BAILEY. | Salt and Salt Brines. 13 
At Kanopolis, on the Union Pacific railroad, a salt mine has 
been in successful operation for more that ten years. At King- 
man there were two salt mines which did a thriving business 
for several years. 
Composition of Rock Salt. 
For purposes of analysis care was taken to get average sam- 
ples of the stock. The samples were thoroughly heated, to 
drive off.all moisture, before the analysis was made. In com- 
mercial salt there is often considerable moisture, as it is so 
readily absorbed from the air, and this moisture, of course, 
makes the salt by so much the less valuable. We should not 
expect to find so much moisture in coarsely ground rock salt as 
in evaporated or finely ground salts. The probable combina- 
tions of bases and acids are given. The Kingman salt has the 
following composition (analysis by E. H.S. Bailey and E. C. 
Case) :

Here the vein that is worked is more than eight feet thick. 
It will be understood that numerous other veins of excellent 
quality are pierced by the shaft before the depth noted above is 
reached. ‘These veins are separated from one another by soft 
shale or clay, and might many of them be worked to advantage.
