 smelted from arsenical and antimo-
 nial ores. This lead is de-silverized
 with great ease, an advantage, not
 only of economical importance as
 respects ease of working and product of silver, but as giving a lead almost
 free of silver and therefore much better adapted to the manufacture of white lead, and much more valuable | for that purpose than if it contained
 any silver. The presence of an ounce
 of silver in a ton of lead affects the corrosion of the lead in no slight
 degree. Lead which corrodes easily
 and completely is the best for mak- l ing white lead. Lead holding silver
 does not corrode so sapidly and com pletely as pure lead. and white lead containing silver darkens on exposure to sunlight. The Castle Dome galenite is remarkably free from arsenic and antimony. At a depth of 600 feet water is found and the galenite is oxidized with the formation of beauti- full crystallizations of carbonates of lead and of wulfenite and of vana- dinite.
 Silver district is another lead bear ing region adjoining Castle Dome on the north. It has larger veins and the ores are richer in silver but have not the regularity of occurrence and distribution of galena character izing the veins of Castle Dome. At the time of the first locations on the veins nodular masses of galenite weighing many pounds could be picked up on the croppings of the Silver Glance claim. having in the course of ages been weathered out from the gangue. Some of the veins are remarkable for the gangue or veinstone of heavy y-spar, the sulphate of barytes-barite
 The Mowry mine in Santa Cruz county. about twenty miles south of Patagonia, has long been noted as a producer of lead ore. partly galena and partly carbonate of lead. a mix ture favorable to smelting, which was availed of in the early sixties, and before, by the erection of simple adobe furnaces. This is one of the historic mines of Arizona, brought into prominence largely by Sylvester Mowry. the first delegate of the ter ritory to congress, and often styled the inventor of Arizona"
 The Hardschell and Flux mine, also in Santa Cruz county, has been a large producer of low grade lead ore suitable for fluxing other ores. It is largely a carbonate resulting from the oxidation of galena, but carries about 10 ounces of silver to the ton and 10 per cent lead in the large way
 The Worlds Fair mine yields a considerable quantity of galenite in association with blende and high grade ores of silver, and native sil- yer.
 Very fair crystals of galenite are found in the ore of the Silver Belt claim. Big Bug. Yavapai county. and in the Kasser claim near Globe, where, as in many other localities, 1t is closely associated with wulfen- ite, the molybdate of lead indicative of the presence of mo1ybcenum in the galena.
 Hands mines in the Chiricahua mountains, Cochise county. produce not only galena in quantity. but lead carbonate also.
 The old Yuma mine. twenty miles northwest of Tucson, has been a large producer of lead ore.
 Cerro Colorado and the Liberty mines have also been large producers.
 San Xavier mines, Sierritas, south of Tucson, with sphaterite.
 Jack Rabbit mine, ten miles east of Vekol.
 At Mineral Hill, Pinal county, in the Alice vein.
 At the Great American mine, Swishelm mountains.
 At the southern end of the Hua- chuca mountains. not far from the boundary line, it oc- CUTS with zinc blende in limestone.
 At Greaterville. in veins near An At the Salero in the Flu reka, Thunderer and Mabel claims, in a gangue of manganese spar.
 The Vekol mines. Pima county, l have yielded large masses of lead ore in combination or mixture with | high grade silver ore. Spescimen l masses in the museum at the uni have yielded by assay as high as 400 ounces of silver to the | ton. There is much oxide of lead | and carbonate in the ores. Galena | has also been mined in quantity from | the Liberty mine southwest of Tue | son.
 In the olive district the Paymaster | and other mines have been large pro- | ducers. Galena mixed with blende | is abundant at the San Xavier mine. |
 Galena is large masses has been | extracted wrom the Manila mine at | the northern end of the Huachuca | It occurs also in dis | seminated grains in a quartz of | gangue at the croppings.
 In Cataract Canyon, a tributary of | the Colorado, part way down the Grand Canyon.
 In the Mineral Creek country north of Troy and Kelvin.
 In the Aztec, Tyndall and Salero | Santa Cruz county, there | are many localities of massive lead | ore, notably at the Trenton.
 In quartz with wulfenite, 2h miles northwest of the Desert gold mine.
 It is reported from the Arizona in the north end of the Aztec district, in association with copper ore, about nine ounces in silve and a trace of gold. Similar ore is found on the Leek- Mcdonald property.
 Montana mine, Orc Blanco district, Santa Cruz county, with sphalerite.
 At Mark Lulley's mine. the Wan lering Jew" in the Santa Ritas,
