Jn the coarse upper portion a great variety of minerals have been developed. Mr. Sickler enumerates the following: Quartz ordinary, milky, smoky, rose, and amethystine, also hyalite; orthoclase; albite; pyroxene; hornblende, green and black; spodumene colorless, strawyellow, lilac, and green; beryl colorless, green, yellow, and rose; garnet; epidote; tourmaline black and of many colors; micas lepidolite, muscovite, biotite, damourite, and cookeite; montmorillonite; amblygonite; triphylite; and among the metallic oxides, hematite; sulphides, pyrite and molybdenite; bismuth, native and the oxide; also apatite, siderite, and columbite.
On the Hiriart Mountain there seem to be numerous dikes instead of one or two great ones, as on the other two ridges. Many outcrops and openings show lepidolite. and several show kunzite at various points on the ends and on both sides of the ridge. Eleven claims are located and more or less developed. These are the following:
San Pedro claim, north end; by Bernardo Hiriart and Pedro Teiletch; lepidolite and gem spodumene.
Sempe claim, crest and west slope; by the same; lepidolite. bend, and colored tourmaline.
Anita claim, west side; Hiriart and his jiartner; lepidolite.
Catarina claim, south side; Hiriart and M. M. Sickler; lepidolite, amblygonite, and gem spodumene at two openings.
El Molino claim, south side; F. M. and M. M. Sickler; gem tourmalines.
Center Drive claim, south side; by the same; beryl and gem tourmaline.
White Queen claim, south side; F. M. Sickler; lepidolite, beryl, and spodumene. This is the mine where the first kunzite crystals that reached the writer were found in 1902, as above mentioned.
Hiriart claim, south and east side; M. M. and F. M. Sickler; lepidolite and gem tourmalines.
Vanderberg claim, south slope; M. M. Sickler; lepidolite, beryl, gem tourmaline, and gem spodumene.
Nay lor claim, east slope; F. M. and M. M. Sickler; lepidolite and gem spodumene.
In addition to these the Sicklers, father and son, own the Fargo claim, on the west slope, which is promising, but hardly developed. They have recently reported the finding of a very fine, deep-colored crystal of kunzite, almost flawless, measuring 12.5 by S by 3 centimeters, at one of their newer claims on this mountain, 20 feet in the ledge and 16 feet from the surface.
Two separate accounts have appeared as to the composition of kunzite spodumene, which are in the main closely accordant. One of
