654 MINERAL RESOURCES, TJ13—PART 11.
Another
small cabochon gem 2.0 by 0.9 centimeters shows a perfect grove of
small bushy trees with brown foliage and black trunks. Tin lower part
of agate contains a peculiar yellowish stain.
A
beautiful pendant, 3.7 centimeters long, 1.5 centimeters wide*l the
lower end and tapering to 3 millimeters at the top, shows a den-drite-like pine tree in fine translucent gray agate.
A
number of gems contain one or more d^idrites resembling many varieties
of moss, ferns, or seaweeds with delicate spreading branches. Among
them is a thin, round cabochon stone 2.3 centimeters I diameter, which
shows three branching ferns or seaweeds with extremely delicate
structure. In other stones various objects, such as the "Mexican eagle"
with spread wings, the Austrian om battleship with fighting top, etc., are readily recognized.
Among the cut stones loaned by Mr. Hanson, of Billings, are » showing beautiful dendrites resembling trees, patches of moss, a ferns,
and a few with good landscapes. Mr. Hanson's collection of rough and
cut agates was prepared with a view to showing the mode of occurrence
of the moss agate and the method of elaboration. 4
OREGON.
Mr.
Don Maguire, of Ogden, Utah, reports the occurrence of fine
brown-stained moss agate on McAllisters Butte, near Ochoco River, in
Crook County, Oreg.
WASHINGTON.
Specimens
of rough and cut lavender-blue chalcedon}- were receive! from Mr. A. L.
Delkm, of Seattle, Wash. The rough agate was gatiaH from the sage-brush
country around Ellenburg and is reported to be rare. The material is
very similar in appearance to that from Myrick's prospect in
California, described above. Mr. Delkin reports a good sale for the cut
gems.
AMETHYST.
MAINE.
Of
the several localities where amethyst has been found in Maine one was
examined in June, 1913. This is on Deer Hill in the town of Stow, If
miles N". 30° E.of North Chatham, N. II. Deer Hill was also visited by
E. S. Bastin 1 in 1906, but more prospects hare beei
opened since that time. The deposit is on the land of Chester Eastman
in the ridge extending south from Deer Hill. One of the new prospects
is 20 feet long and 8 feet deep, and other similar pits have been
opened within a distance of 150 feet northeast along the «fl side of
the ridge. The old work consisted of numeious small J in the gravelly
soil of the ridge for a distance of about 100 yaiqj northeast of the later work.
The
country rock is chiefly granite gneiss, but pegmatite covers-much of
the ridge at the amethyst locality and is the rock opened by the
prospects. A large ledge of quartz is inclosed in the pegmatite having
a strike of N. 40° E. and a dip of 35° SE. Geode-like pockets of quartz
crystals were opened in the later work along the contact of
' Geology of the pegmatites and associated rocks of Maine: U, S. Geol. Survey Hull. 445, p. 102,19U.
