Silver and Gold . — * * * * ‘‘That there are such valuable deposits in 
the State, however, there can he nO' do'uht, and analyses of gold and silver 
ores found in iTexas of even great value have been made in the laboratory 
of the University. !So far as my experience goes, the ores of bo'th gold 
and silver lare much more valuable in the western and northwestern por- 
tions of the State than in the central. Of many ores examined from Llano 
and the adjacent counties none of great value were found, although some 
were fair low grade ores. * * * in some of the streams of Llano 
county it is poissible to pan out gold in even paying quantities, and it is 
to be hoped that the time is not far distant when competent geologists will 
be able to locate the source of ithis metal in that portion of the State. 
“Oine of the most rematrkable deposits of gold ever found is near Austin. 
It is remarkable from the fact that the gold is found in a ki,nd of rock 
which has hitherto been supposed to be free from gold. iThe metal seems 
to be very unequally distributed through ordinary limestone, and does not 
occur in any well defined veins at all. This will probably prevent its 
succesisful working, for while one ton of the rock might yield $50 of gold, 
still the next ten tons would be likely to yield not a cent. 
“From the extreme northwestern part of the IState some very fine indi- 
cations of gold have been found. A small nugget about as large as a 
pigeon’s egg has been received at the laboratory. It is said to have been 
found in Oldham county. 
“A few examples of the ores assayed for gold and silver are given: 
“Silver ore from Northwest Texas showed 150 oz. of silver to the ton of 
2000 lbs. 
“Gold ore found in limestone contained: (Silver, 6 oz. to the ton of 
2000 lbs.; gold, $17 to the ton of 2000 lbs. 
“argentiferous galena. 
No. 1 contained 15 oz. silver to the ton of 2000 lbs. 
No. 2 contained 20 oz. silver to the ton of 2000 lbs. 
No. 3 contained 120 oz. silver to the ton of 2000 lbs. 
No. 4 contained 10 oz. silver to the ton of 2000 lbs. 
No. 5 contained 23 oz. silver to the ton of 2000 lbs. 
“One of the richest silver ores it has ever been my lot to assay was found 
in this ^State, and it contained, according to the analysis, over 5000 oz. of 
silver to ithe ton. 
“Iron Ores^ * * * 
“The following partial analyses of iron ores from different parts of the 
estate will give some idea of their value:
