SIX months or tnlS year as compared with the first half of 1915, but it has been largely in the direction of the reopening of old properties that have been idle. several of them for many years. according to the United States Geological Survey. Reports from the United States mint at San Francisco, and local smelters and refiners show that they are in receipt $366,OO0 less, California gold, and 22 900 ounces more silver, in the first five months of 1916, than in the corresponding period of 1915.
 Aside from the gold, silver, copper and lead mining industries of the state, there has been thus far in 1916 a heavy demand for such mineral sub stances as chromes, tungsten, magne- site, manganese, antimony and others. great many mines of this character have been opened and are shipping For the first time in history many of these mines are shipping crude ore to the eastern seaboard by rail the high prices permitting this.
 There has been no noticeable in crease thus far this year in the num- Der of productive gold mines in the state. During the first half of 1916 there has been greater gold mining ac- tiVity in the mother lode counties than has been the case for many years. These five counties produced 61 per cent of the annual output of sliceous ores. The older mines all are reported doing we'll
 1 Deep mining outside of the mother lode section of the state also is unus- ually active In the Grass Valley dis trict, Nevada County, both the North | Star and Empire mines, the leading producers, are finding high grade ore in the depth. In the Providence, of the Champion group. Nevada City, a strike of high grade ore, carrying tel luride, has been made In this sec tion a number of small and idle mines are coming into possession of the larg CT companies in order to improve their positions in the district
 In the southern counties of the state notably in the desert regions of Inyo San Bernardino, and Riverside coun- ties, there is a distinct revival of min ing activity, largely brought abou through the adoption of auto trucks fol delivery of ore to the railway stations for shipment to reduction works.
 The gold dredging industry of thu state continues in a flourishing condi tion The dredges produce S5 pc cent of the placer gold in CaIifornia and 3S per cent of the total gold yield The larger companies have been add ing new machines to their equipment . and these are invariably of great ca pacity several costing half a millio dollars each it is said. The neN dredge of the Natomas Company in tn Folsom district designed to restor ground to it's natural condition afte dredging, permitting it's use for agri culture, has demonstrated it's efficiea cy, according to reports.
 Extensive areas of placer groun near Bedding have been bonded an are being prospected for dredging More than 1,500 acres of dredgin ground along the Trinity River. fror Lewiston to Poker Bar, have been ac quired by capitalists, and one dredg is to be in operation this summer; tw more probably next year. Dredge ma chinery from Ohio, for the dredg near Carrville, amounting to 2,000 ton is being hauled from the railroad Q Redding 62 miles into the mountain 300 mules being used for the haulin work. The largest dredge in tn world according to reports. has bee completed and set to work on the Yu ba river. near Hammonton.
 Hydraulic mining has not been yer active outside of Trinity and Siskiyo counties but some new mines hay been started in Central California. merger of hydraulic mining interest is. reported being made in the stat Creek district, Sierra County and ex tensive work is said to be contem plated, under supervision of the Cali fornia Debris Commission A mammot restraining dam is to be put acros Stat Creek, which will permit, whe completed, hydraulic operations a Scales, Port Wine, Whiskey Digging. Gibsonville. La Porte, and Other fam ous old camps, that have been lon idle.
 A revival of drift mining in the stat along the Magalia ridge in Butte coun ty has brought about numerou changes, it is reported, and the reopen ing of many old properties. The ol South Fork property, on Oregon Creel Sierra County, is now continuing tn 6900 feet bedrock tunnel to try t reach the channel in the extension ( the famous old Bald Mountains drii mine s Copper mining in the state has bee very active in 1916. owing, it is sait to the high price of the metal. Tn lrager companies are said to have in creased miners wages in the form ( a bonus while electrolytic copper sell at 20 cents a pound or more. Ne copper properties have been opened Trinity, Siskiyou, Plumas, Madeira an other northern counties as well as several of the southern counties of tf state.
 The Eagle Copper Company, Plumas, is using the Notation proces to concentrate it's ore before beir shipped to Nevada smelters.
