TIE CAVE MINI.
The Cave mine is situated twenty-five miles east
from Frisco and tho opposite sido Of tho Beaver
Wiley. through which tho main limo Of the Utah
Southern Railroad is to pass. It. Ia opened in tho
south end of The Mineral range of mountains which
Is there composed Of massive bods of limestone.

exist in this limestone, and which belong To series
Of ancient caverns that arc now for tho most part
filled with ore. The general character Of tho dcpos-
Its is similar to that of tho nines Of Eureka, Ne
