I SliItOlt, uiSttlSt- 1hCoC SAyo tals were identified by Pirsson and Penfield of Yale university as re- sembling the stout hexagonal prisms of the original locality at Moresnet.
 WoLFRAMITE. Tungstate of iron; approximate competition. Tunsstic acid 75.0. fer rous iron 25.0.
 A part of the iron oxide may be replaced by manganous oxide. If there is more manganous oxide than | ferrous oxide the species is known as "hubnerite," the tungstate of manga nese.
 The color of wolframite is darker and blacker than the brown of hub | nerite.
 It occurs with the Gigas deposits of hubnerite, and sparingly with those of the dragons. Also in a quartz vein on the southeast side of San Cayetano mountain, about seven miles north of Nogales.

Cochise county. in granite.
 In the Aquarius range of mountains. Mohave county. wolfram occurs in promising quantity. Shipments have been made to eastern works.
 WULFENITE. MoIybdate of lead; molybdenum trioxide 39.3, lead oxide GOT.
 A common associate of the oxidiZed lead ores of Arizona often confounded. in name at least, with the species of wolframite with which 1t has no af- filicticn. Its close association with galenite at so many different locali- ties leads to the belief that molybde- mum occurs in the form of sulphide in the galenite, either enfolded in the crystalline or cleavage planes, or in such close combination as not to be recognizable except by the products of oxidation with the formation of the highly -colored molyboate of lead.
 In this form 1t occurs at Castle Dome in beautifully honey-yellow crystals at the water level in the Railroad claim implanted on white crystals and crystalline aggregates of Cerussite. the carbonate of lead.
 Some of the finest specimens yet obtained of wulfenite were taken from the Mammoth mine in Silver district in tabular crystals over an inch in width and deep, rich red color Another mine in the same district, the Hamburg. has yielded crystals remarkable for their dark color and octahedral habit, sprinkled upon slabs of black limestone.
 The old Yuma mine near Tucson has yielded some tabular red crystals of large size and good color. closely associated with vanadinite.
 The Mammoth gold mine at Shultz. Pinal county. has yielded probably the finest crystallized groups of this min eral and in a massive form in the greatest profusion, for though great care was taken to separate the masses of galenite and of wulfenite from the auriferous quartz before crushing and milling, 1t appeared in quantity in the tailings, which afterward became an available source of the mineral. Two or three car loads were washed out of these tailings by sluicing.
 Found also near Schneider's mine. Dripping Springs range.
 ZINC.
 For ores of zinc, see Blende. cala mine and Smithsonite.
 ZlNkENITE.
 Sulphide of lead and antimony.
 Sulphur 22.3, antimony AIS. lead 35.s. From near Prescott, Yavapai county.
 Arizona is fortunate in the posses sion of building stones and other ma terials of construction in great va riety and wide distribution. There are granltes of various grades and tints of color. porphyries, andesites stones. Limestones abound suitable for burning for lime or for buildings.

At Oracle a coarse grained, gray granite weathers out into large boul- ders of disintegration. Near Phoenix very fine granite 1 rock of a dark-grey color is specially 1 suitable for monumental work.
