Close Estimate on Quicksilver

Close Estimate on Quicksilver
 The final figures for the production
 of quicksilver in the United States in l 1914. received by H. D. McCaskey, | of the United States Geological Sur vey, are only one-tenth of 1 per cent l less than the figures given to the pub lie in the preliminary estimate of Jan
 uary l. 1914. The preliminary figures given were 16,56S flasks of 75 pounds | each, having a totaLvalue of s811,832 | The final figures 16.54S flasks, val ued at $811,6SO, showing a decreased l output of 3,665 flasks compared with 1 the production of 1913. This decrea SC l was entirely due to a much smaller yield from California. The production | from California, which amounted to 15- | 591 flasks, valued at $627,2 in 1913 | was only 11,o03 flasks, valued at s554 | 414 in 1914. The production of Nevada l increased from 1.645 flasks, valued at l s66.17S. in 1913. to 2.0S9 flasks valued l at S102, ,465, in 1914. The combined out put of Arizona and Texas increased 1 from 2,977 flasks, valued at S119,765, in 1913. to 3,156 flasks, valued at $154,S01
 in 1914.
 1 The average San Francisco price 1 from January to July ranged from s39.25 to s3750 a flask. During the l last five months of 1914 the price fluc- 1 tuated greatly and sales were reported exceeding s100 a flask. The average San Francisco price for 1914 was
 $49.O5. against s40.23 in 1913 and s42.05 in 1912.
 None of the mines in Oregon, Utah, or Washington reported any produc- tion ir 1914, and the output was de- rived from 20 properties in California. : in Nevada, and in Arizona and Texas.
 The total quantity of ore and furnace material treated in 1914 was 122,9SS short tons, and the average recovery was 101 pounds of metal per ton. against an average recovery of III pounds per ton from 136.27S tons in 1913. Only 5.525 tons of ore was treat ed in retorts, which yielded 917 flasks of quicksilver. and the remainder of the ore. or 117,473 tons, was treated by furnices.
 The present high prices have stimu- lated the search for new ore bodies and also the active operation of the old pro- perties. but the present outlook does not indicate any largely increased do- mestic production.
 Quicksilver is used mainly in the manufacture of fulminite for explosive 1 caps. drugs, electric appliances and scientific apparatus. and to a dimin- l ishing degree in the recovery of gold | and silver. It is the increased demand | for explosives and the domestic short ! age of supplies that have so greatly | advanced the price of the metal. The l quantity of quicksilver used in the ' United States in recovering precious | metals has shown 8 steady decline in | recent years. It is estimated that the . quantity so used has decreased from | 1.290 flasks in 1911 to 1,150 flasks in i 1913. This was less than per cent of | the domestic quicksilver output and of { this more than 50 per cent of the quan- tity so used in 1913 was by California mills
 Production of Silica (Quartz) in 1914
 The quantity of quartz or other materials marketed in 1914 for the manufacture of pottery, paints, wood filters, poll hers.- abra- sives and other articles, was 1S1. .731 short tons, valued at S612.S29, as re- | ported by F.
