The Bryan daily eagle. (Bryan, Tex.) 1895-1898, 1897-01-06


eral region OF Texas. This area was
10 named by the Texas Geological Sur
vey in their several annual reports. II
embraces the western half Of Burnet,
all Of Llano. and q part Of Mason. Gill
lospio. San Saba. Blanco and Kimblo
counties.
Prof Cummins said:
"lhere Is a greater variety Of min
erals In that area than In any other Of
the same size In tho world. Most Of them
are yet undeveloped. and Il Il still a
question whether many Of them are In
paying quantities. Prospecting has
been going on In that region after
fashion since tho days when the Mex
leans first settled the al jacent territory.
and many arc the traditions about val
liable mines having once been In sue
ccssful operation In that territory.
Every once In a while some old shaft or
furnance Is found that starts anew the
search for these lost mines. Some PEG.
pie still beliove tho old Bowie mine will
yet b. discovered. Notwithstanding the
numerous failures that have been made
In searching for H.
Gold has been found IN small guam
titles inssversl places In this region.
and the manner Of It's occurrence has
led TO the belief that Il would BE- found
ultimately 10 paying quantities. and a
great deal oiprcspeciing has been done
IN attempting 10 discover deposits that
would pay. but hitherto these Efforts
have been uayailing. More recently
some prospecting has been done In
Blanco county that bids very fair az
present 10 devo.ol some COOL paying
mines. Cold can be WASHED olt OF tho
