	PRODUCTION. The total value of the gold and silver output of Idaho in 1904 was §6,099,369, an increase of $786,460 over that of the preceding year. The total gold mined in Idaho during the year 1904, according to reports returned by producers, was 82,739 fine ounces, valued at $1,710,365. The gold yield for 1903 was 65,850 fine ounces, valued at $1,361,119, an increase for 1904 of 16,889 ounces in quantity and of $349,246 in value as compared with 1903. In 1904 Idaho produced 7,666,382 fine ounces of silver of commercial value, at 57.25 cents per ounce, of $4,389,004, an increase of 267,412 fine ounces and of $437,214, partly due to the increase in price. The following table shows the gold and silver product of Idaho compared with 1903: Production of gold and silver in Idaho, 1903-1904, by mines.



	The gold and silver returns from deep mines show that 1,668,327 tons of ore were crushed, which 3'ielded in 1904 the sum of $5,602,003. The deep mines yielded in 1903 the sum of $4,930,854, so that the figures of 1904 show that they increased their yield $671,149. From the placer or surface mines the quantity of material washed was not reported. The value of the yield of gold in 1904 amounted to the sum of $493,002, an increase over'the yield in 1903 of $114,183. Thus it is shown that both deep and placer mines are increasing their product. In the report of precious metals production for 1903, the Survey did not take into account the entire output of Snake River placers. Snake River winds its way through and on the border of twelve counties. These are Fremont, Bingham, Bannock, Oneida, Blaine, Cassia, Lincoln,
