it has declined to $6,000,000
at the present time. The total product of silver in Nevada has amounted
to $340,000,000. The largest nugget of silver yet obtained was dug up in
Arizona, and weighed 43,200 ounces, valued at the same number of
dollars. The highest silver deposit in the world is on King Solomon's
mountain, in Colorado, fourteen thousand feet above the Pacific Ocean.
The annual product of the silver mines of North America is estimated to
be $76,480,000. Their total product has amounted to $4,783,000,000, more
than one-third of the entire product of the world from the earliest
times to the present day. The annual product of the silver mines of
America at the present time is estimated to be $98,480,000, and their
total product has amounted to $7,170,000,000, more than three-fifths of
the entire product of the world, from the earliest times to the present
day. The export of silver from the United States, since 1848, has
amounted to $413,292,757. The annual product of the mines of Europe at
the present time is estimated to be $15,000,000; and their total product
has amounted to $2,600,000,000. The annual product of the silver mines
of Asia (including Australia, New Zealand, and Oceanica), at the present
time is estimated to be $480,000; and their total product has amounted
to $1,685,000,000. India has often been represented as destitute of
silver, but we have statements from Sir Roderic Murchison that the Kulu
valley is so rich in silver ore that it could yield a large product for
future ages. The silver country of Vasours comprises the mountainous
regions between the Beas, Sainji and Parbutti rivers. The mines, though
previously worked, are now almost forgotten. The same is the case with
the Manikarn mines, hitherto known to be incalculably rich. The annual
product of the silver mines of Africa is estimated at the present time
to be $40,000; and their total product to the present time has amounted
to $389,000,000.

Silver, to the amount of $2,913,000,000, is estimated to have been
obtained from the mines of the earth from the earliest times to the
commencement of the Christian Era; from the date of the latter event
to the discovery of America $521,000,000 were obtained; thence to the
close of 1847, an addition of $6,025,000,000 was made; thence to the
close of 1884, there was added $2,344,000,000; making a grand total of
$11,803,000,000. The average loss by abrasion of coin is estimated by
Professor Bowen at one
