The most promising antimony deposits in British South Afrl appear to be those of tho Murchison Range,15 in northern TransVa The principal mine of the range is the United Jack'. In 1913--1 there was shipped from Transvaal 1,610 metric tons of concentra and crude antimony. In 1920 72 tons of regulus is reported toll been produced. Deposits occur also in the Steynsdorp distri in the Forbes Reef district, in Swaziland, and over a considerable'p tion of southern Rhodesia.18 " AUSTRALIA." The only important antimony-producing district in Australia is Costerfield. district of Victoria. The antimony concentrates aver1' about 48 per cent of antimony and also contain about 2J ounces' gold to the ton. The output in 1913-1919 was 16,406 long tons. The Hillgrovo district in Now South Wales was formerly a c6 siderable producer, the highest annual output being 2,450 tons of d in 1906: The antimony metal and ore produced in New South Wal 'in 1912-1919 amounted to 2,110 long tons. "" Imports of antimony ore into Great Britain from Australia in 10 amounted to 3,854 long tons, valued at $471,700. IJHall, A. L., Geplogy of the Murchison Range: South Africa Oool.

PRODUCTION BY STATES. In addition to the domestic lead ores smelted in this country, small quantities of domestic lead oro have been exported to smelters in Canada. In 1912 soft lead amounting to G3 tons was smelted from Wisconsin ores at Canadian smelters, and in 1913 soft lead amount-'' lngQ0. 7 t(in3 "V1*1 Wisconsin ores and desilverized lead amounting V? 98 tons from Idaho and Washington ores were smelted at Cana dian smelters. The desilverized lead smelted in Canada from Wash- ingtoL? re? am?unted 31 tons in 1914, to 137 tons in 1915, and1 to 2,001 tons in 191G. In 1917 silver-lead ores from Idaho and Montana smelted in Canada produced 4,570 tons of lead. Ores from Washington yielded 1,388 tons of lead at Canadian smelters in, 1918 and 3 tons in 1919, hut no lead ore from the United States was. treated in Canada in 1920.

LEAD FIGMENTS. Leaded zinc oxide, zinc-lead oxido, sublimed white lead, and sublimed blue, lead aro made directly from ore. Each of these pigments is discussed and the output given elsewhere in this volume m the chapter on lead and zinc pigments and salts.

The pigments manufactured from pig lead (whito load, red lead, orange mineral, and litharge) are also discussed and tho output given in the chapter on lead and zinc pigments. SECONDARY LEAD. Secondary lead is obtained mainly from shimmings, drosses, old metal, and alloys, such as babbitt, solder, and typo metal. The recovery of lead, by refining these materials constitutes an integral part of the lead industry. State. Alaska...................... Ariiona.................... Arkansas.................

In 1920, as in previous years, the Rush & Brown copper minq the largest copper producer in southeastern Alaska, Copper ' produced also at the Salt Chuck mine, better known for its prod' tion of palladium. Relatively little prospecting and no considers development work was done on the copper deposits of southeas Alaska. The three largo mines, the Bonanza, Jumbo, and.Mo Lode, were the only producing mines of the Chitina district in 19 and no considerable developments were made at other mines. So! alluvial copper was produced incidentally to gold-placer mining; the Nizina district. On Prince William Sound theBeatson mine tho only property operated systematically throughout the y The most notable advances were mado at tho Girdwood mine, wh systematic underground and surface work was continued duri much of tho year. Small developments wero continued atr' Schlosser and McIntosh mines through a part of tho year. / Tho above review shows that the Alaska copper-mining industr in a rather discouraging situation in spite of the relatively larger put of the metal in 1920. Except possibly in Prince William So' not much work was done during tho year in opening now ore bo The falling copper market ana certain local conditions havei couraged the launching of any new enterprises. Not only will, output of copper in 1921 bo far loss than that of 1920, but prob several years will pass before any new large copper-mining vent will bo under way. ' LEAD. The lead produced in Alaska in 1920 amounted to 875 tons, valu at $140,000, as compared with 087 tons, valued at $72,822, in 191, In 1920, as in other /ears, most of the output of lead was a by-prodd derived from tho gold ores of tho Juneau district. Tho increased 1920 over 1919 was derived largely from galena ore mined in/ Kantishna district. Tho recent development of rich silver-lead ores in tho Mayc trict3 of the Yukon Territory, about 100 miles east of Dawson, started a search for similar deposits on tho Alaska sido of the bo dary, not because of tho lead content of tho ore but because of/ rocent high price of silver. Galena ores are rather widely distribli in Alaska, but no largo deposits havo been found. Ihough so work was done on a number of Alaska galena deposits in 1920,1 ono mine, in tho Kantishna district, shippod any ore. * Cockfleld, W. E., The Mayo area, Yukon; Canada Geol.

COPPER. By H. A. C. Je n is o n .1 INTRODUCTION. The production of metallic copper from th consumption requires at^lcast three distinct smelting, and refining. Each of these operatio processes, of which tho preparation of the ore for the most varied and complicated. The Lake S ores are the only important American source the three operations are not necessary for the mercial copper. On account of these three ope to determine approximately the production of States by tho collection of mine statistics; refinery statistics. These three sets of statist exactly, but each set has a peculiar advantage, of all tlirco accurately determines the essential f industry for the year. The principal value of the mine statistics is most accurately the geographic distribution o are also the only source of accurate data on the tho copper and prccimis-motal contents of the o which the ore is concentrated before smelting. tity of ore shipped from the mines, but are le smel ter figures in that they represent the estimat content and not the actual recovery. The smelte fair accuracy the geographic distribution of the accurately the quantity of crude copper actual ores, including considerable copper from sulphu ceous ores that carry so little copper that the m it and frequently do not report it. The smel from the mine figures by the quantity of or materials in stock at tho beginning and at the e refinery statistics indicate the quantity of co for industrial consumption and the quantity recovered from coppor ore, but do not permit of p. roduction accordin_g to source,. even the seepp according to foreign and domestic sources B refinery figures differ from the smelter figures stocks of unrefined copper at the beginning and The principal cause of the differences in the f different sources is the time factor involved in of the production of refined copper, The interv ore is mined until the refined copper i's avai 1 The statistical tables la this report were prepared by Miss Helena M and exports were compiled from records of the Bureau of Foreign and Dom both of the United States Geological Survey, '
