AMONG THE
ROCK HUnTERS
Despite hot weather and earthquakes. Imperial
Valley Gem and Mineral society voted
to continue its semi-monthly meetings during
the summer. Many members are exhibiting exceptionally
beautiful geodes and "thunder
eggs," obtained on recent field trips.

Dale Lambert, secretary of Columbian Geological
society, of Spokane, Washington, reports
an overnight field trip to Vantage Ferry,
May 18 and 19. Members of the Spokane society
camped Saturday night at the east end of
Vantage ferry bridge, where they were joined
next morning by representatives of Seattle
Gem club. The group then traveled about 10
miles south and east to the Saddle mountains.
Many excellent specimens of petrified wood
were obtained and also some Indian arrowheads
and artifacts. The Spokane group was
under the leadership of Mrs. Bruce Neal; C.
E. and Mrs. McDonald directed the Seattle
contingent.
Los Angeles Mineralogical society heard an
interesting report on the Almandite garnet
deposit on the Tejon ranch, where the garnets
occur in diorite. Methods of identifying minerals
were demonstrated. Field identification
may be made by color, luster, streak, hardness,
etc. For further identification the blowpipe,
polariscope, microscope, chemical analysis or
tests for specific gravity may be employed. On
the field trip to Shadow mountain tungsten
mine in the Mojave desert, fluorescent lamps
were used to locate the mineral.
Kern County Mineral society reports an instructive
talk by Jess Stockton of Kern county
union high school on the history and development
of tungsten mining in Kern county.
The society is considering incorporation.
Washington State chamber of mines has
purchased, through cooperation of one of its
members, Jim Arnaud, a trailer which is available
for use by members. It has a patent hitch
that allows it to be attached directly to the
bumper of any car, and is designed for loads
up to half a ton.
Washington State has a new shallow water
gold dredge which will work the gravels of
the Lower Swauk, from the vicinity of the old
Ellensburg-Blewett highway corner up to the
tailings of former dredging operations in the
Swauk. Dredging will be facilitated by dragline
and bulldozer equipment.
Ferry mine on Redtop mountain, northern
Stevens county, Washington, announces the
strike of five feet of solid Galena. The oreruns
between $60 and $100 a ton.
Washington state chamber of mines has received
so many interesting and beautiful mineral
specimens that the collection has outgrown
the cabinet space, and additional showcases
are needed.
Joseph D'Agostino, secretary of the Plainfield,
New Jersey society, states that the name
Calamine -- H2Zn2Si O5 (English) is no
longer used, and that the correct term is
Memimorphite.
Boston Mineral club has elected the following
officers: Dr. Cornelius S. Hurlbut, president;
Henry G. Savage, vice president; Dr.
John W. Estabrooks, treasurer; Mrs. Grace
G. Dearborn, secretary. The Boston club draws
its membership from about 50 outlying towns
as well as from Boston. The April speaker
was Roscoe J. Whitney, who selected the
topic "Where Mineral Collecting Has Taken
Me."
