*The figures of the Director of the Mint for the production of silver in the Uni- 
ted States for 1892 have been discredited, and consequently are not reproduced 
here. +The statistics of gold and silver production in 1893 was collected for this 
work, but we are indebted to the Director of the Mint for the approximate distri- 
bution by States, etc.

“The output from California was somewhat less than in 1893, but that 
from Utah increased slightly, and a very considerable increase came from 
the Texas deposits, though the Kentucky production was somewhat less. 
The asphaltic rock from Texas has increased in quantity, and has also a 
much higher average value than that of previous years.”
