes 
on quite rapidly, stalactites and stalagmites, consisting chiefly of 
calcium carbonate and sodium me ee formed within the 
pools.
